The Freudenberg castle was one of the largest castles in region. The main castle dates from the first half of the 13th century and consists of a keep with a trapezoid floor plan. The curtain wall was 80m long and 60m wide and protected by a round tower in the southwest corner.
The castle was built by the Lords of Wildenberg. Later it was owned by several families and the imperial Austria. Because of a dispute over the legacy of the last Count of Toggenburg Freudenberg was besieged on May 26, 1437 by troops from Zurich. The castle was taken by the besiegers, plundered and set on fire.
Since 1985 the site has been owned by the municipality of Bad Ragaz and can be visited freely.
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.
