Piazza Duomo matters because it is where Syracuse keeps turning the same piece of ground into a new civic stage. A Greek temple rose here around 480 BCE under Gelon, built to mark his victory over Carthage at Himera; in the seventh century, Bishop Zosimo pushed Christianity directly into that pagan shell by walling the Doric columns into a basilica, and after the Arab conquest in 878 it served as a mosque before the Normans took it back in 1086.[5][9]
