I'm walking in Venice right now....
The Venetian Ghetto was the area of Venice in which Jews were compelled to live under the Venetian Republic.
Today, the Ghetto is still a center of Jewish life in the city. The Jewish Community of Venice,that counts 500 people, is of such cultural vitality that it is often a centre for the cultural life of the entire city.
