The Walls of Bergamo, Province of Bergamo, Lombardy, Italy
From the walls there is a wonderful view of the "Città Bassa", the wide plains as far as the airport of Orio al Serio, and all around the walls a colourful patchwork of cultivated fields, gardens and orchards.

The mighty walls, designed to resist artillery and bombings, were never used in war. In the 19th century on top of the walls a walking itinerary was implemented, and they became and still are a place where the population enjoy to relax in the evenings.
