An engraved plaque in the catacombs of Paris:

Optima quæque dies miseris mortalibus ævi.
Prima fugit, subeunt morbi, tristisque senectus:
Et labor, et duræ rapit inclementia mortis.
Georg. Virgil.lib III V.66.

The underground quarry Port Mahon is one of the oldest quarries of Paris. Its use dates back to the 15th century. It has been classified historical monuments January 4, 1994.

The plaque in the wall gave its name to the quarry: path of Port Mahon.

In the quarries of the 16th in Paris, in the Palais de Chaillot. These quarries have been called "catacombs Trocadero" because a part was used in the Universal Exhibition of 1900 to show the public the geology of the basement. Height 55 feet 4 inches / 17 Metes 8693 (as printed on the wall)

We call these underground quarries "quarries of Chaillot". The size of these quarries was 12 acres originally, but now it remains only a small network of underground tunnels. At Expo 1900, we used a small portion of the underground galleries to present the work of mining and underground quarries. A prototype of the Channel Tunnel was also conducted.
