Moorstown Castle

Moorstown Castle is a late 15th-century stone structure consisting of a circular keep and walled courtyard or bawn. The circular tower house is unusual in Irish architecture, most tower houses being square. It was built by James Keating, an ally of the Earl of Ormond. The castle and associated lands passed to Robert Cox in 1635 and by marriage to the Greene family. It was bought by Richard Grubb through the Landed Estates Court in 1855. The property remains in private ownership.
