Château d'Hyères was one of the largest castles in Provence. The first mention of the castle dates from 1062. In 1524 and in 1536 the royal armies swept over Provence and Hyères castle was also besieged and conquered. It was reorganised by Charles I of Anjou in 1527 and ultimately dismantled by Louis XIII in a gesture of authority following the destructive religious wars. The castle has been labelled Historical Monument for its important architectural remnants. It offers a spectacular view onto the coast and the islands.
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.
