Castrojeriz village is considered one of the landmarks of historic interest in the Camino de Santiago. Its rich history may take up consideration as castro Visigoth, or perhaps, also, Roman fort, (they say was founded by Julius Caesar) in whose castle was developed important battles between Christians and Moors.
The first mention of this castle dates from the 9th century during the skirmishes with the Muslim forces. There are three clearly differentiated sections: the Roman part which is today reduced to an almost hidden square tower; the Visigoth part comprising the extension to the castle with different masonry work from in the Roman part; and the medieval part.
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.
