Laboratoire d'aérodynamisme de Gustave Eiffel

The Laboratoire d'aérodynamisme de Gustave Eiffel stands in Paris's 16th arrondissement as an architectural research laboratory devoted to aerodynamics. Founded by Gustave Eiffel in 1912, it contains a wind tunnel. The setting links Eiffel's engineering work with wind resistance studies and later tests of aircraft, cars, and building models. The wind tunnel gives the facility its most recognisable industrial feature. When founded, it ranked among the world's first laboratories dedicated to aerodynamics.

Eiffel used the facility to study aircraft during the early twentieth century. This work supported aviation development and later extended into automotive testing with Peugeot. By 1915, Peugeot joined its programme to improve racing-car performance. Later research tested models of automobiles and buildings, supplying data for engineers and architects. Modernised facilities continue research with educational partners, including the Institut polytechnique des sciences avancées and the University of Florence.

Its facades and roofs gained protection as historic features in 1984. The wind tunnel and its components followed in 1997, preserving the apparatus at the heart of the site.
