Only the W end of the church and a short section of the adjacent N and S walls still stand. A rectangular splayed window, probably late medieval, survives in the S wall and this incorporates a 12thc. voussoir. The ruin is on a small hill and stands a few metres NE of a souterrain.
Gwynn and Hadcock record that there was an early Irish monastery at Achonry, founded in the 7thc. by St Finian of Clonard. However, this does not refer to Church Hill, but to another site in Achonry which is now dominated by a modern cathedral. A loose stone carved with a 12thc. beast head was discovered there in 2003.

A voussoir from a 12thc. arch has been reused as part of the masonry of the left splay. The voussoir is shallow-carved with a row of beading, followed by a row of zig-zag with beads in the triangles, and then a band of cable moulding. Of coarse red sandstone.
