The Château de Fère-en-Tardenois is a ruined castle in the commune of Fère-en-Tardenois in the Aisne département. Construction of the original castle began in 1206. Little of that remains today. It had seven towers on an enormous artificial motte whose slopes were covered in slabs of sandstone and served as a model for numerous other castles. The connétable Anne de Montmorency, companion of Francis I, transformed the castle in around 1528. In 1555, he enlarged it with the addition of the famous Renaissance bridge carrying a covered gallery. These works were carried out by the architect Jean Bullant (who constructed the gallery at the Château de Chenonceaux) and, possibly, the sculptor Jean Goujon, which would explain the quality of the sculptures, the stone and the colours.
Ownership of the castle is shared by the département and a private company. It is open to the public.
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.
