Castlekirk (Hen’s Castle)

Discover the majestic island castle on Lough Corrib

Welcome to enchanting Castlekirk, also known as Hen’s Castle, a captivating tower house that stands proudly on a half-acre island in the stunning Lough Corrib in Co. Galway. Steeped in history and legend, this ancient fortress has a tale to tell like no other.


Dating back to the early 12th century, Castlekirk is believed to be one of Ireland’s earliest mortared castles. It was skillfully constructed by the sons of Ruaidr na Saide Buide, along with William FitzAldelm, and has witnessed centuries of dramatic events.

In 1225, the Lord Justice Sir Edmond Butler played a pivotal role in Castlekirk’s history by compelling Odo O’Flaherty to surrender the castle to Aedh Ua Conchobair, the king of Connacht. The fortress faced destruction in 1233, only to be valiantly rebuilt by Fedlimid, the son of Cathal Crobhdearg Ua Conchobair.

But the intrigue doesn’t end there. Legend has it that the renowned Gráinne N’Mháille, also known as Grace O’Malley, bestowed the name “Hen’s Castle” upon it in 1546. This fiery pirate queen married DĂłnal an-Chogaidh O’Flaherty, nicknamed “the Cock” for his aggressive nature, and she was playfully called “the Hen.” After her husband’s tragic demise at the hands of the Joyces, Gráinne fiercely recaptured the castle, immortalizing its name.

Yet, the legends don’t stop with historical figures. According to local lore, the O’Flaherty family enlisted the help of a witch to weave her magic while a cock and a hen magically erected the castle. A truly fantastical tale!

Throughout its existence, Castlekirk endured various phases, including occupation by Cromwellian soldiers in 1654. Sadly, in the 19th century, the castle suffered further vandalism as its stones were pilfered to build neighboring homes.

Today, Castlekirk’s keep may be in ruins, but its majestic presence and rich history continue to draw visitors from far and wide. Standing on the shores of Lough Corrib, it whispers tales of legendary figures, fierce battles, and mystical wonders of the past. So, next time you find yourself near Galway, make sure to hop on a boat and explore the magical allure of Castlekirk Castle on Lough Corrib!
