You don’t even have to step inside to see the art of the Denver Art Museum (a.k.a. the DAM): its ultramodern, extra-angular two-building exterior is a masterwork in itself, designed by world-famous architects Gio Ponti and Daniel Libeskind, respectively.

But once you do, you’ll discover a collection that’s remarkable for a mid-sized metropolis. While it runs the standard gamut from European painting to pre-Columbian artifacts, it’s especially strong in some unexpected areas, namely American Indian art and American graphic design.

But the biggest artistic surprise awaits in the bathroom: when you wash your hands, you’ll be treated to a round of “Row, Row, Row Your Boat,” courtesy of Jim Green’s notorious automatic singing sinks.
