Underground construction filled with skulls in Paris

One of the most famous underground structures in the French capital is the Catacombs of Paris. It is considered one of the most impressive underground complexes in the world. The Catacombs of Paris are part of a network of ancient underground structures that exist beneath the ground of Paris and are also known as 'the mines'.

The origin of these tunnels is limestone quarries, exploited since Roman times.

The walls were filled with bones and skulls.

This is the resting place of hundreds of thousands of Parisians through the ages.
