Leamaneh Castle is a ruined castle located in the townland of Leamaneh North, parish of Kilnaboy, between the villages of Corofin and Kilfenora at the border of the region known as the Burren in County Clare, Ireland. It consists of a 15th-century tower house and a 17th-century mansion. Name 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" or léim an fheidh ("the deer's leap"). It is also sometimes spelled "Lemeneagh Castle". Location The castle is located at an important local crossroads and the place where the Baronies of Burren, Corcomroe and Inchiquin met. Today the road R476 from Kilfenora to Kilnaboy village and the R480 north to Ballyvaughan intersect there. History Early structure The castle was originally a basic, 5-storied Irish tower house which was built circa 1480-90, probably by Toirdhealbhach Donn Ó Briain of the O'Brien family, one of the last of the High Kings of Ireland and a direct descendant of Brian Boru.

Her father was Sir Torlach Rua MacMahon, Lord of Clonderlaw and her mother was Lady Mary O'Brien, daughter of the third Earl of Thomond. Her first husband, Daniel O'Neylan (also sometimes written O'Neillan or Neylan) of Dysert O'Dea Castle in north Clare died young and upon his death, she gained control of his substantial estate and a £1,000 fortune. This wealth enabled her and Conor to build a more comfortable mansion on to the tower house. Part of the tower house was demolished and replaced by a 4-storied mansion around 1648. Máire accompanied her husband on raids against English settlers. In 1651, he was mortally wounded fighting on the Royalists' side at Inchicronan (Crusheen).
