Brussels, World Capital of Art Nouveau.
When thinking of Art Nouveau, one immediately thinks of Paris, Vienna, or Barcelona. But few know that Brussels was the true cradle of this artistic movement, which revolutionized architecture, decorative arts, and design between the late 19th and early 20th centuries. It was in Brussels that Victor Horta, the father of Art Nouveau, built his first innovative works, now recognized as a UNESCO World Heritage site.
Walking through the streets of Brussels to discover Art Nouveau means immersing oneself in a world of curved lines, floral motifs, wrought iron, stained glass, and mosaics. It is not just about visiting museums: Art Nouveau is still alive in the neighborhoods, in the facades of residential buildings, in the entrance doors, in the railings, and even in the street lamps. This guide will take you through two thematic routes that touch on the most significant places, allowing you to appreciate the elegance and innovation of this unique style.
Victor Horta: The Architect Who Changed History
Victor Horta (1861-1947) is considered the founder of Art Nouveau in architecture. Trained in Paris and influenced by the theories of Viollet-le-Duc, Horta developed a personal style characterized by the bold use of iron and glass, an open and fluid layout, and decoration integrated into the structure. His houses and palaces rejected the symmetrical patterns of classicism, preferring curved lines that imitated stems and tendrils.
Horta built about ten works in Brussels, many of which are now open to the public as museums or can be visited externally. His houses have influenced architects across Europe, from Hector Guimard in Paris to Antoni Gaudí in Barcelona, although the latter developed a more personal style. For those planning a vacation in Brussels, a dedicated itinerary to Horta is absolutely unmissable.
The Saint-Gilles District: An Open-Air Museum
Why Saint-Gilles is the Heart of Art Nouveau
The municipality of Saint-Gilles, located south of the historic center, is undoubtedly the neighborhood with the highest concentration of Art Nouveau buildings in Brussels. Between the late 19th century and the early 20th century, Saint-Gilles became the preferred place for the progressive bourgeoisie, who commissioned emerging architects to design custom houses. Today, just getting lost in its streets will lead you to encounter dozens of decorated facades.
The main arteries to explore are:
Rue de la Victoire (Overwiningsstraat):Here you can find several buildings by Horta and his contemporaries.
Rue Faider:One of the streets richest in examples, with palaces from the early 20th century.
Rue Paul Emile Janson:Lined with houses of eclectic and Art Nouveau style.
Place Marie Janson (formerly Place Morichar):In the center, the fountain and some notable facades.
The Horta House (Maison Horta) – Museum
The most important work of Victor Horta is his own house and studio, located at number 23 Rue Américaine (Saint-Gilles). Today it is a visitable museum (entrance fee, but the facade is visible for free). The building, constructed between 1898 and 1901, is an absolute masterpiece. Inside, you can admire the original furnishings, the iron and glass spiral staircase, the stained glass with plant motifs, and the floor mosaics. For architecture enthusiasts, the guided tour is an unforgettable experience. Even just observing the exterior, with its play of asymmetric volumes and wrought iron railing, is already a pleasure.
The Ixelles District: Elegance and Refinement
Ixelles, bordering Saint-Gilles, offers another rich concentration of Art Nouveau buildings, often more stately and less dense. Ixelles was the preferred neighborhood of artists and intellectuals, and this is reflected in the more experimental architecture.
Rue de l'Aqueduc and Rue du Lac
A walk along Rue de l'Aqueduc and Rue du Lac allows you to admire:
Casa De Beck (Rue de l'Aqueduc, 51):By Auguste Lauwers, featuring a stunning asymmetric facade and an angular bay window.
Casa Hannon (Rue de la Jonction, 1):By Jules Brunfaut, with a Priave mosaic on the facade (visible from the street).
Casa Saint-Cyr (Rue de l'Aqueduc, 11):Considered one of the most extravagant facades, with a full-height balcony and geometric motifs.
Rue de la Paix
This small street in Ixelles is home to theCasa Cauchie (Rue des Francs, 5), a building with a facade entirely decorated by a large mosaic with an allegorical subject. The architect Paul Cauchie was also a painter and decorator, and his house is a unique example of a total work of art.
The Royal Quarter and the Center: The Cosmopolitan Art Nouveau
Even in the center of Brussels, near the Grand-Place and the Brussels Park, there are some notable examples:
Instrument Museum (Old England):Actually a building in Art Nouveau style from 1899, now home to the museum. The stained glass and the corner turret are spectacular.
Palace of Fine Arts (BOZAR):Opened in 1929, it is more Art Deco than Art Nouveau, but represents the subsequent evolution.
Royal Galleries of Saint-Hubert:Although they are from 1847 (before Art Nouveau), they influenced later architects with their stained glass.
Other Art Nouveau Architects in Brussels
In addition to Victor Horta, Brussels boasts other masters of Art Nouveau:
Paul Hankar
Hankar was a contemporary of Horta, and his house-museum (Rue de la Vallée, 7-9) is another key stop. Built in 1893, it is considered one of the first Art Nouveau houses in Brussels. The facade is made of white stone and wrought iron, with motifs of scrolls and female figures.
Gédéon Bordiau
Known for the Cinquantenaire Park, Bordiau used Art Nouveau in some secondary buildings of the park, such as the entrance pavilion.
Ernest Blérot
Author of numerous houses in the Saint-Gilles district, often with stucco and ceramic decorations.

Art Nouveau in Detail: What to Observe

Beyond Art Nouveau: Art Deco in Brussels
After World War I, Art Nouveau gave way to Art Deco, which is more geometric and less decorative. Brussels has notable examples, such as thePalace of Justice(even though it is eclectic), the1935 Expo pavilion, and thePalace of Fine Arts (BOZAR). Art Deco can also be admired in the neighborhood ofLaeken, with the Japan Museum and some private villas.

Free apps (e.g. "Art Nouveau Brussels") with geolocated routes and descriptive sheets.
Paper guides in art bookshops in the city center.
Heritage Days: A Unique Opportunity
Every year, on the third weekend of September, the Heritage Days (Journées du Patrimoine) take place, during which many private Art Nouveau buildings open their doors to the public for free. It is an opportunity to see normally inaccessible interiors, such as the De Beck House or the Cauchie House. Reservations must be made weeks in advance.
Practical Tips for Walks
Comfortable shoes:The streets are cobbled or paved with cobblestones, and you walk a lot.
Camera:Bring it, but respect the privacy of residents (do not photograph interiors from the outside without permission).
Clothing:Bring an umbrella or a rain jacket; walks can be interrupted by rain.
Hours:Many buildings can only be seen from the outside. Museums (Casa Horta, Casa Hankar) have limited hours, check online.
Offline maps:Download an offline map or an app, as data coverage is not always perfect in some residential areas.

An open-air history book of architecture
Walking through Art Nouveau in Brussels is like flipping through an open-air history book of architecture. Each facade tells the story of faith in progress, love for nature, and the limitless creativity of an extraordinary era. It's not just about seeing buildings, but immersing oneself in a lifestyle that celebrated beauty even in the smallest details: a handle, a step, a stained glass window.

Even if you are not an expert, let yourself be guided by the curves and colors. Stop in front of a door, observe the railing, look up at a bay window. Brussels will surprise you at every corner.
