Next to the cave, the museum offers visitors workshops on prehistoric technologies and the permanent exhibition The times of Altamira, with objects from this site, as well as from the sites of El Morín, El Juyo and El Rascaño. Also part of this exhibition is the so-called neo-cave, an artificial replica of the original caves, built in order to preserve them from the damage caused by a massive influx of visitors.
