The amphitheatre was built near the Porta Ticinese ("Ticino Gate") in the 2nd-3rd centuries AD, when Mediolanum grew as economical and political importance while Rome declined. It remained in use until the city was one of the capitals of the Western Roman Empire (4th or 5th centuries). Later it was abandoned after Christianism imposed the end to arena games, but also as, in the wake of the imperial crisis, animals to be used in the amphitheatre were no longer imported. It became a quarry for construction stones as early as the 4th century AD, when the Basilica of San Lorenzo was built.

I like to revel in the dryest details of the great cathedral. The building is five hundred feet long by one hundred and eighty wide, and the principal steeple is in the neighborhood of four hundred feet high. It has 7,148 marble statues, and will have upwards of three thousand more when it is finished. In addition it has one thousand five hundred bas-reliefs. It has one hundred and thirty-six spires—twenty-one more are to be added. Each spire is surmounted by a statue six and a half feet high.

Porta Sempione ("Simplon Gate") is a city gate of Milan, Italy. The name "Porta Sempione" is used both to refer to the gate proper and to the surrounding district ("quartiere"), a part of the Zone 1 division (the historic city centre), including the major avenue of Corso Sempione.[1] The gate is marked by a landmark triumphal arch called Arco della Pace ("Arch of Peace"), dating back to the 19th century, but its origins can be traced back to a gate of the Roman walls of Milan.
