Amazon Spheres - limited-access indoor conservatory

The Amazon Spheres are three glass-domed conservatory workspaces completed in 2018 on Amazon's downtown campus, housing a curated collection of thousands of plant species and indoor gardens. The interior is primarily reserved for Amazon employees; public access is available only through limited, scheduled tours or reserved visitor passes, making entry harder to obtain than typical public attractions. The Spheres are frequently cited in coverage of Seattle architecture and corporate campus design.
