École Nationale Supérieure d'Arts et Métiers, Engineering school building near Boulevard Louis XIV, Lille, France.

The École nationale supérieure des arts et métiers de Lille occupies a 26,000 m² site on Boulevard Louis XIV, built in stone and brick in the manner of the great Roubaix manufactories. Its main building, 120 m long and 80 m wide, encloses several courtyards, including the cour d'honneur and a central court holding the grand amphitheatre. The monumental facade carries a pediment sculpted by Alphonse-Amédée Cordonnier.

The school was designed by Jules Batigny in 1885 and opened in 1900 to train engineers and skilled craftspeople. It received protected monument status in 1997 as a valued part of France's industrial heritage.

The school's nickname, "les Gadzarts", comes from the founding at Liancourt, where pupils were called "gars des arts". Inside, a gallery of ancestors lines up busts of the founders, physicists and engineers who built the school's reputation. A Corliss steam engine of the type shown at the 1867 Paris World's Fair, built in 1900, is kept on site.

The campus stands on Boulevard Louis XIV, served by the Lille Grand Palais metro station. The monumental facade and its carved pediment by Alphonse-Amédée Cordonnier face the street, so the building can be viewed from the pavement; the entrance archway and the sculpted female figure on its right are best seen from across the road.

German forces occupied the building during both World Wars, converting it into a military hospital in the First World War. During the Second World War, students were barred from accessing the campus until its liberation in September 1944.
