Piazza San Marco, is the principal public square of Venice, Italy, where it is generally known just as "the Piazza". All other urban spaces in the city (except the Piazzetta and the Piazzale Roma) are called "campi" (fields). The Piazzetta (the 'little Piazza') is an extension of the Piazza towards the lagoon in its south east corner. The two spaces together form the social, religious and political centre of Venice and are commonly considered together. This article relates to both of them.
A remark usually attributed to Napoleon calls the Piazza San Marco "the drawing room of Europe" (the attribution to Napoleon is unproven). It is one of the few great urban spaces in Europe where human voices prevail over the sounds of motorized traffic.
