Further south, on the banks of the River Shannon, is the site of Castle Donnell or Cratloemore Castle, though now little of the ruins are left. This was once one of the biggest castles in Cratloe, being used by the McNamaras as a trading post because of its location on the River Shannon and its proximity to both Bunratty and Limerick. In 1730 most of this castle was destroyed and the stones were used to build Cratloe Wood House, the only example of an Irish longhouse still lived in by a family.
