Those however that stamped with their presence the island were the Venetians, that they made Syros an important commercial centre of Eastern Mediterranean. The fury of however pirates, with the time forced the residents to transport the capital in the hill, there that today dominates the medieval settlement of Ano Syra, with his church Saint George.
