Fort du Mont Alban was built by order of Emmanuel Philibert, Duke of Savoy, between 1557 and 1560 and is one of the most exemplary French military architectural structures dating back to the 16th century.
The purpose of its construction was to reinforce the defense line considerably debilitate as a result of the siege of Nice (in 1543). But what is striking about Fort du Mont Alban is it has survived, as said, in good condition, despite the fact it was considerably affected in World War II.
At present, Fort du Mont Alban is one of the best lookouts on the French Riviera. This feature is owed to its location on a 220 meters high hilly region from where visitors can see virtually the entire Nice at west and Baie des Anges at east.
Fort du Mont Alban stands out as an excellent daytrip idea for people who vacation in Nice.
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.
