Florence - Sunset over Arno by Giuseppe Torre :( I miss it SO MUCH. And I must get back here someday so I can get to the top of Il Duomo, and watch the sunset on the Arno from the top of San Michaelangelo.
Michelangelo, Sistine Chapel, Vatican this shows both the ceiling and the last judgment. The ceiling is a beautiful work of art with great detail. The last judgement even has more detail and it was done 29 years after the ceiling.
