San Marco is the centre of Venice and the city’s main tourist magnet. Piazza San Marco, or St. Mark's Square, was “dubbed” by Napoleon as "the finest drawing room in Europe". St Mark's Square is home to Venice's Basilica di San Marco and the Palazzo Ducale.

Be warned though: this is a very touristic area and the narrow streets around the piazza can get extremely crowded. Here is a short video of the wonderful architecture and atmosphere of the piazza:
