Overview
Rising from the sparkling waters of Lough Corrib, Ireland’s largest lake, Castlekirk – popularly called Hen’s Castle – dominates a tiny half‑acre island in the lake’s north‑west corner. The stone keep, now a romantic ruin, stands four storeys high and is a National Monument under the guardianship of the Office of Public Works (OPW). Because the island is reachable only by boat, the castle retains an air of isolation that has helped preserve its mystique and makes it one of the most photographed historic sites in County Galway.
History
Early origins
The castle’s foundations date to the early 12th century, making it one of the oldest mortared tower houses in Ireland. It was erected by the sons of Ruaidrí na Saide Buide, a Connacht king, with assistance from the Anglo‑Norman lord William FitzAldelm. The original structure was a rectangular keep with thick limestone and sandstone walls, a vaulted ceiling, a spiral stair, and a fireplace – typical of early Norman fortifications.
Shifting allegiances
Its strategic position on Lough Corrib meant the keep changed hands repeatedly. In 1225 the Lord Justice Sir Edmond Butler forced the local chieftain Odo O’Flaherty to surrender Castlekirk to Aedh Ua Conchobair, King of Connacht, as a token of loyalty. Eight years later, in 1233, the castle was razed by forces loyal to Hugh de Lacy, Earl of Ulster, and promptly rebuilt by Fedlimid, son of Cathal Crobhdearg Ua Conchobair. Throughout the 14th century the O’Flaherty clan reclaimed the keep and held it for several generations.
The pirate queen and the Hen’s Castle legend
The most colourful chapter arrived in the mid‑16th century when the legendary pirate queen Gráinne Ní Mháille (Grace O’Malley) married Donal an‑Chogaidh O’Flaherty, nicknamed “the Cock”. After Donal’s murder by the rival Joyce family in 1565, Gráinne stormed the fortress, killed the Joyce leader and secured the stronghold for herself. From that moment the site became popularly known as Hen’s Castle, a tribute to both the pirate queen (the “Hen”) and her late husband (the “Cock”).
The castle remained a functional stronghold until it fell to Cromwellian troops in 1654. In the 19th century local builders stripped many of its stones for house‑building, leaving the ruin that visitors see today.
Legends & myths
Folklore adds another layer of intrigue: a tale tells of a witch who enlisted a cock and a hen to ferry stones from the lake shore to the island, helping the O’Flahertys fortify the keep.
What to See & Do
- Photographic silhouette – The stark, four‑storey tower against the lake makes a dramatic subject at sunrise or sunset.
- Stonework details – Observe the surviving limestone walls, square corner towers and the remnants of the original vaulted chambers.
- Lake scenery – The surrounding waters are rich in wildlife; keep an eye out for swans, ducks and the occasional otter.
- Folklore storytelling – Use the legends of the witch, the cock and the hen as a backdrop for a memorable narrative when sharing photos or guiding a small boat party.
Because the island is closed to public entry, the experience is limited to viewing the ruin from the water and appreciating its setting from a boat.
Getting There & Boat Tours
- Private boat – The most flexible option is to launch a private craft from a slipway at Cong or from the Lough Corrib Visitor Centre. Both locations provide short‑term parking and basic facilities.
- Local water‑tour operators – Several operators in Cong and the surrounding villages run short guided trips that circle the island, offering commentary on the castle’s history and the lake’s wildlife. (Names and timetables vary seasonally; check locally before you travel.)
- Permission to land – The island is a protected National Monument. Landing is only allowed with explicit permission from the OPW, which is rarely granted to the general public.
- Dog‑friendly – Dogs are welcome on board the boat, but they must remain leashed and are not permitted on the island itself.

Photography Tips
- Golden hour – Early morning or late afternoon light brings out the warm tones of the stone and creates striking reflections on the water.
- Telephoto lens – A 70‑200 mm lens lets you fill the frame with the tower while staying safely on the boat.
- Polarising filter – Reduces glare on the lake surface and deepens the sky’s colour.
- Safety first – Keep the camera dry; a waterproof bag or rain cover is advisable when shooting from a moving boat.
