The island of Ortygia is an ancient district of Siracusa (Syracuse) that was inhabited into the Middle Ages, long after most areas of equal antiquity had been abandoned. It is here, among graceful limestone palaces, castles, churches and houses, that we find many of the city's rare treasures. A few have been rediscovered following centuries passed - literally - in the dark. One is Giudecca, the city's Jewish quarter.
