Church of St Michael

The Church of St Michael is a Romanesque church built of stone rubble, originally lime rendered, with ashlar dressings and a Welsh slate roof. The church's plan includes a nave, a north aisle, and a north porch. The north side faces the churchyard, while the west and south sides are within the grounds of Ewenny Priory House. The eastern end adjoins the priory crossing and chancel, which are in separate ownership.

The gabled north porch features a wide, roll-moulded four-centred arched doorway, topped by a square-headed hoodmould. The segmental arched inner doorway has hollow chamfers stopped at its base, lacking capitals. The clerestory on the north and south sides has three long, narrow round-headed windows. The north aisle windows are triple (east) and quadruple (west) round-headed lights with hollow chamfers set within a square-headed frame with a hoodmould. The south side has a two-light square-headed window above a Romanesque doorway at the southeast end of the nave, which historically served as the monks' processional entry, adjacent to a similar doorway leading into the priory’s south transept. This doorway has two orders; the outer order exhibits strong billet moulding with plain imposts. The west end was refaced with slate in the early 19th century.

The churchyard to the north is enclosed by a low rubble wall, with an iron lamp arch to gate piers at the northwest entrance.

Inside, the walls are lime-plastered, with exposed dressings. The nave is tall, with deep splayed clerestory windows above spandrels to the south and north arcades. The four-bay north arcade has massive cylindrical piers with plain, unchamfered double-order arches, moulded plinths on square bases, and fluted capitals. At the southwest corner, a section of a blocked window is visible, where the west wall was rebuilt. At the northwest arcade, the arcade stops short of the west wall. A deep recess is present in the middle pier, and grooves are visible on others. Aisle windows have deep hollow chamfers, diamond quarries, and iron armatures; the northwest window has two four-centred arched lights in a square frame, while the southeast window features a square-headed window with a damaged mullion, rectangular quarries, and an armature. The chancel arch also has two orders, with a pair of attached half-round columns with lightly scalloped capitals. Below this is a pulpitum, with blocked pointed arched doorways at the north and south sides—the former with an inner order—above which is a partition separating the church in use from the east priory church. A round arched doorway with a hood mould is situated at the northeast, with some medieval tiles on the floor at this location. A tall round-headed doorway is found on the east end of the south wall, leading to the former monastic range. The nave has a stone floor, rising one step to the present sanctuary, which is floored with ledger slabs. The boarded nave roof has been replaced, with corbels on the north aisle roof indicating a former different roof pitch. This repair work to the nave and rebuilding of the aisle by Thomas Picton Turbervill is recorded on a metal inscription plaque. The font is chalice-shaped, with narrow roll moulding on a splayed base and no stem. There are modest 18th-century wall monuments and a memorial to those who served in the First World War. The nave door retains some old metal fittings.
