Trenton Teapot Museum
As the name suggests this museum only has teapots. But don't let that dissuade you from visiting and seeing the unique collection of receptacles. They come from all over Europe and every shape and size imaginable are displayed here. The museum claims to have the largest collection of teapots in the world. Although they have normal operating hours it's best to call ahead to see if they're open on the day you plan to visit.
