About the project

A mile of secret Second World War tunnels running 30 meters beneath High Holborn, built as Blitz shelters and later home to the Special Operations Executive and a Cold War telephone exchange that inspired Ian Fleming's Q Branch, is being converted by WilkinsonEyre, the practice behind Battersea Power Station, into one of the world's most unusual visitor attractions. Spanning roughly 8,000 square meters, the scheme layers immersive digital exhibition galleries into the raw tunnel architecture, alongside heritage displays, hospitality spaces and what is intended to be the deepest licensed bar in the United Kingdom, with capacity for millions of visitors a year entering via Furnival Street and High Holborn.
