Ballymalis Castle is a partially restored tower house and National Monument located in County Kerry near Beaufort, standing 16.8 metres high on the north bank of the River Laune. Built in the early sixteenth century by the Ó Muircheartaigh family, the castle was renovated by the Ó Fearghuis clan in the late sixteenth century. Featuring rectangular construction with four storeys, an attic, and bartizans at the southwest and northeast corners, the fortification was confiscated in 1677 and subsequently granted to the Eager family. The castle's walls measure 2.5 metres thick, reflecting its strategic importance in medieval Kerry.
