Schadau Palace is situated in the Schaudaupark, and was built between 1846 and 1854 according to the plans of Pierre-Charles Dusillon in the Gothic Revival style, for the banker Abraham Denis Alfred de Rougemont
Since 1925 the castle has belonged to the city of Thun and contains a restaurant and the Swiss Gastronomy Museum. Between 1972 and 1992 the façade of the castle was renovated by the city's own quarrymen.
The oldest known surviving panorama was completed in 1814 by Marquard Wocher, and is on display at the Schadau Castle, depicting an average morning in the Swiss town of Thun. As of today it's owned by the Gottfried Keller Foundation.
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.
