O'Dea Castle, also known as Dysert O'Dea Castle is a fortified tower house standing about fifty feet in height about three miles (5km) south from Corrofin/Cora Finne just off the R476 road on the southern edge of the Burren (Irish: Boireann) in County Clare, Ireland (Irish: Contae an Chláir, Éire). The castle was built between 1470 and 1490 by Diarmaid O'Dea, Lord of Cineal Fearmaic. The castle houses the Clare Archaeology Centre which as well as providing tours of parts of the building and surrounding historical monuments also has artefacts from the area dating from 100BC and 1700AD.
