Opened in 1923, Fiat’s Lingotto factory in Turin had a rooftop test track.
Cars were assembled inside the five-story factory, driven up through spiral ramps, and tested on the roof before leaving the building. At the time, it was one of the most unusual industrial buildings in Europe — a factory where the production line ended on a racetrack.
Fiat stopped using Lingotto as a car factory in 1982, but the rooftop track still remains.
