The present Strancally Castle was built by John Kiely in the early 19th century in a Gothic style. The original castle was situated a few miles downriver and the ruins remain. It was built by the Fitzgeralds and is referred to in 1571.
In
1586 the castle was granted to Sir Walter Raleigh and by 1640 it was in the
possession of John Gillard. It was
attacked by Lord Castlehaven in 1645 and it eventually became the property of
Richard Boyle, the Great Earl of Cork. The
ruins consist of a tower house and an adjoining hall.
