Description
St. Petrox Church is a small church dedicated to the 6th-century Saint Pedrog. It likely dates back to the 13th century, though it has undergone significant restoration, particularly in 1854, funded by Lord Cawdor. At that time, the chancel was rebuilt, and a vestry was added. The building is prominently situated at the north side of the B4319 road. The chancel measures approximately 5.5 metres by 3.5 metres, while the nave is roughly 10 by 5 metres. The church includes a vestry and transept to the north, a porch to the south, and a tower to the west.
The church's exterior reveals original masonry in the north wall of the nave and the west wall of the transept, featuring large sandstone courses with a battered base and smaller rubble courses higher up. A blocked low doorway is visible in the north wall of the nave. The tower is constructed of large, irregular limestone courses and has a battered base, a corbelled parapet with deep crenellations, and louvred belfry openings on all sides. A stair turret projects 0.3 metres to the north and west, also crenellated. The porch and chancel gable have exposed rafter verges without a bargeboard. In the 1850s restoration, the entire south side, apart from the tower, was refaced with snecked masonry in red sandstone, which is considered aesthetically unremarkable. The stone used for the porch appears to come from a different source or quarry stratum than that used for the nave refacing. A new bell turret was added above the chancel arch, replacing an earlier one. The roof is covered with slate, with rafter sprockets visible at the eaves.
The interior comprises a nave, an open tower vault that connects fully with the nave, a transept, a porch, and a chancel. The nave, tower, transept, and porch are vaulted. The 19th-century chancel arch is of two orders, decorated with Early English style corbel caps. Windows throughout are of 19th-century lancet form, excepting the east window, which is a three-light, cinquefoiled design with tracery. A single step is present at the chancel arch and at the altar rail. The chancel floor is paved with Minton encaustic tiles bearing the arms of Lord Cawdor. A 19th-century Norman-style font is also present. Memorials include an unusual brass commemorating William Lloyd (1674), featuring a skull and cross-bones, and a Baroque memorial to Lady Jone Mansell (1692). A modern churchyard cross stands on an old base. The church is a building of group value, primarily listed for its medieval tower and well-proportioned interior.
