Church of the Assumption and St Mary

The Church of the Assumption and St Mary is an Anglican parish church located in Longbridge Deverill, which is now redundant. It was rebuilt in 1843 by Chapman and Sons. The church is constructed of dressed limestone with a Welsh slate roof and features an ashlar bellcote. The layout includes a nave, chancel, west entrance, and bellcote, designed in a pre-archaeological Gothic style.

The west end has a pointed chamfered doorway with a planked door and a hoodmould, above which is a lancet window also with a hoodmould. The exterior is supported by diagonal buttresses and has a coped verge. The gabled bellcote has one pointed opening. On the south side of the nave, there are three chamfered pointed windows with hoodmoulds, while the chancel features two similar windows and buttresses with offsets. The east end has diagonal buttresses and a pointed window with Y-tracery and hoodmoulds. The north side mirrors the south with similar windows, all of which are diamond-leaded. The building has dentilled eaves cornices, coped verges with kneelers, and cross finials.

Inside, the church has a three-bay nave and a two-bay chancel, with a plain chamfered pointed chancel arch. There is a vestibule and stairs leading to a gallery at the west end. The walls are plain plastered, and the roof features tie-beam trusses. Since the church was made redundant in the 1980s, all fittings have been removed, including a 16th-century chest tomb that is now located in the Bath chapel at the Church of St Peter and St Paul. Some wall tablets were retained during a survey in June 1985, including an oval tablet with carved drapery and crest for Rachel Coker, who died in 1699, a classical marble tablet with an urn for William Morse, who died in 1793, and a Gothic-style tablet for Mary Clifford, who also died in 1793. The church was acquired for conversion into a dwelling in June 1985.
