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 eight towns in south-eastern Sicily, including Ragusa, were all rebuilt after 1693 on or beside towns existing at the time of the earthquake which took place in that year. They represent a considerable collective undertaking, successfully carried out at a high level of architectural and artistic achievement. Keeping within the late Baroque style of the day, they also depict distinctive innovations in town planning and urban building. Together with seven other cities in the Val di Noto, it is part of a UNESCO World Heritage Site.
In 1693 Ragusa was devastated by a huge earthquake, which killed some 5,000 inhabitants. Following this catastrophe the city was largely rebuilt, and many Baroque buildings from this time remain in the city. Most of the population moved to a new settlement in the former district of Patro, calling this new municipality 'Ragusa Superiore' (Upper Ragusa) and the ancient city 'Ragusa Inferiore' (Lower Ragusa). The two cities remained separated until 1926, when they were fused together to become a provincial capital in 1927.
