Piazza San Marco is definitely the heart of Venice. In fact Napoleon called it "the most beautiful drawing room of Europe", which sums it up nicely.
Most likely you will find it by following the "Piazza San Marco" signs tacked on to the sides of buildings. Maybe, however, you will be like us-try to follow the signs, get lost, give up, then stumbled upon it!
(Venice can be like that at time, just when you are about to give up, it gives you a reprieve.)
Basilica and the Palazzo Ducale which lie inside Piazza San Marcos are two of Venices most historic sites. The Bastilica is beautifully ornate and the aritechure and detail are not to be missed. You will be drawn in by the domes and arches, an impressive sight that oversees the square.
You will see the Campanile as well, the bell tower that replaced the one that collapsed in 1902. It took 10 years to rebuild but now draws thousands of visitors daily. Climb to the top to see an outstanding view of the city. Some say on a clear day you can see the Alps...
Piazza San Marco is also the location which holds the yearly Carnival parade. Hundreds of people wearing bright, decorative masks stream into the piazza for this event. Muscians, acrobats and mimes all turn out to perform in what is turning into one of Italy's largest parties.
There are many cafes in this area as well, where you can sit and drink (expensive) lattes and watch other tourists feed the pigeons that hover in the square.
Chances are if you are in Venice, you will visit Piazza San Marco. Enjoy it while you are there-and don't forget to bring your camera!
