The archaeological remains found near the Águila Castle seem to confirm the presence of a pre-islamic population, maybe from the Roman Age.
Apparently in 914 the inhabitants of the fort looked like emirales troops burned the city of Algeciras ships that supported the revolt on Ibn Umar Hafsun, in any case the construction of the castle had to be early to be this hard hit area by Berber rebellions and Mozarabic.
The castle was restored in 1839 after it was conquered by French army in 1810. It was however badly damaged in the explosion in 1842.
The Águila Castle is the most representative monument in Gaucin, from the fortress you can see stunning views, in a clear day you can even see the North of Africa.
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.
