Ballyadams Castle is a fifteenth-century fortified house near Ballylynan in County Laois, historically the seat of the O'More family, a leading sept of the Seven Septs of Laois. The small but tall structure spans approximately five floors with an unusual multi-period plan, featuring an almost completely intact twin-towered entrance and portions of the original keep. Built to control territorial power in the region, the castle has witnessed significant historical events including the 1346 attack by Gaelic clans and its seizure during the 1534-1537 Silken Thomas rebellion. Tours can be arranged in advance through the Laois Heritage office.
