Sestiere (Venice)

A sestiere (plural sestieri) is a subdivision of a number of Italian towns; for the origin and application of the word, and examples of these towns, see sestiere.The best-known town divided into "sestieri" is Venice. The city is divided into the six sestieri of 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.

These districts consist of parishes — initially seventy in 1033, but reduced under Napoleon and now numbering just thirty-eight. These parishes predate the "sestieri", which were created in about 1170.

Other islands of the Venetian Lagoon do not form part of any of the "sestieri", having historically enjoyed a considerable degree of autonomy.

Each "sestiere" has its own house numbering system. Each house has a unique number in the district, from one to several thousand, generally numbered from one corner of the area to another, but not usually in a readily understandable manner.
