A stunning modernist architectural work, courtesy of Renzo Piano, houses this 21st-century science museum and cleverly echoes the local landscape. Curatorially, the museum typifies the city's brainy inquisitiveness, with highly interactive exhibitions that explore the Alpine environment, biodiversity and sustainability, society and technology. Highlights are a truly amazing collection of taxidermy, much of it suspended in a multistorey atrium, along with the fabulous Maxi Ooh! experiential kids area for three- to five-year-olds.
