St Peter's Church, Mansergh

St Peter's is constructed in dressed slate with ashlar dressings and slate roofs. The porch is in timber on a stone base.[2] The architectural style is late Perpendicular.[5] The plan of the church consists of a three bay nave with a south porch, a two-bay chancel with a north transept and vestry, and a west tower. The tower has diagonal buttresses, a south stair turret, and a saddleback roof with embattled parapets on the north and south sides. It has a three-light west window, under which is a plaque recording the rebuilding of the church, and incorporating a panel with the date 1726. There is a doorway on the north side of the tower. The windows in the sides of the nave and the chancel are straight-headed; those in the nave have two or three lights, those in the chancel have one or two lights. The east window and the window in the vestry both have four lights; the vestry also has a doorway. The transept consists of two gabled bays, and contains two-light windows.[2]

Inside the church are waggon roofs. The font is octagonal, and the pulpit is in timber on a stone base. In the tower is an elaborate Gothic wall memorial to a couple who died in 1845 and 1851 respectively.[2] The stained glass in the west window, dated 1865, is by Lavers, Barraud and Westlake. In a north window is glass by Hardman dated 1878.[5]
