St. Mark's Square

Piazza San Marco, often known in English as St Mark's Square, is the principal public square of Venice, Italy, where it is generally known just as la Piazza ("the Square"). Almost all the other urban spaces in the city (except the Piazzetta and the Piazzale Roma) are called campi ("fields"). The Piazzetta ("little Piazza/Square") is an extension of the Piazza towards San Marco basin in its southeast corner (see plan). The two spaces together form the social, religious and political centre of Venice and are referred to together.
