Just a short walk from the main thoroughfare lies the Jewish Ghetto, a place of immense historical significance created by a decree of the Venetian Republic on March twenty-ninth, 1516. This is actually the origin of the word 'ghetto' itself. It comes from the Venetian term 'geto,' meaning foundry, because the island previously housed metal casting facilities that made cannons for the Venetian fleet. Because the Jewish community was restricted to this small enclave, they had to innovate to house their growing population. Look up, and you will see some of the highest residential buildings in Venice, reaching seven stories high - true skyscrapers by sixteenth-century standards. For 270 years, the ghetto was closed at night by heavy gates, but it became a vibrant center of cultural exchange and commerce. Today, you can visit the five secret synagogues, often hidden on the upper floors of these buildings, which remain a testament to the resilience and enduring heritage of the Jewish community in Venice.
