Description
St Mary Church is a Grade II listed building constructed from coursed brown stone with slate roofs, showcasing an eclectic Gothic style. The church features a nave that is the same height as the chancel, along with aisles, a northwest corner tower, a north transept that includes an organ chamber, and a north porch. The tower is topped with an octagonal stone spire that has lucarnes, and it includes two-light Decorated style windows at the bell stage, stepped buttresses, and a clock. To the left of the tower, there are four bays with paired Caernarfon arched windows in the clerestorey and broad single-light cusped windows in the aisle. The porch has modern doors, while the transept features an oculus in the gable and a three-light window on the ground floor to the north and east, along with three lancets at the east end. The south elevation mirrors the north but does not have a transept; instead, it has a lower chapel at the east end of the aisle and a tall lancet. The west end is adorned with three lancets topped by a trefoil.
Inside, the church is spacious, with a camberbeam roof in both the nave and chancel, which are at the same height with no structural division. The roof beams in the chancel are heavier, possibly indicating a later addition. Broad arches lead to the aisles, supported by octagonal shafts. There is a gallery at the west end featuring a painted panel of the Royal arms of Queen Victoria. The church also contains monuments dedicated to members of the Muspratt family, who established alkali works in the town. To the south of the chancel is a monument to Julia Muspratt, who died in 1857, created by Spence, and to the north of the chancel are monuments to James and Richard Muspratt, who died in 1886 and 1885, respectively, created by E J Physick.
