Description

The Tunnel Passage at Fort Williamsburg is a significant structure that has been tunnelled through the defensive mound bordering the parade ground. This stone-walled passage descends from the tower and transitions into a tunnel beneath a brick arched opening. Inside the tunnel, the sides are cement rendered, and the pavement features brick tracks.

The fort itself is roughly square in shape, with redans at each of the four corners, surrounded by ditches and revetment walls.
