Gatehouse at Fort Williamsburg

Gatehouse designed more in the manner of a Neo-classical garden pavilion. The main part faces the former parade ground and is of red brick construction, now cement rendered, and with a hipped slate roof and bracketed eaves. This roof is continued back over the lean-to rear entrance of rubble construction. The symmetrical front has a central 2-order arch flanked by smaller blind arched recesses below a deep bandcourse at impost level with paterae ornament; plaster roundels above. The recesses have viewing slits. Arched entrance at the opposite end and attached footbridge over the ditch.

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

Central slate flagged path flanked by cobbled floor with geometric pattern of medallions, hearts and flowers. The later part is a single chamber and there are further viewing apertures through to the rear part that tunnels into the bank.
