From Wikipedia: The castle was originally a basic, multi-storied Irish tower house which was built circa 1480,
probably by Toirdelbhach Donn MacTadhg Ó Briain, King of Thomond, one of the last of the High Kings of Ireland and a direct descendant of Brian Boru.
The castle's name "Leamaneh" is believed to be derived from the Irish "léim an éich" which, when translated into English means "the horse's leap".

It is located at the corner of the R476 and R480, NW of Ennis.
