This coastal fortification, likely built in the 15th or 16th century, was strategically positioned to oversee Galway Bay and protect the surrounding territory. Though now partially ruined, its remaining stone walls and distinctive corner towers still command an impressive presence against the Atlantic backdrop, making it a compelling destination for those interested in Ireland’s tower house tradition.

The castle’s history is intertwined with the powerful O’Flaherty clan, who controlled much of Connemara during the medieval period. Like many Irish tower houses of its era, it served dual purposes; both as a defensive stronghold and as a symbol of the family’s status and authority in the region. The structure follows the typical design of Irish tower houses, with thick limestone walls that would have originally supported multiple floors connected by a spiral staircase, and narrow windows that provided both light and defensive advantages during times of conflict.

Today, the ruins at Oran More stand freely accessible to visitors, though care should be taken when exploring the uneven terrain and weathered stonework. The site offers spectacular views across Galway Bay towards the Burren and the Aran Islands, particularly striking at sunset when the limestone walls glow in the evening light. For those travelling the Wild Atlantic Way, this lesser-known castle provides a peaceful alternative to busier tourist sites, where you can contemplate centuries of Irish coastal history whilst listening to the waves crash against the shore below.
