Klempenow Castle was built during the time of German settlement in Pomerania in the 13th century and formed part of a series of fortifications on the border with Mecklenburg. The original castle consisted of two towers and a three metre thick defensive wall. It has been substantially altered during the centuries.
During the 17th century it acquired more or less the present shape and look. When Pomerania was ruled by Sweden, the castle was given as a fief to Dodo zu Innhausen und Knyphausen by the Swedish king. From 1762, it belonged to the Swedish Crown. It has since housed several different residents; after World War II, it housed refugees expelled from former German lands and at one time as many as fourteen families lived in the castle. After 1990, a renovation of the castle was carried out.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.
