Unveiling the Hidden Gems: Famous Access Tunnels Around the World

Access tunnels are hidden gems that lie beneath the hustle and bustle of cities around the world. These underground passageways, often unnoticed by many, hold a rich history and offer a unique perspective on urban life. From secret hideouts to transportation networks, access tunnels have served various purposes throughout time. In this article, we will explore some of the most famous access tunnels around the world.
1. The Catacombs of Paris – France:
Deep beneath the streets of Paris lies an intricate network of tunnels known as the Catacombs. Originally limestone quarries, these catacombs were transformed into ossuaries in the late 18th century to alleviate overcrowding in cemeteries. Today, visitors can explore a small portion of these eerie underground passages while marveling at walls lined with bones and skulls.
2. Cu Chi Tunnels – Vietnam:
During the Vietnam War, Viet Cong guerrillas used an extensive network of tunnels in Cu Chi to evade American forces and launch surprise attacks. These tunnels stretched for over 120 kilometers (75 miles) and included living quarters, hospitals, kitchens, and weapons caches. Today, visitors can crawl through a restored section of these historic passageways to gain insight into guerrilla warfare tactics.
3. Shanghai Tunnels – United States:
Beneath Portland’s Old Town Chinatown district in Oregon lies a mysterious network of tunnels known as “Shanghai Tunnels.” These underground passages gained notoriety during the late 19th century when unsuspecting individuals were kidnapped through trapdoors and sold as laborers or sailors abroad against their wills. While some dispute their existence or purpose for human trafficking directly linked to China (hence “Shanghai”), there is no doubt that these dark corridors played a role in Portland’s seedy past.
4. Stockholm Metro Art Tunnel – Sweden:
The Stockholm Metro is renowned for its elaborate art installations across its vast network of tunnels and stations. One particularly impressive art tunnel stretches between the Tekniska Högskolan and Stadion stations. Known as the “blue line,” this tunnel features vibrant blue artwork that reflects light in mesmerizing ways, creating an otherworldly experience for commuters.
5. The Thames Tunnel – United Kingdom:
The Thames Tunnel, located beneath London’s River Thames, was the world’s first successfully constructed underwater tunnel. Designed by engineer Marc Isambard Brunel and his son Isambard Kingdom Brunel, it opened to the public in 1843 after facing numerous engineering challenges during construction. Today, visitors can walk through this historic marvel that paved the way for modern subaqueous tunnelling techniques.
6. Moscow Metro-2 – Russia:
Rumored to exist beneath Moscow’s bustling streets is a secret underground metro system known as Metro-2 or D-6. Allegedly built during Stalin’s rule as a secret transportation network for high-ranking officials and military personnel, its existence remains unconfirmed by Russian authorities. However, urban explorers have reported finding access points to these hidden tunnels, fueling the intrigue surrounding this covert infrastructure.
7. RÉSO – Montreal Underground City – Canada:
The RÉSO (Réseau Express Métropolitain) is an extensive underground city connecting various buildings in downtown Montreal through a series of interconnected tunnels and complexes spanning over 32 kilometers (20 miles). This massive pedestrian network shields residents from harsh winter weather while offering shops, restaurants, offices, and even schools below street level.
8. Edinburgh Vaults – Scotland:
Located underneath Edinburgh’s South Bridge are a series of vaults that were originally intended as storage space but later became slums housing taverns, workshops, and illicit activities during the late 18th century. These dark chambers also housed bodies snatched by notorious criminals Burke and Hare who sold them for anatomical dissection at nearby medical schools. Today, the vaults are a popular tourist attraction with guided tours that delve into the city’s murky past.
9. Wieliczka Salt Mine – Poland:
The Wieliczka Salt Mine near Krakow is not only an incredible feat of engineering but also a UNESCO World Heritage Site. This medieval mine, operational until 2007, features an extensive network of tunnels and chambers adorned with intricate salt carvings, sculptures, and even underground chapels. Visitors can explore this subterranean wonderland while learning about its historical significance and the mining techniques employed over centuries.
10. Sydney Underground Tunnels – Australia:
Sydney boasts a labyrinth of tunnels beneath its central business district that were once used as pedestrian walkways to navigate the busy streets above without interference from traffic. However, due to safety concerns and changing urban planning strategies in the mid-20th century, many of these access tunnels were closed off or repurposed for utility services. Some sections still exist today and offer glimpses into Sydney’s past.
Access tunnels provide us with hidden narratives woven into our cities’ fabric.
