Columns of San Lorenzo

The Colonne di San Lorenzo is the best-known Roman ruin in Milan. It is located in front of the Basilica of San Lorenzo. It is a square with a row of columns on either side, which were taken from a temple or public bath house dating from the 2nd century. The columns were moved to their current location sometime in the 4th century. South of the columns, one of the medieval gates of the city is still in place, with Roman marbles in it.
