London’s Hidden Wartime Tunnels Now Set to Open as Exclusive Spy Museum, Memorial, and Underground Bar in 2028 – A Must-Visit Tourist Attraction – Travel And Tour World

As part of a development that is expected to rebrand London’s heritage tourism industry, a hidden network of Second World War tunnels located beneath the British capital city will be rebranded as a museum of espionage, memorial, and underground bar by 2028. Located 100 feet down from busy Holborn streets above, this 90,000 square-foot site that used to serve as an important command center for British Second World War initiatives will entice tourists with its rich history and interactive exhibits.

This newly-approved development, set to draw in millions of tourists annually, will offer an immersive experience that links London’s past wartime efforts with the present day. From its role as a shelter during the Blitz to its influence on James Bond’s creator, this underground labyrinth holds the secrets of the past, making it a must-see for history buffs, spy enthusiasts, and curious travelers alike.

A Glimpse Into London’s Hidden Wartime History

The tunnels date back to 1940, during World War II, when Britain feared invasion from Nazi Germany. Originally designed as bomb shelters capable of housing up to 8,000 people, the tunnels were finished by 1942, just after the Blitz had ended. Despite no longer serving as shelters, these tunnels were quickly repurposed for use as a government communications center and a base for the Special Operations Executive (SOE), the secret unit tasked with conducting espionage missions in Nazi-occupied Europe.

James Bond author Ian Fleming, who worked as a liaison officer to the SOE, is thought to have drawn inspiration from the tunnels when crafting the world of Britain’s most famous secret agent. The underground complex is rumored to have influenced Fleming’s depiction of the MI6 headquarters in the Bond series, with some even referring to the site as “the Q Branch of James Bond,” a nod to the MI6 gadget-maker and inventor of the world-renowned spy gadgets.

“The history here is extraordinary,” says Angus Murray, the CEO of The London Tunnels, describing the site as an amazing location filled with stories of espionage and wartime secrecy. “It’s an amazing space, an amazing city, and I think it tells a wonderful story.”

Plans for the Underground Spy Museum and Memorial

When it opens in 2028, The London Tunnels will house a variety of attractions, beginning with a military intelligence museum showcasing more than 300 years of history related to Britain’s military operations. Moving away from a narrow military focus, the museum will highlight the essential question of how military intelligence has evolved over time: How do you tell truth from lies? This theme will run through exhibitions that explore the tactics and tools used in intelligence gathering throughout the centuries.

The site will also feature a memorial to the more than 40,000 civilians who lost their lives during the Blitz, providing visitors a solemn space to reflect on the impact of the air raids on London during World War II.

“We want people to understand the critical role intelligence played, not just during the war, but in shaping the modern world,” said Alistair, the chair of the museum’s board of trustees. “There’s still so much about the SOE that remains a mystery. Most agents never spoke about their work, and many records have been lost or destroyed.”

In addition to these immersive exhibitions, visitors will be able to visit what is set to become the world’s deepest underground bar. As part of its design, the bar will be an attraction in its own right, drawing in guests with its unique location and history. It promises to be an incredible place to enjoy a drink, surrounded by the mystery and intrigue of wartime history.

The Cold War and Transatlantic Communications

After World War II, the tunnels continued to play an essential role in Britain’s national security. The site was home to a secure telephone exchange and a terminus for the transatlantic undersea telephone cable. During the Cold War, it became the focal point for a secure “red telephone” hotline between the Pentagon and the Kremlin. These communications, which helped defuse the tension of the Cuban Missile Crisis, ran through these very tunnels, underscoring their continued importance as a nerve center during one of the most dangerous periods of modern history.

The Future of the Tunnels: Tourism and Accessibility

After being decommissioned in the 1990s due to the obsolescence of the technology housed there, the tunnels were largely forgotten until 2023 when BT (British Telecom) sold the site to Murray’s private-equity-backed group. The plan for its transformation into an interactive tourist attraction was approved in 2024, and construction is now underway to bring this vision to life.

Once completed, the site is expected to attract up to 4.2 million visitors each year, blending history, heritage, and novelty in a way that will surely become one of London’s most unique tourist destinations.

“We’re not just creating a museum; we’re creating a space where history comes to life,” says Murray. “If you visit and say, ‘I went to this cool underground tunnel today,’ that’s just the beginning. Inside, we’ve got an experience that will leave you in awe.”

A Unique Visitor Experience

Its 2028 launch will be savoured by history buffs, Bond fans and tourists who want a taste of London’s great and hidden history. When its development stage is complete, its own site will publish further news and guest information and ticket sales for tours and events.
