Modica Castle is located on the top of a small mountain. For a long time it was the political center of the Modica County, inhabited first by the counts and then by the governors, who succeeded each other without ever changing the Castle with other administrative offices. The current structure can be widely visited, although some points have been destroyed over time, still leaving some remains thanks to which it was possible to reconstruct important pages of the history of Modica.
The first construction of the Modica Castle dates back to 8th century, built not only to host the reigning family, but also for military and prison uses. Unfortunately, little remains of the 5 original towers and of the entire walls that surrounded the fortress of Modica, destroyed over time, also due to the earthquake of 1693.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.
