A small rectangular church with antae at the W end. The W wall survives to a height of 2.15 m above current ground level, the S wall remains at close to its original height. All other walls are destroyed to foundation level. The church is situated within surrounding earthworks, the ground level has risen greatly around it due to modern burials.

The early monastic foundation is attributed to St. Cairneach of Cornwall. A stone church was burnt during Viking raids at the site in 920. The site was plundered by Dermot Mac Murrough in 1170. The church at Dulane became a parish church shortly after the Anglo-Norman invasion.

Trabeated doorways with carved architraves are also found at Glendalough (St. Mary's and Reefert) and at Fore. The form of the doorway combined with the moulding profile is suggestive of an early 12thc. date.
