The Château de Wangenbourg is a ruined castle in the commune of Wangenbourg-Engenthal. In 1504, Holy Roman Emperor Maximilien I, having vanquished the Prince-elector, Philipp, in the war of succession of Bavaria, confiscated the castle from the Lords of Wangen, cousins Hans and Stephan von Wangen, for the favor to count Tiestein, who himself gave it to the Archbishop of Strasbourg, Wilhelm III von Hohnstein, in 1516. Nevertheless, a branch of descendants of the von Wangens, Georg and Hartmann, continued to occupy the castle. Between 1535 and 1550, they reconstructed their logis in the Renaissance style.
From 1578, the Archbishop of Strasbourg and the lords of Wangen disputed property rights concerning the castle. The Wangens were expelled in 1578, but re-established their rights in 1595. In 1680, the castle was occupied by French troops. In 1702, it was in ruins.
Restoration of the castle started at the beginning of the 20th century, and again in 1931. The footbridge in the photograph was constructed in 1961 to replace the old drawbridge.
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.
