St John's Wesleyan Methodist Chapel was built in 1866, replacing a temporary building of 1861 in Lloyd Street. The 1866 chapel is built in the Gothic style with a gable-entry plan. The walls are rubble faced with ashlar dressings and it has a sweeping slate gabled roof. Facing Mostyn Street is a gable end with a large decorated west window. This is flanked by a tall three storey tower with pinnacles and an octagonal spire, and by a lower porch. The church is set within its own grounds, now largely a car park. These are enclosed by a dwarf stone wall with ashlar coping and low arrow headed railings. On the north-west side is a vestry range and there is a school room on the south-east side.
