Watch Terra Senzo Tempo (1969) : Full Movie Online Free This is the journal of an expedition that, starting from the oasis town of Djanet, embarked on a 12-day journey guided by a member of the Algerian Tourism Club to discover the rock paintings of Tassili n'Ajjer in southeastern Algeria. These paintings date back to prehistoric times (10,000 to 5,000 years ago) and are located on an uninhabited rocky plateau whose highest point reaches 2,158 meters. Considered one of the largest and oldest "open-air rock art museums" in the world, the Tassili n'Ajjer boasts a particularly rugged landscape: the vast rocky plains, which sometimes give way to "forests" of monoliths, are riddled with akbas (holes in the escarpments accessible only on foot or by camel) and numerous faults and canyons. The Tassili n’Ajjer National Park was inscribed on the UNESCO World Heritage List in 1982 and classified as a biosphere reserve in 1986.
