}} To the south of Crookstown village is the ruin of the 16th century Clodagh Castle, once home to one of the branches of the McSweeney clan. Another ruined castle, Castlemore Castle or Dundrinan Castle, lies to the north of the village.
Crookstown Road railway station, located close to Castlemore Castle approximately 2 km from the village centre, operated as a stop on the
Cork and Macroom Direct Railway from 1866 until services on the line ceased in the 1940s. The
Irish Republican Army (IRA) was active around Crookstown during the
Irish War of Independence, and Crookstown House, an estate house owned by the
Warren family was
burnt-out by the IRA in June 1921. It was later rebuilt. According to biographer
Tim Pat Coogan,
Michael Collins was likely on his way to a meeting in Crookstown when he was killed in an ambush at nearby
Béal na Bláth during the
Irish Civil War. ==Geography==
