The St. Mark's Museum, this is a wonderful attraction, not crowded but with amazing art treasures. There is indeed a church, but there is also a lovely monastery, a bit like the central stadium for emptying and meditation. The central square is downstairs with the gallery. Some works by Vla Angelico (Fra Angelico) and several of his contemporaries. The cloisters in the abbey are on the second floor, and each has a unique wet mural for the monks to think about. Each is different and well preserved. If you are lucky enough to come in sunny weather, they will give off a fascinating colour. This strange place costs 4 euros for a ticket.
