Aughnanaure Castle is an early sixteenth century tower house beautifully situated on the banks of the Drimneen River, flowing into the western side of Lough Corrib close to the village of Oughterard, Co. Galway. Once the medieval residence of the O'Flahertys - the Gaelic lords of Iarchonnacht, it's Connemara’s only surviving intact medieval castle. Today it is open to visitors on a seasonal basis.
