The church consists of nave and chancel, 16.15 m x 6.55 m and 8.53 m x 6.4 m respectively (Westropp). The W wall and W end of the nave are in ruins with only the lower walls remaining. The E end is standing but is heavily overgrown with ivy. There are 12thc. windows in the E and S walls of the chancel, these are tall and narrow with a wide splay on the interior. The S window of the chancel is round-headed with a broad hollow chamfer on the exterior. The E window has a simple chamfer on the exterior. There are two later medieval windows in the S wall of the nave. The chancel arch has a plain square arch of one order, with a slight arris roll on the jambs. There is a late Romanesque S doorway at the W end of the nave.

Early monastic site. Founded by St Mogua, date and identity uncertain (Westropp, 1900b,133).

The chancel arch is 12thc., and earlier than the S doorway, which has decoration similar to Corcomroe Abbey, and is probably early 13thc. Westropp dates the early church to the 10th or 11thc. (much repaired), and mentions ancient heads of E and S windows.
