The Archaeological Museum of Milan is located in the ex-convent of the Monastero Maggiore, alongside the ancient church of San Maurizio al Monastero Maggiore, with entrance on Corso Magenta.
The first part of the museum, sited in the original site of Corso Magenta, is dedicated to the history of Mediolanum founded in the 4th century BC and conquered by the ancient Romans in 222 BC. In the basement floor there is also a small section about Gandhara's arts.
The inner cloister, where Roman remains and two medieval towers are visible, connects the first part of the museum with the new building sited in via Nirone. In this part of the Archaeological Museum of Milan are sited, on four floors, the Early Middle Ages section, the Etruscan section, the Ancient Greek section and the temporary exhibition room.
In the Middle Ages polygonal tower sited in the inner cloister are exposed a Domenico Paladino sculpture donated by the artist to the museum that fits in the frescoed medieval structure.
Collections of the museum from prehistoric and Egyptian civilisations are housed at the Castello Sforzesco Museums.Statues and tombs from ancient Rome are displayed along the cloisters of the former monastery, and a path leads from the cloisters to a "polygonal tower with early medieval frescoes and comes out in the new museum in Via Nirone where the early medieval section is on the first floor."
