One of the most visited squares in the city. It's photographed very often as well, as it boasts a statue dedicated to Mozart. Very touristy, as much as the Getreidegasse is, but still worth visiting. Even if you don't plan to, you might stumble upon this place, as it is considered the centre of the Old Town.
