The Priamar Fortress is a fortress occupying the hill with the same name above the port of Savona. The fortress was built in 1542 by the Republic of Genoa on a promontory where in medieval times was the nucleus of Savona, by design of architect Giovanni Maria Olgiati. However, traces of pre-Roman, Roman and Byzantine presences in the site have been excavated in the past centuries, and are now on display in Savona's Archaeological Museum.
In the 17th century the fortress received bastions designed by the Spanish Royal engineer Domenico Sirena, and in the 18th century were added the commissar's, officers' and Sibilla palaces. In order to create space for the new structures, edifices of the medieval Savona, including its cathedral (built in the 9th century over a pagan temple), were demolished.
In 1746, in the course of the War of Austrian Succession, it was stormed by the Piedmontese grenadiers. In 1820, after the annexion of Liguria to Piedmont, it became a prison. During the Risorgimento, Italian patriot Giuseppe Mazzini was jailed in the Priamar Fortress.
The fortress, which could house up to 500 prisoners, remained Italy's main military prison until 1903, when its role was taken by the castle of Gaeta.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.
