Reputed to be the Reserve Central Command HQ. Evidently dug as an alternative position to Dumpy 'A' beneath the Casemates at Dover Castle. The tunnels comprise a main entrance, with a secondary entrance to the east. Map ref for main entrance is TR342426. A re-survey was made on 14/9/81 and the buildings demolished and covered with topsoil. No indications of entrances remain (Dover Tunnels). No traces of the tunnel entrances were found during this survey, though an area of entangled wire and concrete lies against the field edge at TR34164258 (1)
