Do not ask the Venetians where such a square or such a street is located because you would hear the answer that in Venice there is only one square and it is in the San Marco district, that is Piazza San Marco, and only a handful, at most, of streets. These elements are replaced by campi and campielli - for the squares - and by calli - for the streets. Even the Spanish-speaking cousin uses the word calle to indicate the street (
salir a la calle a tomar el aire sounds more or less to us like going out for a breath of fresh air).
The origin of the name campo derives from the memory of the surfaces present in the past, sometimes with cultivations, in clay or lawn, as evidenced by the field in San Pietro di Castello, still admirable today in a luxuriant green. Then there are the campielli so called due to their smaller size, and finally the campazzi due to their larger than normal size.
The name assigned to the fields can originate from various things: families, activities that took place in the same, saints, etc.
The fields have always been a meeting place for the inhabitants of the area as well as a place for entertainment, for disputes and, more recently, for a more common children's play area. In many of them, there are wells that once served as rainwater containers and fountains still functioning to quench the thirst of the citizens. A respectable water network, which gave drink to the whole city and the Venetian islands.
It is useful to keep in mind that Venice, like every other city in the world, has undergone countless urban transformations and even the fields today do not faithfully reflect the city reality of other times. Some, for example, hardly exist anymore, others have been halved in their size, and still others have been revised. Many others, in fact, were in clay or lawn and the territory itself has expanded more over time.
Today, with rare exceptions, the fields are paved with stone.
It should therefore be considered that Venice today has its own large municipal territory, which leaves the area represented by all the sestieri and also includes the islands of the lagoon as well as the Venetian mainland. For this reason the entire municipality of Venice therefore includes more than one square - such as Piazza del Priorato in the Lazzaretto Vecchio, Piazza Galuppi in Burano, Piazza Maggiore in Malamocco, Piazza Ferretto in Mestre, Piazza Mercato in Marghera to name a few, even if the The square par excellence, the one with a capital "p" remains for everyone Piazza San Marco, both for its size and for the historical events that took place on its surface. At the Lido of Venice and in the Venetian mainland, the streets regain possession in indicating the urban toponymy.
And yes, there is also a square, much more recent in the life of Venice: Piazzale Roma, the point of arrival and departure, among others, of urban and extra-urban transport.
