Syracuse, Sicily is known as one of the largest and most powerful cities of the ancient world, rivaling Athens in power and splendor. It was the birthplace of the mathematician Archimedes, served as the capital of the Byzantine Empire under Constans II from 663 to 668, and was designated a UNESCO World Heritage Site in 2005 together with the Necropolis of Pantalica.
Syracuse was founded in 733 BC by Corinthian colonists, according to the Thucydidean dating. The leader of the colonists was a man named Archias, and they first settled on the small island of Ortygia, expelling the Sicels who already lived there.
Archimedes was born in Syracuse and led its defense during the Roman siege in 212 BC, reportedly enhancing the Euryalus Castle with traps for the attacking forces. After prolonged resistance, the city fell to the Roman consul Marcus Claudius Marcellus, and a Roman soldier killed Archimedes during the conquest. His presumed tomb is located in the Grotticelli necropolis within the Neapolis Archaeological Park.
