Katedrala Svetog Marka
On the main square, the splendid 15th-century Gothic-Renaissance cathedral, built by several generations of celebrated local stonemasons, is one of the most important buildings on the island. Enter through the beautifully carved Romanesque main portal, which is guarded by Adam and Eve standing underneath twin lions. Inside the cathedral, there are two paintings by Tintoretto. Be sure to climb the bell tower next door; it's steep and awkward, but worthwhile for the views.
