Quote : During the height of its popularity in the late Victorian Era, the Granville Hotel had its own named destination on London trainlines to Ramsgate. It is thought there was a tunnel from the hotel down to the sands coming out in one of the properties on the seafront but was closed when the Granville Theatre was built.
Fact : In 1947 when they excavated down to build the current theatre, they capped off this Tunnel. The owner of the Granville Hotel was not amused. This Tunnel was used by the Army in WW2 to get to the beach level and back up to the Clifftop Gun Batteries.
It is believed that this Tunnel came out in the Bombed out and demolished area of the Hotel. No evidence has ever been found of it coming out in the gardens (Poldark Court).
