Congregational Church (including attached Sunday School, gatepiers, walls and railings)

The Congregational Church, which includes an attached Sunday School, gatepiers, walls, and railings, is designed in the Gothic Revival style. It is constructed from roughly coursed and squared sandstone rubble with sandstone ashlar dressings and features a slate roof. The building has a T-shaped plan, with the schoolroom located at the rear. The gabled front showcases a central wheel-window and a recessed arched entrance surrounded by buttresses and gables, with simple tracery windows on either side. The elevation facing Pont Adam includes three windows with simple tracery and a basement-level entrance to the cellars. The gabled end of the schoolroom features a 3-light window with cusped heads, while the rear elevation of the schoolroom boasts a 5-light mullioned and transomed window with arched heads.

The ensemble is complemented by gate piers, gates, railings with fleur-de-lys finials, and a wall along Pont Adam.

Inside, the church has a waggon roof supported by timber trusses that rise from corbels set in the wall. There are tall arched openings with original doors flanking the central pulpit.

The furnishings reflect a contemporary scheme with pitch-pine elements. The pews retain doors and enamelled number plates, and the pulpit features carved foliated panels believed to have originated from the parish church of St. Mary's. The organ, made by Wadsworth & Bro. of Manchester, has painted and stencilled pipes, and the church is illuminated by chrome and glass electric lights from around 1930. The schoolroom has an inserted ceiling.
