A single cell church (25.9 m x 7.26 m) constructed from roughly coursed basalt with limestone detailing. The church has doors in N and S walls, an E window of 17thc. date and two narrow-headed lancets in the N wall. The aumbry, in the S wall, is richly moulded and dates to the early 13thc. The entire church was used for worship until 1827, when the nave was shortened to 16.15 m. The remaining section of the nave was left unroofed. It ceased to be used for worship in 1842.
Nothing is known of the early history of the site.
Located 0.76 m from the interior SE angle of the church. The aumbry is round-headed with a continuous moulding comprising a triple roll between two hollows.
