The historical city is divided into six areas or "sestiere" (while the whole comune (municipality) is divided into 6 boroughs of which one is composed of all 6 sestiere). These are Cannaregio, San Polo, Dorsoduro (including the Giudecca and Isola Sacca Fisola), Santa Croce, San Marco (including San Giorgio Maggiore) and Castello (including San Pietro di Castello and Sant'Elena). Each sestiere was administered by a procurator and his staff. Nowadays each sestiere is a statistic and historical area without any degree of autonomy.
