- Box Tunnel
A two mile long tunnel, built by Isambard Kingdom Brunel through Box Hill. Next to the eastern entrance of the tunnel you can see the remains of a branch from the main London to Bristol railway line which lead into the hillside into the Corsham Ammunitions Depot and terminated at a half-mile long underground railway station which was used during World War II.
