Described by Napoleon as the "Drawing Room of Europe," Venice's principal public square is dominated by Saint Mark's Basilica and the Doge's Palace—as well as its famous pigeons. Wander the framing porticos, have coffee at Quadri or Florian's and just take it all in. Even on the most crowded days, there's a feeling of calm in the eddying whirls of people who gather in this impressive space.
Italy has some very strict rules, one of them being that you are not allowed to feed the pigeons in St. Marks Square. That being said, there are vendors who will happily sell you bird feed! The dance between feeder and feedee goes on all day and it's fascinating to watch. These kids didn't know each other, but they were happy to spend some time together risking poop and histoplasmosis. Consult you physician before approaching the local wild life.
