Ballincollig Castle is a Norman fortification positioned on a rocky limestone outcrop south of Ballincollig town in County Cork, dating to at least the fifteenth century. The castle comprises a curtain wall encircling the rock face with a central slender keep tower. Originally acquired by the Barretts in 1458, it served as their principal stronghold until the early seventeenth century. After capture by Cromwell's forces in 1644 and subsequent disuse following 1690, the keep was restored by the Wyse family in 1857. Today the private structure remains viewable from the roadside.
