Bamburgh Castle, 23 High Street, Dunbar

Bamburgh Castle is a later 17th century L-plan house with two storeys and an attic, located at 23 High Street in Dunbar. The building is constructed from harled sandstone rubble with dressed stone margins and features a pantiled roof, a slate easing course, crowsteps, and beak skewputts. The gable is harled, and there are brick stacks.

The ground floor serves as vaulted cellerage, with the northern part accessed through a pend, while the larger southern part is now divided and entered from the eastern end through another pend.

The west elevation has four bays and is adjacent to a single-storey outbuilding that projects from the northern bay. There is a pend under the second bay with a door above it. A forestair with iron railings is located to the right, featuring decorative iron door hinges, a handle, and studs on the timber door. The windows have been altered with random arrangements, although some 12-pane glazing remains. There are modern flat-roofed dormers and earlier piend roofed dormers that break the eaves.

The east elevation includes a gabled wing to the south, which may be a later addition, featuring a door at ground level, two first-floor windows, and a small window in the gable head. A stairblock with a narrow window is situated in the re-entrant angle under a swept roof. There is also a later, lower lean-to block adjoining to the east. A pend connects the main block, with windows above and to the right at first-floor level.

Inside, the building has been modernised, but some panelled shutters remain. There is a modelled plaster frieze at the head of the forestair passage, and an early to mid-19th century cast-iron water-spout is affixed to the west facade by the pend.
