Piazza San Marco (St. Mark's Square) - Piazza San Marco is huge, which is a good thing considering how many people and pigeons are there in the daytime. They swear that the birdseed that is sold to the tourists to feed the pigeons has birth control in it, but if that were the case, wouldn't the pigeons all be gone by now? That tall tower in the background is the Campanile which thoughtfully has an elevator to the top so that you don't have to climb 300+ steps to see the view.
