Ballyloughan Castle was probably built in the 13th century and consisted of a large open courtyard with a curtain wall and a moat outside. Only a small square tower of Ballyloughan Castle remains, as well as the entrance gate which is flanked by two large rounded towers.
Ballyloughan Castle originally belonged to the Kavanaghs before passing into the hands of the Bagenal family of nearby Bagenalstown and following this the Bruen family in the early 19th century.
No access allowed. The castle may be viewed from the nearby adjacent gate.
