Gessi Bolognesi e Calanchi dell'Abbadessa Park is situated on the hills surrounding Bologna, and is characterized by a series of gypsum outcrops from which a very interesting karst system and the charming Calanchi dell'Abbadessa derive. Although they have been damaged by the past mining activities, Gessi Bolognesi represent one of the main naturalistic points of interest of the area, with dolines, closed valleys, and cliffs shaping the landscape and populated by Mediterranean species and species usually living at higher altitudes.
