Piazza San Marco, or St Mark's Square, is the principal public square of Venice, where it is known just as la Piazza ("the Square") because all 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 the lagoon in its south-east corner. The two spaces together form the social, religious and political center of Venice and are commonly considered together.
One of the most beautiful squares in the world, a real marble salon, the city center for centuries, this magnificent square overlooking the water is a mixture of spaces, volumes, and styles: the Procurator's residence, the bell tower, the Doge's Palace. Hugh Honour (British art historian) describes the Piazza San Marco as "beautiful at all times of day or night and all seasons of the year. It is one of the few delicate works of architecture that can absorb a bustling vulgar crowd without loss of dignity; a great city square which retains a feeling of animation when there are few people in it."
