The city of Rome is full of undergrounds. On the celian hill, under the Temple built for the Emperor Claudius in the 1st century A.D. we find some huge galleries, which were used for the extraction of tuff for constructions. Our tour will take us inside this underground and secret world.
The quarry, explored and studied by the Association Roma Sotterranea between 2004 and 2006, were used for many centuries, probably between the 4th and the 19th century. Inside the galleries, we can observe 16 ancient shafts, the foundations of the medieval monastery, and expecially 3 beautiful underground lakes: the analysis of the water, etraordinarily clean, revealed that the water is pure and potable!
An incredible and unexpected experience in the heart of the city!
