The Museum's subsoil has conserved some 3,400m2 of ruins belonging to the Roman city of Baetulo . Not only is the site exceptional in terms of scale, but for the spectacular nature of certain elements and its innovative display. Visitors can view the site's termae and trace an itinerary through Baetulo's main streets, a stone's throw from the Forum. While the site depicts the city and its inhabitants' every-day life at the height of its splendour, during the rule of Emperor Augustus (27 BC-14 AD), it also contains several posterior constructions.
