Churchyard boundary walls, including East Lychgate, at Church of St Mwrog

The churchyard boundary walls, including the East lychgate, at the Church of St Mwrog are constructed of large blocks of random stone, forming a high wall to the south that faces the road. The coping is made of intermittent random stones. On the west and north sides, there is a high battered retaining wall of random stone, supported by raked buttresses. The top of the wall on the west side is partly coped in concrete and steps down towards the north. Narrow iron railings surmount the west and north walls. The eastern boundary is mainly marked by a building that is not associated with the church.

The East lychgate is half-timbered, resting on a high stone plinth and covered by a slate roof. It features gabled entrances, with the external east front accessed by steep stone steps. The entrance has a segmental arch, with the lintel supported by timber posts. This lintel may be a collar that is earlier and re-used from another structure; it has an inscription in Welsh. The gable includes a vertical strut and a finial, with timber boarding flanking the entrance. The west front is weather-boarded and features a wide entrance with a shallow segmental-arched head. The sides of the porch have a single band of open timber panels above a high plinth. Inside, there is a plain rafter roof. Attached to the east entrance is a cast iron gate, which has bands of circles beneath the top rail and lock rail, fleur-de-lis finials, and decorative dog-rails.
