The picture is taken in sestiere Cannaregio, one of the six Venice's divisions.
From http://en.wikipedia.org/wiki/Venice)
The sestieri are the primary traditional divisions of Venice. The city is divided into the six districts of Cannaregio, San Polo, Dorsoduro (including the Giudecca), Santa Croce, San Marco (including San Giorgio Maggiore), and Castello (including San Pietro di Castello and Sant'Elena). At the front of the Gondolas that work in the city there is a large piece of metal intended as a likeness of the Doge's hat. On this sit six notches pointing forwards and one pointing backwards. Each of these represent one of the Sestieri (the one which points backwards represents Giudecca).
