The authentically restored 15th century Dysert O’Dea castle, the stronghold of the O’Dea clan, houses the Clare Archaeology Centre which was opened in July 1986 and has been the recipient of numerous national awards.

The Dysert O’Dea Clan is a registered member of the Clans of Ireland.

The O’Dea clan came originally from County Clare where there is a fortified tower house over 500 years old known as O’Dea Castle at the 80-acre (320,000 m²) townland of Dysert O’Dea (Irish: Dísert, meaning “hermitage”).

Indexes to the O’Dea Clan Archives are available for online access to financial members of the Dysert O’Dea Clan Association.
