In the Talking Heads song “(Nothing but) Flowers,” David Byrne wrote:

From the age of the dinosaursCars have run on gasolineWhere, where have they gone?Now, it’s nothing but flowers

And here we stand, on the roof of the former Lingotto FIAT factory in Turin, Italy, where architecture firm Benedetto Camerana covered what was a test track—where since 1923 gasoline-powered FIAT cars zipped around in circles after rising up through five floors of the factory—with flowers. It’s all wonderfully symbolic.

The building is a modernist icon. Critic and historian Reyner Banham described how it inspired everyone:

I visited the test track in 2012 and it was … sad. Much of the building had been renovated by Italian architect Renzo Piano. There was a restaurant in the portion of the building on the roof, but the rest of the roof was just sitting there as a missed opportunity.

Now, La Pista 500 has been commissioned by Stellantis (the new name for FIAT) and curated by Pinacoteca Agnelli.

According to a news release: “The 45,000 specimens of 300 species of local biodiversity sown in the extra-large plant basins around the test track have thrived with very little human help—they have flourished naturally and blended in even more with the track’s tissue.”

It is open to the public, displaying artistic and environmental installations. “What is more, sports enthusiasts will be able to practice yoga and meditation in dedicated areas among the flower and herbal basins or jog on the track meandering through the roof garden,” stated the release.

Among the flowers, there are installations by artists Nina Beier, VALIE EXPORT, Sylvie Fleury, Shilpa Gupta, Louise Lawler, Mark Leckey, and Cally Spooner.

There will still be cars up there, but they won’t run on gasoline. “Mondays are dedicated to automotive fans, who will have the opportunity to test drive the new electric Fiat 500 or just look for the newly hatched ducklings of a family of ducks who have spontaneously nested there.”

The narrower, winding test track looks like it will be a challenge for those electric Fiats. But they can probably be rearranged as required. British journalist Will Jennings visited and tells Treehugger, “It’s all in shallow planters and can simply be picked up and moved away if Fiat decides to give it back to another use. That said, it’s exciting to be up there.”

It is all so wonderfully symbolic. A hundred years ago, futurism inspired the design by architect and engineer Giacomo Mattè-Trucco. It was the largest factory in the world, and Italians were entranced by cars and the machine age. Filippo Tommaso Marinetti wrote in the Futurist Manifesto in 1909:

A young architect, Edoardo Persico, is quoted by Banham describing the track as the key feature of the building, noting the entire structure was designed, architecturally and philosophically, to worship speed and the car:

And now …

… it’s all covered with flowers, with a few quiet electric Fiat 500s weaving their way between the planters. What a glorious green transformation—both architectural and philosophical.
