The graveyard at Cimetière du Château, which was founded in 1783, has 2,800 graves, where some of Nice's most famous people lie buried. The cemetery stands on the old citadel of Nice. Even today, some sections of the massive walls of the ancient fortress remain. The fortress, which was built in the 16th century, was once one of the most secure strongholds in France. The cemetery is as much popular for its function and history as for the scenic views of the city that affords.
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.
