The bastion of Riva del Garda is one of the icons of the town. Built on the Rocchetta mountain it is easily reachable in 15-20 minutes walking along a paved road. The bastion was built at the beginning of the 16th century to protect the town as well as its inhabitants right after the Venetian domination of Riva had come to an end. The building was destroyed in 1703 by the French troops under the command of General Vendôme.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
