The Nieuwpoort belfry tower (as part of the city Hall) is one of the 56 belfries in Belgium and France, whose has been declared as a UNESCO World Heritage Site.
The belfry stands above the rectangular city hall which originates from the 14th century. During the First World War tower and the hall were, along with the entire city, almost completely destroyed. In 1921-1923 the belfry and the hall were reconstructed. The hall has the same appearance as the first suspected in 1280.
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.
