Bergamo's walls are part of the transnational 'Venetian Works of Defence' site comprising 6 locations in Italy, Croatia, and Montenegro. They showcase the military genius of the Republic of Venice in the 16th-17th centuries.

The most popular entry points are Porta San Giacomo (near the lower funicular station), Porta Sant'Agostino, Porta San Lorenzo, and Porta Sant'Alessandro. Each gate offers a unique perspective and different views.
