The mines of La Presta were exploited from 1711 to extract asphalt, initially for the medical sector. It was not until 1812 that the industrial exploitation, with more than 100 km of galleries, allowed the ore to be exported for the construction of roads all over the world. The mines closed in 1986. The deposit was the largest in Europe. The visit shows how the water was evacuated from the depths and the asphalt brought to the surface by horses, replaced in the 20th century by electric locomotives.
