Barracks at Fort Williamsburg

Roughly horseshoe shape 2-storey barracks block built of local rubble, largely roughcast to the outer side and with a slate roof; red brick chimney stacks with toothed cornices as on the Armoury. Gabled entrance front with immensely tall round-headed arched entry to deeply recessed and much lower door. There is a gabled bellcote at the apex with bell in situ, cast by Mears of London Founders. To the right are two horned 9-pane sashes and to left two slit windows with lozenge-paned glazing. The main accommodation ranges are splayed back to either side around a small courtyard. On the outer side to the right of the entrance is a similar lozenge-paned window and then beyond a corner an elevation with central gabled chimney breast flanked by an assortment of windows and a doorway with bracketed cornice, boarded door and 4-pane overlight; sash windows to 1st floor, that to the right small-pane, and to the ground floor a similar 2-light casement to those on the back of the Armoury. Similar elevation to left of the main entrance except not roughcast.

The main door with slate dressed reveals opens onto a tunnel-passage with arched entry into the courtyard at the far end. Above this inner arch is a boarded loft door. Here the rubble elevations have red brick jambs and infill of different periods; some of the brick appears later C19. Various small-pane sash windows, mostly 12-pane to 1st floor and 16-pane below although there are tripartite windows either side of the entrance. Bracketed cornice to one doorway and an added lean-to porch. Cast-iron hand pump survives opposite entrance.

The fort is roughly square with redans to the four corners and with surrounding ditches and revetment walls.
