Habsburg Castle near the Aare River was the original seat of the House of Habsburg, which became one of the leading imperial and royal dynasties in Europe. At the time of its construction, the location was part of the Duchy of Swabia.
Around 1020–1030 Count Radbot, of the nearby county of Klettgau in the Duchy of Swabia, had the castle erected. It is believed that he named the castle after a hawk (Habicht) seen sitting on its walls. Radbot's grandson, Otto II, was the first to take the Habsburg Castle name as his own, adding 'von Habsburg' to his title and creating the House of Habsburg.
Habsburg Castle's importance diminished after Radbot's seventh generation descendant Rudolph moved the family's power base to Austria in 1276. Habsburg Castle remained property of the House of Habsburg until 1415, when Duke Frederick IV of Austria lost the canton of Aargau to the Swiss Confederacy.
The original coat of arms to fly over Habsburg Castle, a red lion on a golden field, remained part of the Austrian arms up to the end of the imperial period. The modern arms of the municipality of Habsburg, Switzerland, depict Habsburg Castle.
The area around the castle was covered by forests that were only cleared around 1500, nearly half a millennium after Habsburg Castle was first constructed.
Today the large and small towers of the original castle are preserved, attached to a residential building of the 13th century, while large parts of the complex lie in ruins. The extent of its eastern part is recognizable only by foundation walls. The palatial residence hosts a restaurant and a small exhibition.
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.
