st peter's is built of limestone rubble and has a stone slate roof. the masonry has herringbone work. the plan consists of a nave with a south transept, a porch to the north, and a chancel to the east. the north entrance is norman-style ("on quite a grand scale for a small church"); the round arch of the porch has roll moulding. the church doorway's jamb shafts have capitals with volutes. in the hood mould there is a tympanum with a diaper pattern.
