The cultural landscape of the Gobustan stone art encompasses three regions of the plateau of rocky boulders rising from the semi-desert of Central Azerbaijan, with an outstanding collection of more than 6,000 engravings that attest to the 40,000-year-old rock art. The site also presents the remains of inhabited caves, settlements and burial places, which reflects the intensive use by the people of the inhabitants of the area during the wet period that followed the last glacial period, from the Upper Paleolithic to the Middle Ages. The 537 hectare site is part of a larger protected Gobustan reservation
