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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
