Charles Fort

Attached four-bay single-storey dormer attic former ordnance shed, built c.1750, attached to battlement wall to rear (east), now in use as cafe. Single-pitch slate roof with recent rooflights and cast-iron rainwater goods. Rubble stone walls with rubble stone plinth. Square-headed window openings with stone sills to front (west) elevation, having replacement eight-over-eight pane timber sliding sash windows, red brick block-and-start surround to southern window of front elevation. Square-headed door openings to front elevation having replacement double-leaf timber battened doors. Partially covered drain and path to west having limestone flagstones.

This building is distinctive for its high single pitch roof and low façade. While the fort's ramparts and bastions retain much of their original seventeenth century form and fabric intact, buildings were added within throughout the eighteenth and nineteenth centuries to meet changing military requirement. Together with these structures, this building forms part of an outstanding architectural group which has played a significant role in the country's history.
