Near the Basilica of Saint Ambrose is situated one of the old entrances to the city, the Pusterla di Sant’Ambrogio. This postern was originally erected as a lookout post in the 12th century. As centuries passed and with the creation of another wall during the 16th century, the Pusterla di Sant’Ambrogio was turned into a prison under the Spanish. Subsequently with centuries of natural deterioration and damage it was reconstructed in 1939 with original features. Above its entrance you will notice a tabernacle dating back to the 16th century and features images of three Saints: Ambrose, Gervasius and Protrasius.
