The Roman Bridge at Saint-Thibéry was segmental arch bridge on the Via Domitia in southern France. The structure is dated to the reign of emperor Augustus (30 BC – 14 AD). The ancient bridge had nine arches with spans of 10–12 m. The roadway rested on wide piers, which were protected on both sides by arched floodways and large cutwaters. The original length of the structure is estimated as 150 m, its road width as 4 m. The missing spans are known to have been destroyed by flood some time before 1536.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.
