Villa Berthe, Art Nouveau villa in Le Vésinet, France

Villa Berthe is an Art Nouveau residence in Le Vésinet distinguished by rounded openings resembling portholes on its side facades. The structure displays dynamic curves carved into stone and twisted ironwork integrated throughout.

Hector Guimard received the commission from the retired investor M. Noguès in 1896, when he was twenty-nine and also working on the Castel Béranger (1894-1898). The villa reflects his exchange with Victor Horta, whose Hôtel Tassel he had studied, and it was inscribed as a monument historique in 1979, covering its facades, roofs, perron ironwork, interior staircase and decorated ceilings.

The villa's nickname, La Hublotière, comes from the round porthole-shaped openings in the basement of the side facades. Guimard designed the wrought-iron gates, window grilles and entrance ironwork himself, and the interior keeps its original wooden staircase and two decorated ceilings upstairs.

The villa is open to visitors during specific months for guided tours with admission required and limited capacity per visit. Check opening dates in advance and book reservations to ensure access.

The villa's nickname, La Hublotière, comes from the round porthole-shaped openings in the basement of the side facades, which light the cellar. Guimard also designed the wrought-iron gates of the boundary, the windows and the entrance. The rear facade is more asymmetrical than the symmetrical street front.
