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
are called "campi". The Piazzetta 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. It is
described here by a perambulation starting from the west front of the church and proceeding to the right. Source
