Piazza della Rotonda Piazza della Rotonda The Piazza della Rotonda is a piazza (city square) in Rome, Italy, on the south side of which is located the Pantheon. The square gets its name from the Pantheon's informal title as the church of "Santa Maria Rotonda". Although the Pantheon has stood from antiquity, the area in front of it had over the centuries become choked with a maze of sheds and small shops that had grown up around its columns. These medieval accretions were cleared by order of Pope Eugenius IV (1431–39) and the piazza was laid out and paved. It took its name
Piazza San Marco from the lagoon surging up into the Square. Books Piazza San Marco 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"). 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 (see plan). The two spaces together form the social, religious and political centre of Venice and are commonly considered together.
