He Art Museum, China, by Tadao Ando

A pair of helical staircases sweep around the skylit atrium at the heart of the He Art Museum, which Tadao Ando completed in Guangdong, China, earlier this year.

Externally, the museum resembles a stack of staggered concrete disks, enclosed by a vertically slatted facade that gently filters light into the gallery spaces. Light is also drawn in through a large oculus in the atrium, designed by Ando to mimic the ethereal use of light in churches.
