The earliest record of the Riilahti village is from the 15th century and first manor was established about one hundred years later. From the year 1725 Riilahti has been owned by the noble family Aminoff. The present manor house was built in 1803-1806 by Pehr Granstedt. It’s surrounded by the large English style park.
Sweden and Russia fought massive naval battle near Riilahti in 1714. Today there’s a monument of the battle near the manor. Riilahti provides nowadays conference facilities, horse riding and cottage rents. Guided tours are available for groups.
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.
