Lychgate and churchyard walls at the Church of St Marcella

The lychgate and churchyard walls at the Church of St Marcella are notable features from the Perpendicular style. The large lychgate has a pegged oak superstructure topped with a shingle roof, resting on a chamfered base made of tooled limestone ashlar. It consists of two joined spere trusses with open framing and curved bracing on the sides. The single-bay plan features wide depressed arches on the north and south faces, which are hollow chamfered and adorned with finely-carved Tudor rose and foliate bosses, as well as blind tracery and foliate carving in the spandrels. The tie beams are decorated with crenellated brattishing and feature relief-carved inscriptions in Gothic lettering, with Welsh on the north side and English on the south. The gables are open-framed and braced, showcasing deep verges with moulded and cusped bargeboards. The southern half-gates are made of moulded oak with carved post heads and curved top rails, complemented by simple decorative ironwork. There is also a similar single gate to the left.

The churchyard walls, made of local limestone rubble, rise between 1.5 meters and 2 meters high. The eastern section stretches about 30 meters before curving northward, continuing as a revetment for a similar distance. This area includes a break with a flight of six modern concrete steps that provide access to the raised churchyard. Beyond this, the wall continues north as a low rubble revetment. The main wall features irregular cock and hen copings, while the northern stretch beyond the steps has a mix of cock and hen and slab copings, all of which are heavily overgrown. To the west of the lychgate, the wall is constructed of random-coursed, rough-dressed rubble, with the first few meters featuring triangular copings that curve convexly to end in a flat, shallow buttress. Beyond this, the wall transitions to a conventional style with neat cock and hen copings, extending about 100 meters parallel to the road before turning at a right angle beyond an opening with plain square piers, continuing north to define the western perimeter of the churchyard.
