Since the 14th century craftmen’s guilds were significant brotherhoods who drove interests of their members. The big guild of Tallinn was an union of wealthy merchants. Their base was the Great Guild Hall in downtown, opposite the church of Holy Spirit. The building itself was built in 1407-1410 and is a well-preserved sample of Medieval construction.
Today the Great Guild Hall houses a museum presenting Estonia's history from prehistoric times right up to the end of the 20th century. Films and interactive displays show how people here lived, fought and survived over the last 11,000 years.

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.
