In Casa Grotta del Casalnuovo you can experience a real house of the Sassi through its original furniture and the tools of daily use that the family that lived there used in everyday life. What are commonly called Case Grotta are real ethnographic collections, small museums with objects of common use and work from the times when the Sassi were inhabited, before the depopulation occurred in the fifties. Inside, the original rooms and furnishings of the house are reconstructed before the ancient districts were depopulated in the late 1950s.

The church of Madonna delle Grazie is located in the Via del Sasso Caveoso in Matera. The church was formerly named after St. Eustace, as can be seen from the pastoral visit of Msgr. Saracen in 1543-1544. The entrance consists of a bell tower. It includes a terracotta bas-relief representing the Madonna and Child. The interior of the cave church has only some alterations. Among these is an imposing Baroque altar placed at the original iconostasis. Behind the altar we find a rock wall with several openings that lead to the sacristy; once there was the chancel. In the ceiling there are two carved domes and visible apse arches. On the right wall there is a Crucifixion, now ruined, under which there is a faded fresco.
