Syracuse (/ˈsaɪrəkjuːs, -kjuːz/ SY-rə-kewss, -kewz; Italian: Siracusa [siraˈkuːza] ; Sicilian: Saragusa [saɾaˈuːsa]) is a city and municipality, capital of the free municipal consortium of the same name, located in the autonomous region of Sicily in Southern Italy. As of 2025, with a population of 115,636, it is the fourth most populous city in Sicily, following Palermo, Catania, and Messina.
Situated on the southeastern coast of the island, Syracuse boasts a millennia-long history: counted among the largest metropolises of the classical age, it rivaled Athens in power and splendor, which unsuccessfully attempted to subjugate it. It was the birthplace of the mathematician Archimedes, who led its defense during the Roman siege in 212 BC. Syracuse became the capital of the Byzantine Empire under Constans II. For centuries, it served as the capital of Sicily, until the Muslim invasion of 878, which led to its decline in favor of Palermo. With the Christian reconquest, it became a Norman county within the Kingdom of Sicily.
