I agree with the reviews praising vaporetto rides and exploring backstreet Venice on foot. At San Zaccaria Church, I saw a beautiful Bellini altarpiece with a joyous angel playing the cello. I also loved seeing Emma Ciardi's Impressionist paintings of Venice at the Ca' Rezzonico 18C Museum that is in a gorgeous palazzo. The Ca' d' Oro is another lovely palazzo with a fascinating collection of paintings and sculptures. Palladio's San Giorrgio Maggiore made me realize why Palladio is often copied in other nations.
I agree with the review that said Venice is the world's most memorable city.
