St Peter's was built between 1821 and 1824, and was designed by Francis Goodwin. A grant of £13,191 was given towards its construction by the Church Building Commission. The land for the church was given by the patron of the advowson, George 6th Earl of Stamford and Warrington, whose cousin, RevdSir George Booth, had been Rector of Ashton from 1758 until 1797. It was the first of three churches designed by Goodwin for the Commission in the Manchester area. In 1840 a clock was installed with its face at the east end, the mechanism at the west end, and connected by a drive shaft running the length of the church. During the latter part of the 20th century, the west end was divided under the gallery.
Architecture
Exterior
The church is constructed in ashlar stone with a slate roof. Its plan consists of a seven-bay nave with a cantedvestry at the east end acting as a chancel. At the west end is a tower. The tower is in three stages with buttresses at the corners rising to piers surmounted by pinnacles. It has a west door over which is a three-stage window. At a higher level are clock faces under gablets. In the top stage are pairs of open pointed arches acting as bell openings. The parapet is also open and is traceried. Each bay of the nave contains a three-light transomed window. These contain tracery in Perpendicular style constructed in cast iron and painted to look like stone. Between the bays are buttresses rising to pinnacles. The pinnacles at the corners of the church are crocketed. At the east end is a rose window, above which is a clock face in the gable.
Interior
There are galleries on three sides in the church, carried on quatrefoil cast iron columns. The church originally contained box pews but these, and many other furnishings, have since been removed. The stained glass in the east rose window dates from the 1830s, and is by David Evans, of Shrewsbury; it depicts the twelve apostles. On the north side of the church is a window by W. Pointer dating from 1923, and three windows by Curtis, Ward and Hughes from the 1890s and 1901. The south side includes windows by Lavers and Westlake. The three-manual organ was built in 1831 by Samuel Renn, and rebuilt in 1959 by J. J. Binns. There is a ring of eight bells, all cast in 1871 by Mears and Stainbank of the Whitechapel Bell Foundry.
