The historian Leantro Alberti who visited Matera in 1550 wrote that the Sassi at night had “a good likeness of the clear serene sky embellished with clear and shining stars”. The visit of Sassi in a night scene still has a unique charm. During the visit you will walk along the paths that best represent the birth of Matera, its evolution, and its most suggestive sights: the dim lights of narrow streets which get in between the slopes of the Sasso Caveoso and Civita; the darkness that makes the deep Gravina canyon almost invisible; the dark caves that merge with the shadows of Murgia’s hills; the squares and the sides of the floor illuminated by light.
