What stands here, on a gently south-facing slope overlooking the broader monastic complex, is a conserved nave and chancel church whose identity has been equated with a Premonstratensian abbey, a reform order originating in twelfth-century France, dedicated to St John the Baptist and recorded under the Latin title 'de Cella Parva', meaning 'of the small cell'. The association with women's religious life may not be entirely wrong, however; it is thought the abbey, established before 1224, may have been founded on the site of an earlier nunnery.

The fabric of the building itself tells a quiet story of change over time. The nave, measuring roughly fifteen metres in length, appears to predate the shorter chancel attached to its east end, suggesting the church grew in phases rather than being conceived as a single structure. Today only the north and south walls of the nave survive to their full height; the west gable and the chancel arch have been reduced to foundations, and of the chancel proper almost nothing remains above ground except a fragment of the east gable at its north-east corner, which preserves part of the embrasure of an east window. Inside the nave, traces of an internal dividing wall near the west end point to a domestic arrangement, residential quarters lit by two small rectangular windows set one above the other in the north wall. A late medieval pointed arch doorway sits just to the east of this partition, and further openings in both the north and south walls of the nave, some possibly doorways, suggest the building saw repeated adaptation across its working life. The accumulated result is a ruin whose ground plan rewards careful reading, each wall and fragment belonging to a slightly different moment in a long institutional history.
