Castle

Situated in woodland c. 25m from the E shore of Lough Rinn, which is described as ‘Clam Lough’ on the Down Survey (1656-8) barony map where the castle is depicted as what might be two towers. The house of Mael Sechlainn MacRaighnaill was attacked by Tadhg MacRaighnall in 1473 when fourteen men were killed (AC), and this is thought to be at Lough Rinn (Mc Carthy 1989-90, 126). It is described as a castle ruin on an estate map (Wogan 1750, 22), and the terrier or commentary suggests that it might be easily repaired. This might have been done as the remains have been conserved. The castle is a rectangular structure (ext. dims 10m N-S; 7m E-W) with battered walls and rounded corners, surviving to H of c. 7m, except for much of the S and E walls (H 1.5-3m; T 2m). A destroyed doorway (Wth 0.8m) towards the W end of the S wall leads through a lobby to the ground floor, which has the remains of an E-W barrel vault and a simple light in every wall except the S. A mural stairs rises eastwards from the lobby. The structure was illustrated by Daniel Grose in the late eighteenth century (Stalley 1991, 184-6).

The castle at Rinn was likely held by the House of Mael Sechlainn, an important medieval Irish dynasty, during the 13th to 15th centuries. It is remembered for its strategic location near Lough Rinn and as an example of Gaelic Irish castle architecture in a woodland setting.
