Lazise is surrounded by a wall with three entrance gates: from the north Porta Cansignorio, from the east Porta San Zeno, and from the south Porta Lion.
The Cansignorio gate to the north, built with the last stretch of the city wall, after the death of Cansignorio della Scala had military purposes, needing to serve for evacuation in case of necessity. It remained bricked up for the protection of the inhabitants against passing soldiers from 1701 to 1955.
