Housed in Buckminster Fuller’s striking geodesic dome built for the American pavilion at Expo '67, this nature center has its own geothermal energy system and fun interactive displays involving hand-pumps and water spouts. Exhibits focus on urban ecosystems and emerging ecotechnologies; there’s a model house outside built using sustainable design principles. The upstairs gallery about Fuller, and the exterior belvederes, offer spectacular river views.

At research time, major renovations were underway on the building, although the museum will remain open throughout the work.
