Brewhouse Yard Museum And Associated Caves

Brewhouse Yard Museum and associated caves is a former group of four houses, now functioning as a museum, dating from around 1675. The building was restored and converted in 1977. It is constructed of red brick with moulded brick dressings and features a gabled and hipped plain tile roof. The structure has four ridge stacks and a single gable stack, all of which have been rebuilt. Notable architectural details include a plinth, first and second floor bands, and coped gables. The windows are primarily glazing bar casements, mostly with two lights, and are topped with brick flat arches and keystones. The building stands two storeys plus attics, with a symmetrical front that has a three-gabled centre and eight windows, flanked by gabled wings. The ground floor exhibits slightly irregular fenestration, featuring two renewed doors. Each gable has three single windows, while the right wing contains two windows and a five-light window in the gable. The left wing has a similar arrangement, with a door to the left and a four-light window in the gable.

Inside, the museum retains exposed span beams and joists in most rooms, along with two original dogleg staircases that have intersecting strings and turned balusters. At the rear of the building, there are associated caves carved into the face of Castle Rock. These caves consist of various irregular chambers with brick reinforcement and infilling, along with a square shaft leading to the surface. The caves are likely contemporary with the houses.
