A $400 billion treasure lies underground in England.

Few would have guessed that beneath England lies a system of tunnels and bunkers worth hundreds of billions of dollars, both mysterious and fascinating.

Here are some little-known underground locations in England.

Underground tunnels in Edinburgh

The Edinburgh Underground System, located beneath the South Bridge, was discovered in 1788 and stretches for approximately 300 meters. It is associated with the horrific hauntings of the serial killers Burke and Hare, who dismembered their victims for scientific research. In the late 18th century, many sought refuge there, but were later evacuated when conditions became too dangerous.

The cellar was almost forgotten until 1985, when archaeologists discovered the remaining ruins and brought them to the public. It is now a popular destination for those who enjoy exploration and seek a spooky experience.

The postal railway line in London

Until 2003, Royal Mail used an underground railway to deliver letters and parcels. The railway was dubbed the "best-kept secret" of the postal industry, with over 220 people silently working daily to deliver mail underground.

Williamson Tunnel

Known as a labyrinth hidden beneath Liverpool's Edge Hill, historians believe it was built by businessman Joseph Williamson between 1810 and 1840.

According to legend, Williamson truly believed the Earth was on the brink of destruction, so he decided to build a bomb shelter to protect his family and friends. However, the shelter was later abandoned and fell into ruin until it was rediscovered by archaeologists in 1995. Since then, the Williamson Tunnels have been listed as a National Heritage site requiring protection.

Clapham Bunker

In 1944, the Clapham bunker was built to protect 8,000 Londoners from the bombings of war. After the attack ended, it became a refuge for 492 Jamaican migrants.

Clapham remained almost perfectly preserved for decades until 1998, when the National Heritage Board officially listed the Clapham bunker as a World Heritage Site. The London Transport Museum is accelerating the process of opening tours of the site as soon as possible.
