It's a small museum, with a couple other notable pieces, most noteworthy being Michelangelo's unfinished prisoners or slave sculptures. Otherwise, not much to see besides the David.
Intermingled with the Renaissance art were a number of loathsome pieces of contemporary art. Most obnoxious was a version of Michelangelo's Sistine Chapel ceiling containing the prominent naked figure of a Mr. Bean type man who had a tremendous "woodie." Kids were disgusted, but couldn't help staring at it. Kinda ruined the visit for me.
