Housed in a former convent adjacent to a Roman amphitheatre (the remains of which are in the garden), the archaeological museum covers Arezzo's history from the Etruscan period through the Roman era. The main draws are the Etruscan bronzes and the collection of Arretine ware — the elegant red-glazed pottery that Arezzo produced in industrial quantities during the 1st century BC and was traded across the Roman Empire.
The Roman amphitheatre in the adjacent garden held 8,000–10,000 spectators and is largely excavated; you can walk through the ruins. The museum is small enough to see in an hour without rushing, and the combination of the collection and the amphitheatre makes it one of the better stops in the city.
