We will see the historic entrance to the city.

The extraction of minerals* (quartz, feldspar and granite) started in 1960 by the pioneer Mr. Clemente Bortolotti, over the years has created a huge artificial cave. Deactivated in 1995, its walls designed by the explosions for the removal of ores form a very attractive view. There are large galleries that can be visited, where springs and water infiltrations have created a natural pool, and in some places it is up to 4 meters deep with a constant temperature around 10 degrees, making it a natural nursery for carp. . Since then, the Gruta do Anjo is open to visitors. In addition to the unique and stunning look, ecological pedal boat tours are allowed inside.
