London’s Mile-Long Kingsway Exchange Tunnels to Receive $268M Renovation

In the 1940s, a mile-long series of tunnels called the Kingsway Exchange Tunnels were constructed underneath Central London. Encompassing an area of 8,000 square miles and stretching 7.6 meters in diameter, these subterranean pathways were designed to protect Londoners during the WWII Blitz. Afterward, the Kingsway Exchange Tunnels continued to serve different secret purposes, including as a base for the Special Operations Executive—an offshoot of MI6, and the inspiration for the “Q Branch” in Ian Fleming’s James Bond novels—and housing the secret “hot line” between Moscow and Washington during the Cold War. Soon, people in London might have a chance to tour this piece of history that has been kept hidden for 70 years.

The London Tunnels is a proposed project that will transform the Kingsway Exchange into a public attraction. This set of secret passageways is going to receive a $268 million renovation led by UK-based architectural firm WilkinsonEyre.

“The proposal will adaptively reuse the tunnels to host a series of experiences exploring their history, nature, science, and the arts,” the official statement says. While the plans of what will be included in the revamped version of the tunnels is not yet set in stone, it is likely that it will include various historical exhibits dedicated to the different functions of the tunnels. Additionally, it is likely that the project will bring back the “deepest licensed bar” in London from the Kingsway Exchange days, which featured fake windows and recreational activities like snooker tables.

The Kingsway Exchange was kept out of the public eye for so long due to the British Government’s Official Secrets Act. After the tunnels were expanded during the Cold War, they operated the first Transatlantic telephone cable, TAT1, which helped serve as the secret telephone exchange between Washington and Moscow. While the telecommunication technology became obsolete during the 1980s, most of this equipment will be retained for education purposes and potential historical exhibits in the tunnels. Paul Baker, Director at WilkinsonEyre says: “These secret spaces present the opportunity to tell extraordinary stories that helped shape the 20th century, alongside awe-inspiring digital immersive experiences.”

A potential opening date for the renovated tunnels is 2027. You can follow The London Tunnels on Instagram for updates.
