Colonne di San Lorenzo

These sixteen marble Corinthian columns date from the 2nd and 3rd centuries and were moved here from a Roman building in the 4th century to form the portico of the Basilica of San Lorenzo. In the square stands a copy of a statue of Emperor Constantine, who in 313 issued the edict in Milan that legalised Christianity.

Behind, San Lorenzo is one of the city's oldest churches, centrally planned, with the chapel of Sant'Aquilino and its early Christian mosaics. A few steps away, the medieval Porta Ticinese opens the neighbourhood towards the Navigli.
