Via Edmondo de Amicis defines the upper boundary of the Navigli area, in Milan. It is 1,5 Km far from Darsena and equally distant from Duomo. During the Medieval Age, this road flanked the walls of Milan and, in two different places connected the entrance gates to the city centre (Porta Ticinese and Pusterla di Sant’Ambrogio).
Pusterla di Sant’Ambrogio, despite being the minor entrance, is the most fascinating to me. Built during the XII century, the Spanish turned it into a prison in the 16th century. Gino Chierici restored the tower in 1939, rebuilding it after few ruins were left.
