The Corderie Royale International de la mer is a vast museum complex located in the heart of the maritime Arsenal de Rochefort. The Corderie Royal is one of the most important buildings in the arsenal and was one of the first built when the city was founded in 1666.
For nearly two hundred years, the building, which is more than 374 metres long, was used to furnish the rigging (or cordage) of the French Navy. The length of the central building corresponded to the manufacture of a rope of a single cable length.
In 1926, it was decided to close the Rochefort arsenal, with the consequent gradual abandonment of the Corderie. Today it is home to the International Sea Centre, is a vast museum space that is part of the Arsenal de Rochefort (Grand Arsenal) in Rochefort, France, the city's historic, cultural and tourist landmark, which also includes the Musée National de la Marine (National Naval Museum), the construction site of the replica of the frigate Hermione, and the renovation project of the Office of the Commissioner of the Navy on Rochefort's food wharf.
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.
