Büren Castle was built in 1621-24 as the residence of the Bernese Landvogt over the area. It was built on the site of four farm houses. Between 1624 and the 1798 French invasion a total of 77 Landvogts lived in the castle. Some of the bullet scars from the troops that invaded in 1798 are still visible on the castle walls. Today the castle is home to the municipal administration and government offices. In 2003 the 17th century murals and other art were restored to their original appearance.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.
