Hen's Castle or Caislean-na-Circe located on Lough Corrib between Maam and Doon. The castle was home of the great pirate Queen of Connemara, Grace O`Malley, who lived in the time of Queen Elizabeth 1 of England. The Lord Justice, in 1225, caused Odo O'Flatherty to give up Kirk Castle to Odo O'Connor, King of Connaught; for assurance of his fidelity.Caislean na Circe (built in a night by a cock and a hen according to legend) is one of the oldest mortared castles in Ireland. This Norman keep, placed in the direction of the cardinal compass points, was built early in the 12th Century by the sons of Roderick O'Connor, last High-King of Ireland, aided by their then ally, William Fitz-Adelm, the first de Burgo (later Burke). This castle which occupies almost the entire island had a troubled history, being stormed and besieged many times, not the least of which was the celebrated occasion when Grainne Mhaol (Grace O'Malley) personally defended it. It continued to be occupied as a castle until it finally succumbed to the Cromwellian soldiers in 1654.
