The Glass Domes at Amazon's Seattle Campus

Seattle for the day, and the main event was the Spheres — the three interlocking glass domes at Amazon's headquarters, 2111 7th Avenue along Lenora. They only opened this year, so the whole block still feels half-finished; a construction crane hung over the skyline in almost every direction we looked.

Up close the domes stop looking like bubbles and turn into an endless lattice of triangles, with tree ferns planted right up against the base. A path curves between the spheres and the towers next door, ferns on both sides, white canopy tents set up on the lawn below for something we never identified.

Inside is the part worth the trip: more than 40,000 plants, including a 60-foot living wall that runs up past the walkways. Misters kicked on while we stood under it, and the fog drifted sideways across the leaves toward the glass.
