The Albert I Room - general prehistory - presents the principal steps in the history of humanity, from Australopithecus to Homo erectus and fossilized Homo sapiens, thanks to a series of copies and original pieces.  In connection with these human remains, the visitor will discover the remains of the fauna, including many animals that either died out or emigrated depending on the state of ice and inter-ice ages, as well as the industries of successive civilizations; Palaeolithic, Neolithic and the Bronze Age.
The Rainier III Room - regional prehistory - displays local collections, including several tombs which are a point of reference for the Upper Palaeolithic and which come from digs carried out on the initiative of Prince Albert I, from 1895 to 1922, at the ‘Rochers Rouges’ (Grimaldi, Italian Liguria), at the Observatory Cave Monaco and those carried out by the Anthropology Museum since 1945.
Through the diversity of animal species due to successive climatic changes, one can see that these caves served as shelters over a long period.
