[Image: Unrealized proposal for a “Palace of Water and Light” (1940) designed by Pier Luigi Nervi for the never-held 1942 Universal Exhibition in Rome; view larger. Via Oniropolis. Unrelated but potentially of interest, the “10 Mile Spiral” by ArandaLasch].
Palace of Water and Light
An unconventional sports space if it had been built. Office block below, grass ski slope on the roof perhaps?
Building looks a great deal like one in Los Angeles on the 101 freeway.
I have always wondered what it is.
