What makes the site quietly arresting is not its ruination but its relative completeness: three of the four walls still stand to their full original height, which is unusual for a structure of this age and exposure. Only the east gable has been substantially lost to time.

The building is a rectangular medieval parish church oriented east to west, measuring 15.4 metres in length and 7.1 metres in width. It is dedicated to Saint Columbkille, also known as Columba, the sixth-century Irish monk associated with the monastery of Iona in Scotland and with numerous churches across the north and west of Ireland. Architecturally, the most legible surviving feature is a pointed arch doorway set towards the western end of the south wall; pointed arches of this kind are typical of medieval ecclesiastical construction in Ireland and indicate some degree of Gothic influence. Internally, at the eastern end of the same wall, there are traces of a blocked window opening, suggesting the interior was once lit differently than its current shell implies. A reference in O'Flanagan's 1927 survey places this site within a broader landscape of medieval settlement and activity. That context is reinforced by the proximity of a castle, the remains of which stand just 70 metres to the north-east, on the opposite bank of the River Clare. The pairing of a parish church and a nearby castle across a river is a configuration that appears often in medieval Irish landscapes, where ecclesiastical and secular authority occupied adjacent but distinct ground.
