The walkway on the crenellated allows you to look at the castle from an exclusive point of view and you can enjoy a wonderful overview of the city, observing the skyline of Milan as you have never seen it. You go up to the highest part of the castle, along the walkways that connect the various towers, and the tour ends in the Guard Room, inside the Torrione dei Carmini, where you can observe the faithful reproductions of the weapons that characterized the soldiers' equipment. A unique experience, not to be missed!
