Doonagore Castle

Doonagore Castle is a round 16th-century tower house with a small walled enclosure located about 1 km above the coastal village of Doolin in County Clare, Ireland. Its name may mean "the fort of the rounded hills" or the "fort of the goats"; it sits on a hill overlooking Doolin Point and, along with a nearby higher radio mast, is used as a navigational point by boats approaching Doolin Pier. Doonagore Castle is at present a private holiday home, inaccessible to the public.

While a castle was built on the site by Tadgh MacTurlough MacCon O'Connor from stone drawn from the quarry of Trá Leachain some time during the 14th century, the current structure is likely to date to the 16th century. It was granted to Sir Turlough O'Brien of Ennistymon (a neighboring town of Doolin) in 1582.
