OS Map Ref: Sheet 29.


Traditionally known as a castle of the MacSheehys, who were gallowglasses brought into Limerick by the earl of Desmond around 1420.
However, it is claimed that Ballyallinan was built by the O’Hallinans, but this was dismissed by another as ‘a mere guess from the name’.1

Ballyallinan is a 15th century rectangular-shaped tower house.

Interesting architectural features: there are box machicolations, or bartizans on the fifth floor level at the east and west corners.


Parts of the walls are damaged and one box machicolation is destroyed (see Image Gallery for both views). The entrance is sealed.


The castle is on private land. Permission is required.
