Michelangelo carved an impressive statue of David out of marble.  It's imposing, awesome, and well worth a stop if you are in Florence, Italy.

I enjoy checking out sculpture gardens - they are often a great place for interesting photographs.  My visit last week to Minneapolis confirmed it - this crazy (and large!) sculpture of a spoon with a cherry on it is awesome!

Cupid's Span is an interesting (and large!) sculpture along the Embarcadero in San Francisco, CA - well worth a visit to this part of a fabulous city!
