The fortifications of Messina were a series of defensive walls and other fortifications which surrounded the city of Messina, Sicily. The first walls were built during the Middle Ages in around 1200. A system of bastioned fortifications was constructed around the city in the 1530s and 1540s. The fortifications were modified over the years, with the last major addition being the Real Cittadella, which was built in the 1680s.
