Description
The Catholic Church of Our Lady of Peace, together with its attached presbytery, was constructed in the 20th century. The complex comprises a tall basilica-style church aligned roughly north-south, with the chancel facing south, and an attached campanile-style bell tower; a small single-storey wing housing the sacristy is attached to the front, in turn connected to the presbytery, which serves as the Priest's House.
The building is constructed of brick, rendered and painted, with a grey pantile roof and overhanging eaves. The five-storey bell tower, located at the southwest, features narrow dividing string courses, small staircase lights, and a bell chamber with four round-arched openings, each with a moulded surround and a small wrought iron balcony with brackets. The bell chamber is capped with a conical roof topped with a metal cross. Lancets have deeply splayed sills and moulded surrounds. The church’s clerestory level features five long, narrow lights. On the east side, the bays are separated at a lower level by triangular buttresses; on the west side, a pitched roof aisle is punctuated by roundel windows separated by pilasters. The chancel clerestory level also has roundels, with lancets positioned below, and a large cross sits within the blank gable end. A small, single-storey, five-sided baptistry is attached to the north side, featuring small round-headed lights. Above the baptistry is a large round window with a stepped surround and an iron “PX” motif in the apex. Attached to the south is the single-storey sacristy range, characterised by hipped roofs, round-arched and roundel windows, and a separate round-arched entrance. The attached presbytery is constructed from the same materials and incorporates grey brick stacks. It has a four-window facade of horned sashes with shutters and a central gabled porch. Being set on a hillside, the rear elevation incorporates an additional basement storey.
The church’s interior is striking for its simplicity; it is rendered and mostly white painted, with colour applied to the roof panels. An unusual feature is an arcade and passage that leads into the church from the west. The main body of the church is divided by a tall, plain chancel arch. The nave is lit to the side by plain, tall, round-headed windows and to the rear by a high roundel, with similar roundels high on each side of the chancel. There is no window above the altar, but instead a crucifix is set within a tall blind arch. A metal screen divides off the rear narthex and baptistry, which has small windows. The roof consists of six bays with trusses comprising a tie beam supported by brackets with a centre post; all members and ceiling panels are painted with stencil decoration. Each bay features a pair of low-hanging, painted wrought iron light fittings. The nave floor is wood, while slate paving is found in the sanctuary and baptistry. The sacristy is oak-panelled.
