CASTLES IRELAND

Sleady Castle was built in 1628 by Philip McGrath in Jacobean architectural style near Cappoquin in County Waterford, reportedly as a worthy residence for his wife Catherine le Poer of Curraghmore. The McGraths were substantial landowners, controlling over 800 acres by 1654. The castle reflects the period when the clan held significant influence in southeast Ireland, though they were dispossessed by the English Crown around 1640. Much of the castle's remains have been incorporated into a modern house now in private hands, preserving this 17th-century fortress's distinctive heritage within contemporary structures.

Castlelough Castle, also known as McCarthy Mor Castle, sits on a low promontory in Lough Leane near Killarney, County Kerry.

The castle remained with the MacCarthy family until the mid-18th century when it was sold to British colonel William Crosbie, by which time it had already begun its decline into ruin. The site remains historically significant as a focal point of medieval Gaelic and Anglo-Norman power struggles in Kerry.

Built in the late 15th century as the stronghold of the O'Flaherty Gaelic lords, the castle features an unusual double bawn defensive structure unique among Irish castles. The name derives from Irish 'Achadh na nlubhar', meaning 'the field of the yews', reflecting the landscape's natural character. Abandoned for centuries before restoration by the Office of Public Works in the 1960s, Aughnanure now welcomes visitors from March to November, offering a tangible connection to the O'Flaherty clan's two-century dominion over West Connacht and the castle's pivotal role during the Cromwellian invasion of 1652.

Cú Chulainn's Castle, also known as Dun Dealgan Motte, stands on a ridge overlooking Castletown River near Dundalk, blending medieval military architecture with ancient Irish mythology. The Norman motte-and-bailey fortification, built around the 12th century, was later crowned with a tower house known as 'Byrne's Folly' in the 18th century, creating a layered historical structure spanning multiple centuries. The site is profoundly significant in Irish tradition as the legendary birthplace of the mythical warrior Cú Chulainn, with local folklore claiming that an enormous stone in the adjacent field was thrown there by the hero in a supernatural feat of strength.

Built for the Earl of Pembroke in the late 12th century as a symbol of Norman military and administrative control, the castle was extensively rebuilt, extended and adapted over 800 years to reflect changing dynastic needs and architectural fashions. The Victorian-era remodelling created an elegant country house setting, with restored interiors showcasing 1830s splendour, a magnificent picture gallery, library, drawing room and period bedrooms set within extensive parkland.

The castle's distinctive L-shaped fortified manor features a tall round crenellated tower at its southeastern corner, with ground-level chambers that probably served defensive and administrative functions during the medieval period. The name derives from Irish 'Fiodh Ard' meaning 'high wood', reflecting the landscape's natural character, while the castle's history as a episcopal refuge and later private residence of the Loftus family demonstrates its significance through Ireland's turbulent centuries until gradual abandonment by the Irish Civil War era.
