The Columns of San Lorenzo are one of the most fascinating relics of Roman antiquity in Milan. Located in front of the basilica of the same name, they represent an important historical and cultural landmark. The colonnade, composed of 16 marble Corinthian columns, dates back to the 2nd or 3rd century AD.

They are thought to have originated from a Roman temple or public building and were moved to their current location in the 4th century. Over the centuries, the Columns have become an integral part of Milan's urban fabric.
