Confidential tunnels and caves where prehistoric skeletons were revealed.

These are the ancient man-made tunnels from the 1200s where a prehistoric skeleton was discovered.

Chislehurst Caves, a remarkable site with over 22 miles of tunnels, is located on the outskirts of Kent and on the outskirts of London.

The weaving manmade digs are believed to have been excavated between the 1200s and 1800s.

The tunnels are now technically part of London, but they were originally thought to be part of a nearby county.

When the caves first opened to the public in 1900, visitors were told that parts of the system were inhabited between 6,000 and 4,000 years ago.

The first part of the caves are thought to have been built by druids before being developed by the Romans and then the Saxons around 500AD.

According to the archaeology website Ancient Origins, one of the first historical records of Chislehurst Caves is from a 13th-century charter, and they were used for mining lime-burning chalk and flint.

A prehistoric skeleton was also discovered in the ceiling, which is thought to date back to 10,000 BC or even the Ice Age.

The Saxon charter in the ninth century is the earliest date for anyone working or living in the caves.

The area was transformed in 1865, when the Chislehurst and Bickley Park railway station opened on July 1, making it much more accessible to the public.

This resulted in an increase in tourism, and it was speculated that the caves were mined by the Druids, Romans, and Saxons.

According to the report, this led to a number of underground concerts, and dogs were once brought in to help find members of the public who had become disoriented in the cave mazes.

It is believed that the historic caves were used to store munitions at the start of World War I, and they later became a museum.
