In the Delaware Copper Mine, during a period of fourty years in the mid 19th century, about 3,600 tons of copper were removed from five shafts. The mine had 10 levels, the deepest one being 430m deep. The tour visits the first level at a depth of 35m, where the copper ore and other geologic specialties are shown. The underground tour is guided, but it is possible to visit the mine in self guided tours too. The paths are safe and well lit, but visitors get helmets, probably juust to create the right atmosphere.
