There are places in Ireland where history does not feel distant. It rises from the landscape, stands among the trees, follows the course of a river and watches over the fields from the top of a hill. Sometimes it appears as a magnificent fortress; sometimes as little more than a weathered tower or a few stones hidden beneath the ivy. Yet every ruin has a story, and every story is part of the extraordinary tapestry of Ireland.
Across the island, castles, tower houses, monasteries, fortified homes and ancient strongholds have survived centuries of change. Some were built to defend a territory, others to proclaim the power and wealth of their owners. Many witnessed battles, sieges, political upheavals and rebellion; others simply endured the quieter passage of generations. Today, their walls may be broken and their roofs long gone, but the places themselves still have an extraordinary ability to make us wonder who stood there before us, what they saw, and what happened behind those ancient stones.
Our own journey began almost by accident. A few years ago, on a warm summer day, we came across the ruins of Carrigogunnell Castle, near Clarina in County Limerick. We knew very little about it when we arrived. We certainly did not expect that a ruined medieval castle, standing quietly above the Shannon valley, would become the starting point of something that would accompany us for years.
But there was something about Carrigogunnell that stayed with us. Its isolated position, its dramatic silhouette and the landscape stretching out beneath its walls made it impossible simply to visit and leave. We wanted to know its history. Then we wanted to see another castle. And then another one.
That curiosity gradually became Castles of Éireann.
What began with a single ruin turned into a journey across Ireland in search of forgotten places, remarkable landscapes and the stories hidden within them. Some destinations are famous and carefully preserved; others are little-known ruins that can easily be missed unless you know where to look. We have found ourselves walking through forests, crossing fields, climbing ancient walls and, occasionally, retreating rather quickly when an enthusiastic Irish dog decided that we had wandered somewhere we were not supposed to be!
Along the way, we discovered that the fascination of these places lies not only in their architecture. It is also in their setting. A castle can tell you something about the people who built it, but the landscape around it often tells you why it was built there in the first place. A river, a mountain pass, a harbour, a fertile valley or a distant view of another stronghold can suddenly make an old ruin come alive.
This website is our attempt to share that sense of discovery.
We are not simply collecting pictures of beautiful ruins. We want to understand the places we visit and to bring together their history, architecture, legends and surroundings in a way that makes you want to discover them for yourself. Some stories are well documented; others have been shaped by centuries of tradition and local memory. Wherever possible, we try to distinguish between what we know, what we can reasonably reconstruct and what belongs to the fascinating world of legend.
So take your time. Explore the map, choose a castle at random, follow a road into the countryside or search for a place you have never heard of before. You may find a great medieval fortress, a forgotten tower house or nothing more than a fragment of a wall covered in ivy. Whatever you find, remember that the most unassuming ruins can sometimes have the most remarkable stories.
Ireland has been changing for centuries. Its castles have changed with it. Some have survived almost intact, some have become magnificent houses, and some have surrendered themselves to the landscape. But they remain witnesses to the people and events that shaped this island.
We invite you to follow their stories, discover the places where they still stand and, perhaps, find a few that you will want to visit yourself.

Symbols
A
AOS SÍ: The supernatural people of Irish tradition, often associated with ancient mounds, fairy forts and places believed to connect the human world with the Otherworld. They are not simply tiny, winged fairies, but powerful beings who were traditionally treated with respect and caution.
B
BANSHEE (BEAN SÍ): A female supernatural figure whose mournful cry traditionally foretells a death in certain Irish families. Accounts vary between regions and stories, with the banshee sometimes heard lamenting and sometimes seen at a distance. She is associated with death and forewarning rather than simply being an evil spirit.
BEALTAINE: A traditional seasonal festival marking the beginning of summer, celebrated around 1 May. Historical and folkloric accounts associate it with fire customs, protection for livestock and the transition into the warmer part of the year. Its practices varied across Ireland and over time.
BOOK OF KELLS: An elaborately decorated medieval Gospel manuscript, famous for its intricate lettering, animal motifs and interlaced ornament. Usually dated to around the late eighth or early ninth century, it is a masterpiece of Insular art. Its precise place of production remains debated.
BODHRÁN: A traditional Irish frame drum played with a small wooden beater. The musician can alter its tone and rhythm by controlling the inside of the drum skin. Today, the bodhrán is widely associated with traditional Irish music sessions and performances.
BRAT BRÍDE (ST BRIGID'S MANTLE): In Irish folk tradition, a piece of cloth or ribbon could be left outdoors on the eve of St Brigid's Day to receive the saint's blessing. It was then kept for protection or used in healing customs. The practice illustrates the connection between religious devotion and seasonal folklore.
BRIGID, THE GODDESS: A figure in Irish mythology associated in later sources with poetry, healing, smithcraft and creative power. She must be distinguished from St Brigid of Kildare, the Christian saint celebrated on 1 February. The relationship between the goddess, the saint and earlier traditions is complex.
BRIGID'S CROSS (CROS BHRÍDE): Traditionally woven from rushes or straw around St Brigid's feast day on 1 February, these crosses are displayed in Irish homes and farm buildings. They are associated with blessings and protection for households, animals and land. Several regional designs exist.
C
CELTIC CROSS: A cross featuring a ring around the intersection of its arms, commonly associated with Ireland's Christian heritage. It appears on monuments, gravestones and jewellery. Although often linked with ancient Celtic spirituality, its familiar forms belong chiefly to Christian artistic and memorial traditions.
CELTIC KNOTWORK: A family of decorative patterns formed by interlacing lines and loops. Common in medieval Irish manuscripts, metalwork and stone carving, knotwork is now widely associated with Celtic artistic heritage. Modern interpretations often connect it with eternity or interconnectedness, although individual designs do not necessarily have one fixed ancient meaning.
CÉILÍ: A social gathering centred on Irish music and dancing. Céilí dances are often performed by groups or couples following set figures, accompanied by traditional musicians. Modern céilithe continue to bring communities together and help pass Irish dance and music between generations.
CHANGELING: A figure in Irish and wider European folklore, believed to be a supernatural substitute left in place of a human child or adult. Such stories formed part of traditional beliefs about contact with the fairy world. They should be understood as folklore rather than supernatural fact, and these beliefs could have tragic consequences for real families.
CHILDREN OF LIR: In one of Ireland's best-known legends, four children are transformed into swans by their jealous stepmother. They spend long periods on lakes and seas, enduring exile before the spell finally ends. Their story has become an emblem of loss, endurance and the relationship between Irish folklore and the natural landscape.
CLADDAGH RING: A traditional Irish ring featuring two hands holding a heart beneath a crown. It is commonly interpreted as representing friendship, love and loyalty and originated in the Claddagh area of Galway. Today, it is an internationally recognised symbol of Irish heritage and is often given as a personal or romantic gift.
CÚ CHULAINN: A legendary warrior of the Ulster Cycle, celebrated for his extraordinary fighting abilities and battle frenzy. Best known for defending Ulster against the forces of Queen Medb in the Táin Bó Cúailnge, he is one of the central heroes of medieval Irish mythological literature.
D
DAGDA: A major figure among the Túatha Dé Danann, associated with abundance, strength, wisdom and supernatural power. His traditional attributes include a great club, a magical cauldron and a harp. He plays an important role in Ireland's medieval mythological literature.
DULLAHAN: A frightening supernatural figure in Irish folklore, usually described as a headless rider carrying his own head or travelling in a dark vehicle. In some stories, his appearance or call foretells a death. Details vary between tellings, reflecting the diversity of Irish supernatural tradition.
F
FAIRY FORT (LÍOS SÍ): An ancient ring-shaped earthwork or other traditional site associated in Irish folklore with the fairy world. Stories often warn against disturbing these places, particularly by damaging a mound or cutting down a lone hawthorn. Many such sites are human-made archaeological structures associated with early medieval settlement.
FIONN MAC CUMHAILL: The legendary leader of the Fianna, a band of warriors and hunters in Irish mythology. His stories include the Salmon of Knowledge and adventures involving supernatural beings and extraordinary landscapes. Fionn remains one of the best-known heroes of Irish storytelling tradition.
G
GIANT'S CAUSEWAY: A remarkable formation of interlocking basalt columns on the north coast of Northern Ireland, created by ancient volcanic activity. Its geological origins are complemented by a famous legend in which the giant Fionn mac Cumhaill builds a causeway across the sea. It combines natural heritage with Irish storytelling.
H
HIGH CROSS: A monumental stone cross, many examples of which date from Ireland's early and high medieval periods. Often decorated with biblical scenes, geometric patterns and interlaced designs, high crosses served religious and commemorative purposes at monasteries and other important sites. They are among Ireland's most distinctive forms of medieval sculpture.
HOLY WELLS: Springs or wells associated with saints, healing, prayer and local pilgrimage. Many Irish holy wells are linked to particular feast days and local legends, and some continue to attract visitors who leave offerings or perform customary prayers. They reflect the close relationship between natural places, religious practice and community identity.
I
IMBOLC: A traditional seasonal festival celebrated around 1 February and associated with the beginning of spring. In Ireland, it became closely linked with St Brigid's Day and customs seeking blessings for homes, farms and animals. Its precise ancient observances are not fully known, but it remains an important part of Irish seasonal tradition.
IRISH DANCE: A group of traditions ranging from social set dancing and céilí dancing to solo step dancing. Styles differ in their footwork, posture, rhythm and purpose. Modern stage performances have introduced Irish dance to international audiences, while community dancing continues to play an important role in cultural life.
IRISH HARPIST'S HARP (CLÁIRSEACH): The harp is one of Ireland's most enduring national emblems and a central instrument in its musical heritage. The design used as the state emblem is based on the medieval-style harp associated with Brian Boru, preserved at Trinity College Dublin. The instrument appears on official state insignia, coins and documents.
IRISH HURLEY AND SLIOTAR: The hurley is a wooden stick used in hurling, while the sliotar is the small ball struck during the game. Together they are strongly associated with one of Ireland's most distinctive traditional sports, which is administered nationally by the Gaelic Athletic Association.
IRISH TOWER HOUSE: A compact fortified residence built throughout Ireland, particularly from the late medieval period into the sixteenth and seventeenth centuries. Many were associated with local landholding families and combined domestic accommodation with defensive features. Their surviving ruins form a distinctive part of Ireland's castle landscape.
IRISH TRICOLOUR: Ireland's national flag, consisting of vertical green, white and orange bands. Presented in the nineteenth century and later adopted by the Irish state, it is commonly interpreted as expressing the hope for peace and unity between different traditions on the island. Its symbolism has not always been understood or accepted in the same way by everyone.
IRISH WAKE: A gathering held around the death of a person, traditionally bringing family, neighbours and friends together to mourn and remember the deceased before burial. Practices have varied across Ireland and over time, with prayers, stories, food and companionship often forming part of the gathering.
IRISH WOLFHOUND: A giant, long-legged dog breed with a long association with Ireland. Historical accounts describe large hounds used for hunting and prized as gifts among elites. The modern breed reflects a later process of revival and breeding, but the wolfhound remains a powerful emblem of Irish canine heritage.
L
LA TÈNE ART: A style of Iron Age European decoration characterised by flowing curves, spirals and stylised plant or animal forms. Related designs influenced objects found in Ireland, although local examples have their own distinctive character. It highlights Ireland's connections with wider Iron Age Europe without suggesting that every interlaced pattern is uniquely Irish.
LEPRECHAUN (LEIPREACHÁN): A small supernatural being in Irish folklore, traditionally associated with shoemaking, mischief and hidden wealth. Older stories are more varied than the familiar modern image of a green-clad figure guarding a pot of gold. His present-day appearance owes much to popular culture as well as traditional storytelling.
LIA FÁIL (STONE OF DESTINY): A standing stone at the Hill of Tara, a site closely associated with Ireland's ancient kingship traditions. In legend, the stone recognised a rightful king, sometimes by crying out when he stood upon it. Its mythological associations are important, but the royal legends should not be treated as entirely documented history.
LUGH: A prominent figure in Irish mythology, renowned for his many skills and abilities. He becomes a key leader among the Túatha Dé Danann in the story of the Second Battle of Mag Tuired. His name is also associated with Lughnasa, the traditional festival marking the beginning of the harvest season.
LUGHNASA: A traditional festival associated with early August and the beginning of the harvest season. Named for the mythological figure Lugh, it was marked in some places by gatherings, fairs and visits to mountains or other significant locations. Its local customs varied, and modern events sometimes revive traditions associated with it.
M
MANANNÁN MAC LIR: A supernatural figure associated with the sea and the Otherworld. In Irish stories, he is linked with magical voyages, mist and objects possessing extraordinary powers. His character varies across the tradition, but his maritime associations make him one of Ireland's most evocative mythological figures.
MERROW: A sea-associated supernatural being in Irish folklore, often described as having human and aquatic characteristics. Some stories portray merrows as women who live beneath the sea, while others describe encounters between merrows and humans. These varied accounts reflect the importance of the sea in Irish storytelling.
MORRÍGAN: A complex figure in Irish mythology associated with warfare, sovereignty and foreknowledge. She appears in stories connected with battles and can take the form of a bird. Her identity and relationships with other supernatural figures vary between texts, so she is better understood as a multifaceted mythological figure than as a simple goddess of war.
N
NEWGRANGE: A prehistoric passage tomb in County Meath, built around five thousand years ago. Its passage and chamber are aligned so that sunlight illuminates the interior around the winter solstice. Its decorated stones and monumental construction make it one of Ireland's most remarkable prehistoric sites, although the precise meaning of its symbols remains uncertain.
O
OAK: An enduring feature of European woodland landscapes, the oak is commonly associated in modern symbolism with strength and longevity. Oak trees also appear in Irish place names and folklore. However, specific claims about a universal ancient Celtic meaning should be treated cautiously unless supported by historical evidence.
OGHAM STONE: A standing stone bearing inscriptions made with groups of strokes cut along its edge. Ogham was used in early medieval Ireland, often to record personal names and family affiliations. These monuments provide valuable evidence for the early Irish language and society and connect the modern landscape with communities that lived more than a thousand years ago.
OISÍN: A poet and warrior of the Fianna and, in later legend, the son of Fionn mac Cumhaill. His best-known story describes his journey to Tír na nÓg with Niamh. When he returns to Ireland, centuries have passed and the world he knew has changed, creating a tale about memory, mortality and the passage of time.
P
POT OF GOLD: A familiar image in Irish-themed folklore and popular culture, usually linked to leprechauns and the end of a rainbow. It is best understood as a popular motif rather than a securely documented ancient Irish symbol. Its enduring appeal lies in the promise of hidden riches, trickery and elusive good fortune.
PÚCA: A shape-shifting being in Irish folklore that may appear as an animal or take other forms. Stories portray it as unpredictable: sometimes helpful, sometimes mischievous or frightening. Its appearance and behaviour vary widely between accounts, making it a distinctive part of Ireland's supernatural storytelling tradition.
R
RAVEN: A dark-feathered bird associated in some Irish mythological stories with warfare, prophecy and the Morrígan. Its intelligence, dark plumage and presence around battlefields made it a striking figure in traditional imagination. The raven is not exclusively Irish, and its significance depends on the particular story or artistic context.
RED HAND OF ULSTER: A historic heraldic emblem associated particularly with the O'Neill dynasty and the province of Ulster. A popular legend tells of a competitor who cut off his own hand and threw it ashore to claim land before his rival. This story is legendary rather than established history, and the emblem has acquired different political and cultural associations.
RINGFORT: A circular enclosed settlement, usually defined by an earthen bank and ditch or by stone walls. Many ringforts date from the early medieval period and are associated with farming households. They remain among the most widespread archaeological features in the Irish countryside.
ROUND TOWER: A tall, circular stone structure characteristic of many early medieval Irish monastic sites. Its exact functions remain debated, but towers may have served as bell towers, landmarks, storage spaces and places of refuge. Their height and narrow entrances make them distinctive features of Ireland's ecclesiastical landscape.
S
SALMON OF KNOWLEDGE (BRADÁN FEASA): A magical salmon from the Fenian Cycle whose flesh grants wisdom. In the best-known version of the story, the young Fionn mac Cumhaill gains extraordinary knowledge after tasting the fish while preparing it for the poet Finegas. The tale is one of the most celebrated episodes in Irish mythology.
SAMHAIN: A traditional festival marking the beginning of the darker half of the year, celebrated around 1 November. Associated with the end of the harvest and the approach of winter, it is linked in Irish folklore with heightened contact between the human world and the Otherworld. Samhain forms part of the background to later Halloween customs.
SEANCHAÍ: A traditional Irish storyteller and keeper of local lore, family histories, legends and tales. Storytelling helped transmit knowledge and entertainment in communities where oral tradition was central. The role could also involve preserving local memory, place names and stories about people and landscapes.
SEAN-NÓS SINGING: A traditional form of Irish-language singing, generally performed solo and without instrumental accompaniment. Its intricate ornamentation, flexible rhythm and regional styles require considerable skill. Rather than being one fixed method, sean-nós encompasses diverse local traditions and remains an important expression of Irish-language cultural heritage.
SHEELA-NA-GIG: A medieval stone carving, usually depicting a female figure displaying her genitals. Such carvings survive on churches, castles and other buildings in Ireland and Britain. Their original purpose remains uncertain, and interpretations include protective, religious or fertility-related meanings, none of which should be treated as a universally proven explanation.
SHILLELAGH: A traditional Irish wooden stick, commonly associated with blackthorn or oak. It could serve as a walking stick and historically as a weapon in personal or factional fighting. Today, it is widely recognised as an emblem of traditional Irish life, although popular depictions sometimes exaggerate its connection with fighting.
SHAMROCK (SEAMRÓG): A small three-leaved plant and one of Ireland's best-known national symbols. It is traditionally associated with St Patrick, who is said to have used its three leaves to explain the Christian doctrine of the Trinity. The story was recorded relatively late, while the shamrock's wider association with Ireland developed over time.
ST PATRICK (NAOMH PÁDRAIG): Ireland's best-known patron saint, traditionally credited with helping spread Christianity across the island during the fifth century. His own writings provide important evidence about his life, while many familiar stories come from later traditions. His feast day, 17 March, is celebrated worldwide as both a religious occasion and an expression of Irish identity.
T
TARA BROOCH: An exceptionally elaborate early medieval Irish brooch, famous for its intricate metalwork, animal ornament and fine decoration. Despite its name, it is not securely linked to the Hill of Tara. It represents the high level of craftsmanship achieved in early medieval Ireland and the importance of personal ornaments as objects of status.
TORC: A rigid or semi-rigid metal neck ring worn in ancient Europe, including by communities associated with Iron Age Celtic art. Some examples are made of twisted metal, while others feature elaborate decoration. Torcs discovered in Ireland demonstrate the skill of ancient metalworkers and were probably associated with status in certain societies.
TRIQUETRA: A three-cornered interlaced motif found in historic and modern decorative art. It appears in a range of artistic and religious contexts and is frequently interpreted today as a symbol of eternity or interconnectedness. Its original meaning was not necessarily the same in every period or culture.
TRISKELE (TRIPLE SPIRAL): A three-part spiral motif found in prehistoric and later European art. One of Ireland's best-known examples appears among the carvings at Newgrange. Although the design is often interpreted as representing cycles or movement, its precise prehistoric meaning remains unknown.
TÚATHA DÉ DANANN: A supernatural people in Irish mythology, associated with extraordinary skills and powers. They feature prominently in medieval stories about Ireland's mythological past and include figures such as the Dagda, Brigid and Lugh. Their stories combine supernatural conflict, kingship and the origins of important cultural traditions.
U
UILLEANN PIPES: Ireland's distinctive bellows-blown bagpipes, played using a bellows beneath the arm rather than by blowing directly into the bag. They allow intricate melodies, ornamentation and accompaniment and are a major instrument in traditional Irish music. Their expressive range makes them particularly distinctive among European bagpipe traditions.
About
Hello, and welcome to Castles of Éireann! Or, as the Irish would say, Tá sé go deas bualadh leat.
Perhaps the best way to tell you who we are is to tell you how this website began.
It all started one October day when we, having both arrived in Ireland independently for work, found ourselves beginning a new chapter of our lives. We had made our way to different parts of the country: Andreea to Dublin and Pasquale to Limerick. Neither of us knew at the time quite where that journey would take us. We certainly did not imagine that, years later, Ireland would feel like home.
Our fascination with Irish castles began rather innocently. One quiet Sunday, with no particular plans and wondering where to go, we opened Google Maps and noticed the ruins of Carrigogunnell Castle, just outside Limerick. We went there simply because it looked interesting. We had no idea that this rather unremarkable Sunday outing would become the beginning of something much bigger.
Since then, castles have taken us all over Ireland. We have discovered magnificent fortresses, forgotten tower houses, ruined estates and places that are barely marked on a map. And the more we explore, the more we realise that what fascinates us is not simply the buildings themselves. It is everything around them: their architecture, their landscapes, the people who once lived there, the stories and legends connected to them, and the historical events that shaped the Ireland we know today.
There is something particularly captivating about standing among the ruins of a place that was once full of life and power. Walls that once stood strong are slowly returning to the landscape; rooms that once echoed with voices are now silent. It is almost impossible not to wonder what these places looked like centuries ago, when their courtyards were busy, their fires were burning and their inhabitants had no idea that one day only fragments of their world would remain.
Sometimes, wandering through these ruins, we find ourselves imagining another life entirely: that of long-forgotten lords, perhaps dispossessed earls walking alone through what was once their home, trying to reconstruct in their imagination the world that had disappeared around them. Perhaps that is part of the magic of these places. They leave just enough behind for the imagination to take over.
Andreea comes from Romania, a country of castles, fortresses and legends. With a background in journalism and a passion for photography, she is fascinated by architecture, history, nature and the stories hidden behind the places we visit. She is particularly interested in capturing not only what a castle looks like, but also something of the atmosphere surrounding it. She is also firmly convinced that Castles of Éireann needs a drone. We are still negotiating.
Pasquale is an electronic engineer from Italy, with a particular interest in politics and a tendency to take things apart mentally to understand how they work. History naturally fits into that way of thinking: he enjoys looking beyond events and trying to understand the forces, decisions and circumstances that shaped them. He also enjoys reading, listening to people and discovering different points of view. Perhaps unsurprisingly, this means that a simple question rarely remains a simple question for very long.
Between us, we normally speak Italian. When a conversation becomes particularly heated, however, we switch to English and return to neutral ground. It seems only fair.
Of course, exploring Ireland's ruins is not always as romantic as it sounds. We have crossed muddy fields, walked through gorse, been soaked by Irish weather, received electric shocks from fences and had quite a few encounters with dogs. Most of the dogs have been perfectly friendly. The cows have been a different matter.
Once, in Galway, a landlord kindly gave us the keys to a castle and warned us that there would be cows around the property. He assured us that they were gentle. We closed the gate behind us and went off to explore. When we were ready to leave, we discovered that several dozen cows were waiting outside the gate. After about half an hour of staring at one another, we decided that diplomacy was worth a try. We explained to them that there was no need to worry because we were perfectly harmless. We even pointed out that Pasquale was a vegetarian and suggested that, if they had any complaints, they should take them up with Andreea. The cows remained unconvinced.
Eventually, we decided on a tactical withdrawal. We would leave the gate, walk around the castle and approach the road from the other side. We set off, turned the corner... and found another group of cows waiting for us. So we ran back. It took us hours to get out of there.
On another occasion, in Tipperary, a landlord encouraged us to walk onto his property because the view of the tower house was better from behind it. While we were taking photographs, Andreea suddenly spotted four or five horses approaching from behind Pasquale. We ran for the gate. Thinking that Andreea was right behind him, Pasquale tried to position himself between her and the horses. When he turned around, however, she had disappeared. She had thrown herself into the gorse and was making her own escape. We both eventually made it back to the gate. And somehow, we still visit castles. After all that, the landlord mocked us for being unable to handle his horses. We were not entirely convinced that this was the right moment to discuss our equestrian skills.
But Castles of Éireann was never meant to be simply a catalogue of places we have visited. In many ways, it is a gift to ourselves. When work has been particularly difficult, we can take a break, open the website and choose a castle. We look through the photographs, revisit places we have already explored and, for a little while, allow ourselves to be somewhere else.
At the same time, we wanted to share that feeling with people around the world who are curious to discover a quieter, more hidden and authentic side of Ireland. There are said to be tens of thousands of castle ruins, tower houses and other historic remains scattered across Ireland. A lifetime would not be enough to see them all, let alone document them. So we have made peace with the fact that this website will probably never be finished. And that is perfectly fine.
We will keep adding new castles, photographs, stories and historical research, little by little, as our own journey through Ireland continues. Perhaps, over time, Castles of Éireann will also become a place where other people who share our fascination with Irish history can contribute their own knowledge, memories and discoveries. Perhaps you will discover a castle here that you have never heard of. Perhaps you will know something about one of these places that we do not. Perhaps you will simply enjoy wandering through the site as much as we enjoy building it.
If so, GET IN TOUCH. Tell us about a castle we should visit, share a story, correct us if we have got something wrong, or simply let us know that you enjoyed the journey.
There are far too many castles in Ireland for two people to discover them all. So we might as well enjoy the journey. And if you happen to know where the next one is, even better.
Our own journey began almost by accident. A few years ago, on a warm summer day, we came across the ruins of Carrigogunnell Castle, near Clarina in County Limerick. We knew very little about it when we arrived. We certainly did not expect that a ruined medieval castle, standing quietly above the Shannon valley, would become the starting point of something that would accompany us for years.
That curiosity gradually became Castles of Éireann.
