The Spheres Belltown (Seattle)
Those curious Spheres that have been slowly swelling in downtown Seattle for the past couple of years have revealed their purpose: biophilic inspiration for Amazon workers in the form of a biodome. As of April 2018, tours of the Spheres, including its 40,000 plants, are available to the public on two Saturdays a month—make your reservations here. Understory, a museum-style exhibit on the ground floor where you can learn about the building without touring it, is open daily.
