Description
The Church of St Mary Immaculate is a Catholic church built between 1844 and 1845 by architects Weightman and Hadfield. It is constructed of stone and features a slate roof. The church has a four-bay nave, which includes a later addition of a narthex, a chancel, a north vestry, and a south chapel known as the Orrell chapel (with the ritual west being the actual north).
The nave is adorned with three-light windows that have Geometrical tracery, positioned between weathered buttresses. On the north side, there is a small gabled projection at the west end featuring a two-light window. The narthex has straight-headed windows with two pointed lights and a Tudor-arched entrance on the north side. At the east gable end of the nave, there is a bell cote.
Both the chancel and the chapel have a moulded plinth. The chancel is supported by angle buttresses and has a five-light east window with Curvilinear tracery. Above this window, there is a niche with a nodding-ogee canopy that holds a statue of the Virgin and Child. The chapel also features a three-light window, while the vestry has two gabled bays. The interior of the church has not been inspected.
