Septfontaines Castle is one of the castles belonging to the Valley of the Seven Castles. It is not clear when the first castle was built in Septfontaines. In 1192, there is a reference to someone by the name of Tider who was Lord of Septfontaines. In 1233, Jean de Septfontaines placed the property under the protection of Countess Ermesinde of Luxembourg. At the beginning of the 14th century, Thomas de Septfontaines, a friend and companion of Emperor Henry VII, was the lord of the castle. In 1600, Christoph von Criechingen built a huge Renaissance tower at the northern entrance. In 1779, a fire destroyed the castle which increasingly fell into ruin. In 1919, the castle was partly demolished but in 1920 the owners attempted to carry out restoration work but unfortunately did not pay much attention to historical architectural requirements. Today the castle is privately owned and cannot be visited.
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.
