In Irish, Thurles or Durlas Éile means Strong Fort of Éile, or, more correctly, Durlas Éile Uí Fhogartaigh (Strong Fort of the O’Fogarty’s of Éile). It is the O’Foragtys that gave their name to Thurles. Cornelius O’Fogarty, the former owner, fought in 1690 at the Battle of the Boyne and was Captain on the side of James II. He owned and played the O’Fogarty Harp. The harp is on the town’s coat of arms.The more recent history is equally as important. The castle was used as a base by Northampton Regiment against the IRA during the turbulent years of the battle of independence. In 1922, as it drew to a close, the castle was burnt and destroyed by the IRA. Today, the ruin of Castle Fogarty still stands, albeit with an impressively renovated residence that stands at the wing of the castle.
