New Art Nouveau Museum to Open in Paris to Celebrate Hector Guimard

Paris has finally decided to shine a spotlight on a man most of us know without realizing it. Hector Guimard is the designer behind those iconic Art Nouveau Métro entrances, the ones with curling ironwork and glass that seem to grow from the ground like giant plants. They first appeared in the early 1900s, and though today they’re photographed endlessly by tourists and fill design books around the world, at the time they raised more than a few eyebrows.

Guimard’s creations were nicknamed dragonflies for their wings of iron and glass, and his signature lily-of-the-valley lamps lit the way into the underground. Even the famous green “Métropolitain” sign came from his hand. But instead of immediate praise, the designs shocked Parisians. The green was called un-French, the lettering too strange, and some even said the signs would confuse children and overwhelm foreign visitors.

More than a century later, the very details that critics mocked have become part of Paris itself. And now, with a new museum dedicated to his work, Guimard is finally getting the recognition he deserves.

What is Art Nouveau

Art Nouveau was the design movement that swept through Europe at the turn of the 20th century, and Paris embraced it with flair. It was all about flowing lines, natural forms, and a sense of movement that broke away from rigid classical styles. 

Architects and designers drew inspiration from plants, flowers, and even insects, blending them into buildings, furniture, and everyday objects. The result was a look that felt alive, organic, and a little daring for its time.

Who Was Hector Guimard

Hector Guimard was born in Lyon in 1867 and moved to Paris to study at the École des Arts Décoratifs and later at the École des Beaux-Arts. From early on, he was more interested in breaking away from tradition than following the rules of classical architecture. His influences came from nature and from new ideas coming out of Belgium, particularly the work of Victor Horta, one of the pioneers of Art Nouveau.

By the 1890s, Guimard had started to put these ideas into practice. He designed buildings that seemed to grow like living organisms, with curving facades, fluid lines, and decorative ironwork that blurred the boundary between structure and art. 

Hector Guimard’s Work

His most famous early work was the Castel Béranger, an apartment building in Paris that earned him instant attention and cemented his reputation as a bold new voice in architecture. It also led directly to his commission to design the entrances for the newly built Paris Métro.

When Paris launched its brand-new Métro in 1900, Guimard was given the task of designing the entrances. What he created was unlike anything the city had seen before. Instead of heavy stone or rigid structures, his entrances looked as though they had sprouted from the earth.

Curved iron rails opened like stems, glass awnings spread like wings, and delicate lamps bent down like flowers. They were instantly recognizable as Art Nouveau and just as instantly controversial.

Some Parisians loved the fresh, modern style, but many thought it was too strange, even ugly. The green paint was described as foreign, the lettering was called hard to read, and critics said the whole thing clashed with the elegance of Paris. Yet despite the complaints, Guimard’s designs became the face of the Métro.

Leaving Paris for America

Guimard’s story took a dramatic turn during the Second World War. By then, his style had fallen out of fashion, and new architectural movements had pushed Art Nouveau aside. When the Nazis occupied Paris, his personal life also put him at risk. His wife, Adeline Oppenheim, was an American painter of Jewish heritage, and together they chose to leave France rather than face the dangers of staying. 

By the time Guimard died in New York in 1942 at the age of 75, his reputation had faded, and many of his creations had already been dismantled or discarded. His wife, Adeline, returned to Paris a few years later, determined to keep his legacy alive. She was an accomplished artist in her own right and had exhibited at the Beaux-Arts salon back in 1899, but much of her energy after the war went into making sure her husband’s work was not forgotten.

She donated drawings, furniture, and decorative pieces to museums, particularly in the United States, hoping to preserve what she could. She even tried to gift their Art Nouveau home, the Hôtel Guimard, with its contents intact, first to the French state and then to the city of Paris. Neither was accepted, and the house was eventually carved up into apartments while its furnishings were scattered.

The post-war embrace of modernism meant Guimard’s style was often dismissed as outdated. Entire buildings were demolished, and many of his Métro entrances disappeared. Out of the 167 he originally designed, fewer than 90 survive today. Yet those that remain are now celebrated, even painted by Salvador Dalí in 1970 as part of a work called Tribute to Guimard.

The New Hector Guimard Museum at Hôtel Mezzara

The long wait for a dedicated Guimard museum is finally coming to an end, and the setting couldn’t be more fitting. The Hôtel Mezzara, a townhouse he designed in 1910 for his friend Paul Mezzara, a wealthy textile and lace manufacturer, will become the permanent home of his legacy. 

Tucked away on Rue Jean de la Fontaine in the 16th arrondissement, the building itself is a masterpiece. From its ornate iron gates to the sweeping staircase and stained-glass windows inside, it shows Guimard’s style at its boldest and most refined. Even the kitchen still has original furniture designed by his hand.

For decades, the Hôtel Mezzara had a far less glamorous role, housing students before falling into disuse. Access was almost impossible, which made it one of those elusive Paris buildings people longed to see but rarely could. Now a €6 million restoration project is underway, with plans to open the museum by the end of 2027.

When the doors finally open, visitors will find much more than a beautiful building. The museum will showcase Guimard’s furniture, decorative pieces, and architectural models, along with an archive of drawings and documents that chart his career. 

It will be the first time his work is gathered together in one place in Paris, and the Hôtel Mezzara will give it exactly the stage it deserves.

Where To See Hector Guimard’s Work in Paris

If you want to see Guimard’s work beyond the Métro, head for the 16th arrondissement. Rue Agar is a little side street not far from the Castel Béranger, and it’s like stepping into his mind. Almost every detail carries his signature touch, from the balconies and drainpipes to the street signs. 

Even the smallest fixtures were designed to fit the flowing Art Nouveau style he believed should extend into every corner of daily life. At the bottom of one building, you’ll even find Cravan, a bar that has kept the spirit of the period alive in its design.

Guimard also left behind a series of distinctive houses in Paris. The Hôtel Guimard on Avenue Mozart was both his home and his studio. The original fittings were dispersed to museums after his death, but the exterior still tells you plenty about his vision. 

Hôtel Jassedé, on Rue Chardon Lagache, is another early work and one of the rare survivors from his residential projects. His designs also pop up in unexpected places. You can spot his style in a gravestone at Père Lachaise cemetery, and in a synagogue tucked into the Marais. 

Museums like the Petit Palais, the Musée d’Orsay, and the Musée des Arts Décoratifs also hold furniture and smaller pieces that reveal how far his creativity stretched. Guimard believed design should be total, and Paris still carries fragments of that belief in corners you might not expect.
