The rockshelter of Cova Gran is a large semi-vault hollowed out of Cretaceous limestone, located in the Pyrenean foothills. In the excavations carried out at this site to date, archaeological remains from the last 50,000 years have been found. Excavation is developed on the most recent Mousterian levels, conserved in clastic deposits in the outer part of the shelter. These excavations allowed the detection of a succession of short-time occupations, delimited by well-defined unoccupied levels. The occupation levels include fireplaces and stone tools made of flint and quartzite.
