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.
