The Chantry

The Chantry is a building dating from the late 16th century to early 17th century, with alterations and extensions made in the 18th century and further extensions in the 1970s. The elevation facing Castle Street features rendered pantiled roofs behind a parapet and a moulded cornice, along with rendered and brick stacks. The main block consists of two storeys and an attic with a coped gable end. It has two glazing bar sash windows in the original southern part, plus two cusped arch-headed windows in the gable. There is one sash window in the 18th-century extension to the south, with two on the ground floor. A two-storey, two-window wing set back features a triplet of double Roman tiles, while further to the south is a 20th-century addition.

The south or garden elevation, which was formerly the main facade, has two storeys and three windows, including glazing bar sashes and a two-light mullion and transom window to the east. There is a 19th-century conservatory on the ground floor to the right, which is accessed through a four-centred arch stone doorway decorated with quatrefoil and dagger motifs in the spandrels, all beneath a hood mould. This doorway may have been reused from Thornbury Castle.

Inside, the roof of the original northern part features collar beam trusses with two rows of curved windbraces. The first floor's north-east room has an ogee moulded beam and is a panelled room with small square panels and open scroll catches on the windows. The 18th-century wing to the south contains fielded panel doors beneath four-centred arch lintels. The ground floor's north-east room is panelled with small square panels, has moulded beams, and features a four-centred arch, moulded stone fireplace with an inlaid oak Jacobean surround and overmantel. The north-west room showcases elaborate double ogee moulded beams and a wall plate.
