Unitarian Chapel

The Unitarian Chapel, built in 1720 with possible earlier elements, is located on Frenchay Common in Winterbourne. It underwent alterations in 1815. The chapel is constructed of rubble with brick dressings and features double Roman and concrete tile roofs. It is a single-storey building with two round-headed, brick-dressed sash windows on three sides, a plain coped parapet, and hipped roofs.

Prominently, there is a square four-stage tower on the south elevation, which includes a square-headed door with voussoirs and a keystone beneath a string course. The tower has remains of moulded pilasters, a single oculus above, a blank oculus higher up, segmental-headed openings at the top stage, a cornice, a pavilion roof, a finial, and a weathervane shaped like Halley's Comet.

Inside, the chapel features two Tuscan columns supporting the valley, a gallery on small Tuscan columns, and a corbelled pulpit with an ogee rear panel and urn. On the rear outside wall, there is an altar tomb with an attached urn marking the vault of the Bruce family, with the earliest date being 1804.
