Old Church of St Peter

The Old Church of St Peter consists of the ruins of a former parish church. It has a single cell plan, with walls reduced in height except at the west end where they remain full height. The structure shows two phases of construction, identifiable by clear breaks in the masonry on the north and south nave walls. The earlier western half is primarily built of red sandstone rubble, while the eastern half is mainly limestone and slatestone rubble. There are signs that the walls were once externally rendered and limewashed. The masonry of the west gable has experienced significant weather erosion.

The west gable features a high chamfered plinth and a pointed-arched central entrance with a returned label. Above this entrance is a two-light bell-loft window with dressed slate jambs and an oak mullion. There is a tall bellcote from the first half of the 19th century made of limestone ashlar, which has a plain bell-opening. The south entrance is a double pointed-arch design, with a square-headed stoup to the right; the low rubble plinth walls of a former timber-framed porch are still visible. The north entrance is similar but has been blocked up with 19th-century brick. To the left of the north entrance is an irregular circular squint, which has been cut through the wall and may date back to the medieval period, possibly relating to a former anchorite's cell.

The later chancel section includes the base of a former window on the south side and the surviving sill of a four-light, hollow-chamfered east tracery window. Several sections of red sandstone Perpendicular tracery lights are located to the east of the chancel and may be associated with this window. The southeast corner features post-medieval slatestone buttressing that is set back.

There are drawbar holes at both the west and south entrances, with the latter having four-centred inner arches. The chancel and sanctuary are raised, and the sanctuary has a depressed-arched sandstone doorway head that is propped against its south wall, with a projecting keystone inscribed "GI IF Wardens 17[3 or 7][ last figure lost]."

The west wall retains large patches of historic lime plaster and limewash. Approximately 1.8 meters above the ground level on the right side of the west entrance, there are fragmentary remains of painted decoration that appear to be medieval.
