Reinhardstein Castle is located in valley of the Warche, in the village of Ovifat in the municipality of Waimes (Weismes). It was built in 1354 for Wenceslaus of Luxembourg, while still Count, by his vassal Reinhard of Weismes.
In 1550 following the marriage of Anne Naussau to Guillaume of Metternich, Reinhardstein became the property of this important Rhineland family, until the French Revolution. Abandoned, it fell progressively into important ruin.
In the 19th century it was nearly destroyed by quarrying, and since 1969 has been reconstructed.
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.
