London’s Secret Underground Tunnels to transform into Modern Tourist Attraction

Beneath London’s bustling heart lies a world shrouded in mystery and history. The underground tunnels, a former secret, are now the focus of a monumental transformation spearheaded by London Tunnels Ltd.

With a secretive past, these passages will transform into state-of-the-art museums and attractions, blending history with modern engineering.


Built-in 1940, the Kingsway tunnels were bomb shelters, offering refuge during the Blitz. Their purpose evolved, and it was integral to British Secret Service operations in World War II. From these tunnels, the Special Operation Executive conducted espionage, sabotage, and reconnaissance in occupied Europe.

The tunnels, measuring 8,000m² and 7.6m in diameter, were a state secret for most of the last century. They served as a wartime sanctuary and played a role in the Cold War. Enlarged and fortified, they housed a secure telephone exchange, operating the first Transatlantic telephone cable, TAT-1, the “hotline” between the White House and the Kremlin.
WSP, collaborating with Wilkinson Eyre, Montagu Evans, and Gardiner & Theobald, is conducting engineering surveys and consultancy for the £220M project to transform the tunnels into a modern marvel.

The consortium, led by Angus Murray, London Tunnels Ltd, has invested £140M in restoration, with £80M for interactive features. The project preserves history while introducing contemporary innovations.

Visitors will be immersed in a world where history and technology converge. High-resolution, curved screens will bring the past to life, complemented by interactive structures, scent-emitting technology, and acoustic pinpoint speakers.

The attraction will host experiences in partnership with entertainment businesses, artists, performers, and curators. With a 2M annual visitors capacity, the tunnels will become a nexus where past and present meet.

Challenges include waterproofing, soundproofing, and ensuring structural safety. Every phase balances historical integrity with modern amenities. The tunnels’ history, scale, and location create a unique prospect for an educational and entertaining attraction.

Completing this project will unveil a hidden chapter of London’s history and showcase contemporary engineering ingenuity. Visitors will walk the paths where history was made. The tunnels will invite the world to a unique cultural experience, offering an unparalleled journey through time.
