A tunnel complex in London that at various times was a deep-level air raid shelter then home to spies, sensitive government records and a strategic telephone exchange, but is now disused, has been put up for sale by its owner, telecoms giant BT.

The ‘Kingsway’ tunnel system was built in 1940 and could hold up to 8000 people. Running off two main tubes, each 400m long, the complex is, in total, approximately 1.6km long. The tunnels were mined more than 35m below the heart of London.

BT is taking prospective buyers on visits to the lair. While the facility has had the full range of utility services during its heyday, and past use of some space in less critical times for recreation, such as snooker (see photo), may suggest future possibilities, BT said restrictions will prevent them becoming a hotel, offices or homes.
