San Marco Square is the central gathering place in Venice. Make a point to visit the square during the day and at night. You will be amazed at how different the same place can feel.
At the eastern end of the piazza stands St. Mark’s Basilica, which is a gorgeous cathedral (like all cathedrals in Italy seem to be).
The plaza is always busy, with street entertainers, tourists, and vendors. Just outside of San Marco Square, the small streets that branch off are filled with shops selling everything from Murano glass to Venetian masks. You’ll also find a variety of high end retailers and a lot of restaurants and gelato shops.
