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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
