Adolf Fredriks kyrka ("The Church of Adolf Frederick") was built in 1768-1774, replacing a wooden chapel from 1674, which was dedicated to Saint Olof. René Descartes was first buried to the cemetery in 1650 (before his remains were moved to France). Inside the church is a memorial to the memory of Descartes installed by Gustav III. Other famous people buried in the church cemetery include Swedish Prime Minister Olof Palme who was assassinated only a block from the church, as well as Prime Minister Hjalmar Branting.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.
