The extensive network of ancient caves, intricate tunnels, and quarries beneath the vibrant City of Lights is known as the Paris catacombs.

Stretching over a distance of 200 miles (320 km), these catacombs came into existence in the late 18th century as a solution to the grave public health issues associated with the city's overcrowded cemeteries.

The decision was made to relocate the remains of countless individuals to this subterranean location, which now houses the mortal remains of over 6 million people. While a significant portion of the catacombs remains inaccessible to the general public, unauthorized exploration is strictly prohibited, and those caught engaging in such activities can expect severe penalties.

Referred to as "Cataphiles," these daring individuals venture into the cave system illegally. They navigate through hidden entrances scattered across the city, venturing deep underground. However, due to the complex and labyrinthine nature of the catacombs, it is alarmingly easy to become disoriented and lost.

In 2017, a harrowing incident unfolded when two teenage boys found themselves trapped and disoriented within the catacombs for a terrifying span of three days. A search and rescue team, aided by specially trained dogs, eventually located and saved them from their ordeal.
