With a sloping green roof that merges with the surrounding terrain, this wedge-shaped museum of archaeology and ethnography appears to have lifted out of the earth. The building’s verdant crown not only doubles as parkland (it’s an ideal spot for picnics in summer and sledding in winter) but also provides superior insulation, cutting down on energy use. Inside the 172,000-square-foot edifice, visitors can descend through three levels of gallery space as if exploring an excavation site.
