Urbs Salvia was a Roman colony founded in the second century BC, and its ruins now form the largest archaeological park in the Marche, forty hectares under the management of the regional archaeological authority.
A theater built in 23 AD on a Hellenistic model still preserves the lower walls of its stage building beneath a three-tiered auditorium, and an amphitheater raised after 81 AD by the general Lucius Flavius Silva, the same commander who took Masada, ranks among the best-preserved examples of its type in the region, its arena measuring fifty-nine by thirty-five meters with semicircular niches that once supported the seating stairs. A temple complex and an on-site museum round out the visit, all open to the public in the quiet countryside around Urbisaglia.
