Cure d'air Trianon, Art Nouveau building in Malzéville, France.

Cure d'air Trianon is an Art Nouveau building in Malzéville featuring a distinctive steel frame made of four trusses on brackets connected by eight I-shaped beams, all resting on masonry foundations. The foundation walls conceal kitchens and service spaces that supported the establishment's operations.

Built in 1902 on Rue Pasteur in Malzéville for Royer, owner of the Grand Café du Point Central, the guinguette was designed by architect Georges Biet and engineered by Frédéric Schertzer, who ran a metallurgy firm. Its riveted steel frame came from the Pompey steelworks. Open from May to September, it operated only until about 1907, and in 1909 the site was bought by contractor Auguste Bichaton for his summer residence. It was classified as a historic monument on 12 June 1989 for its metal architecture and stained glass.

The ground floor windows display Art Nouveau stained glass featuring historical brand logos like Grande Fine Champagne and Absinthe Cusenier, reflecting the tastes of visitors from that era.

The building sits at an elevated position in Malzéville, offering views over the surroundings with Place Stanislas roughly 2 kilometers away. Accessibility may vary depending on seasonal conditions and current preservation work, so checking ahead is advisable.

The terrace dance floor was covered by a vélum, a canvas awning, while the brasserie occupied the ground floor beneath. The two functions were kept clearly separate in the single-storey steel structure. The establishment operated only from about 1902 to 1907, opening from May to September.
