Clapham South: Deep Level Shelter

North Entrance:

Location: On Clapham Common at the junction of Clapham Common South Side, Nightingale Lane and The Avenue SW 4.

Description: A circular concrete 'pillbox' with a semi-circular brick extension fronting onto the road. There is no ventilation shaft on the roof. There is a square brick ventilation shaft standing a few yards behind the 'pillbox'. This entrance appears to be unused other than for emergency access.

South Entrance:

Location: On the west side of Balham Hill opposite Gaskarth Road, SW 12.

Description: A circular concrete 'pillbox' with small brick extensions on opposite sides that housed the original entrance doors. There is a square brick intake ventilation shaft on the roof. In the compound a few yards to the west is a second brick ventilation shaft with double doors. When inspected in 1995 the tunnels were owned by Security Archives but it was impossible to get into the compound this time but the 'Security Archives' name on the side of the 'pillbox' was gone.
