Clemency Castle is small residential manor adjacent to the church was built in the 1660s in the Renaissance style. It had fallen into disrepair but was fully renovated in 2009 and is occasionally open to the public.
The castle was built in 1665 by Johann Ferdinand von Blanchard, a sire of Clemency. For building materials, he used the ruins of an earlier castle which stood on a site some 30 metres away from today's castle. Fifty years later, it was transformed into the Baroque style of the times. In 1721, after von Lanser had bought the property, it once again underwent transformations. In 1982, Jean Weis acquired the property which was inhabited until 2004.
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.
