Printemps, the famed French department store (though it’s tagline is NOT a department store) will open at One Wall, alongside and above Whole Foods on Broadway, on March 21.

Founded in 1865 by Jules Jaluzot, Printemps is now a group with 20 department stores in France as well as its in the landmark flagship store at Boulevard Haussmannis. The group also has nine Citadium stores and acquired two e-commerce companies: Place des Tendances and Made in Design.

The store will cover 55,000 square feet on two floors designed to look like a Parisian apartment by the French architect Laura Gonzalez, who recently opened a showroom on Franklin. There will be an all-day cafe, Café Jalu, named after the founder, and a fine dining restaurant, Maison Passerelle, helmed by two-time Top Chef finalist and three-time James Beard award winner Gregory Gourdet.

The store’s departments all have names corresponding to rooms in a house — the Playroom, the Sneaker Room, the Salle de Bain — and there are bound to be some dramatic interior design moments, like in the Boudoir, with gold-colored metal cladding and cracked lacquer screens from the Parisian Atelier Maury. There will be pink marble staircases, stained glass windows, frescoes, and of course the landmarked Red Room — an entire room of red and gold mosaic tile left over from the Irving Trust days of One Wall.
