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 1 to several thousand, generally numbered from one corner of the area to another, but not usually in a readily understandable manner.

The Sestiere di Santa Croce is found in the north east part of the city and via Piazzale Roma connects Venice to the Mainland.
