Entenstein Castle is a medieval castle surrounded by a moat situated in the center of the town of Schliengen. The origins of the castle can not be clearly dated. The first use of a building at this location can be traced to Walter of Schliengen in 821. By 1000 a tower house might have been in use. In the 13th century, Rudolf von Üsenberg (1207-1231) was the owner of the castle. The name of the castle derives from the German words 'Ente' and 'Stein', which means duck and stone. By 1525, Entenstein belonged to the nobles of Nagel von der Alten Schönstein and was thus transformed to a more representative manor house.
In 1725 Johann Conrad of Reinach-Hirtzbach, then Prince Bishop of Basel, bought Entenstein castle and used it as the seat of the Upper Bailiwick of Schliengen. In 1805, Entenstein Castle became a district site of the Grand Duchy of Baden. After 1857 Entenstein Castle which was then in the possession of the counts of Andlau, an old German noble house, was reconstructed. In 1970 Entenstein Castle was purchased by the Community of Schliengen and renovated thereafter. Since 1975 it funcitions as city hall of the community of Schliengen.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.
