It’s one of those pieces of cultural knowledge that I could kick myself for not knowing already (there’s a lot: case in point, I hadn’t seen Rebel Without A Cause until a couple months ago), especially since it’s on top of the intersection of three lines of CKB-bait: machine age art movements, architecture, and automobiles.
In 1921 the Fiat company built a new factory in Lingotto, Turin, and to maintain compatibility with the proper Italian-futurist manifestos of the time, a test track was built on the roof…

Raw materials for cars would enter on the first floor with the assembly line continuing upwards in a spiral until the finished Fiats exited on the roof where the test track was. Reminds me of Steve Jobs’ dream factory: a beachfront site that would process the sand into silicon and output fully-formed PCs at the other end.
After reading about the factory in Banham’s Theory And Design In The First Machine Age, I concluded that there was just no way something so awesomely absurd could still exist. Bzzt! The Lingotto factory is still around and was repurposed into a conference and sports center complete with a swank hotel. (Google map link)
