Matera Sum

Matera Sum is an underground site located in Matera, in Basilicata, which represents a fascinating example of environments carved into the rock.

After a conservative restoration intervention, the site was made accessible to the public, offering the possibility of discovering what was once a real underground city.

Matera Sum is a path over 1000 meters long, located 25 meters below street level, and features houses built in such a way as to allow light and air to penetrate inside through cracks or holes.

Unlike the Palombaro Lungo, this site has never been used for water collection.
