The site where Kaggeholm Palace is located was first mentioned in a document in 1287. During the 1500s the farm was owned by members of the families Grip and Bååt. The farm was originally called Vettersjö, but was named by Swedish Count Lars Kagg (1595-1661) who bought the manor during 1647. Kagg was a political ally of King Gustavus Adolphus, a member of the Privy Council of Sweden and Field Marshal during the Thirty Years' War.
The chateau-style mansion was built in 1725 and designed by Nicodemus Tessin the Younger. Since 1939 it has been owned by the Swedish Pentecostal movement and is used as a training center by nearby Kaggeholm College.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.
