Between 1940 and 1941 a network of tunnels was excavated sixty feet below Hargate Forest on the south side of Broadwater Down in Tunbridge Wells, Kent. No documentary evidence relating to these tunnels survives although there is a strong local rumour that the tunnels would have been used as an underground operations room for Lt. General Montgomery (later Field Marshall) in the event of an invasion.
Entrance to the system is by any of three small blockhouses on the surface of the forest. Inside each blockhouse there is a steep flight of steps leading down to the tunnels. These blocks are not open to the public, but you can clearly see where the bars have been removed and people have gained access to the tunnels.
