Victor Horta's houses in Brussels: the UNESCO masterpieces
Brussels: Art Nouveau Brussels Tour
Which Victor Horta houses can you visit in Brussels?
The Horta Museum (his own house and studio in Saint-Gilles) is open to the public most days. Four Horta townhouses are UNESCO World Heritage — Hôtel Tassel, Hôtel Solvay, Hôtel van Eetvelde and the Horta House/studio. Tassel, Solvay and van Eetvelde are mostly admired from outside or via occasional special openings and guided tours.
The man who invented Art Nouveau architecture
Victor Horta (1861–1947) is the reason Brussels matters in the history of design. His 1893 Hôtel Tassel is widely held to be the first true Art Nouveau building, and over the following decade he produced a series of townhouses so revolutionary that four are now UNESCO World Heritage. His innovation was the open, light-filled interior — banishing the dark, boxed-in rooms of the typical Brussels terraced house in favour of flowing space organised around a sculptural iron staircase and a glass roof. This guide covers his key houses and how to see them. For the wider movement, see our Brussels Art Nouveau guide.
The four UNESCO-listed houses
In 2000, four Horta townhouses were inscribed together as a single UNESCO World Heritage site:
1. Hôtel Tassel (1893)
The one that started it all — built for scientist Émile Tassel. Its iron “whiplash” staircase and open plan broke every rule. The exterior is admirable from the street (Rue Paul-Emile Janson); the interior opens only rarely or via special tours.
2. Hôtel Solvay (1894–1903)
A lavish mansion for the wealthy Solvay family, where Horta designed everything — furniture, carpets, cutlery — as a total work of art. One of his most opulent interiors; it opens occasionally (check schedules and special openings).
3. Hôtel van Eetvelde (1895–1901)
Built for a colonial administrator, notable for its dazzling glass-domed octagonal hall and exposed metal structure. Admired mostly from outside, with limited access.
4. The Horta House & Studio (1898–1901) — now the Horta Museum
Horta’s own home and workshop in Saint-Gilles, and the one you can reliably visit. Preserved as a museum, it lets you walk through his masterpiece — the famous staircase, the light well, the original furniture. See our dedicated Horta Museum guide.
What you can actually visit
| House | Access |
|---|---|
| Horta Museum (his house/studio) | Open most days to the public |
| Hôtel Solvay | Occasional openings / special tours |
| Hôtel Tassel | Exterior; rare interior access |
| Hôtel van Eetvelde | Exterior; limited access |
The reliable interior is the Horta Museum. To get inside the others, time your visit for heritage days or the spring BANAD festival, when many private Art Nouveau interiors open, or join a guided tour with arranged access.
Beyond the four: more Horta in Brussels
- The Comics Art Museum is housed in Horta’s former Waucquez textile warehouse — a free way to experience a Horta interior (with comics on top!).
- The Hôtel Hannon and other works dot the southern districts.
- His influence radiates across Saint-Gilles and Ixelles, where his pupils and contemporaries built whole streets of Art Nouveau (walking route).
How to see them best
The houses are scattered across Saint-Gilles and Ixelles, and the access rules are fiddly — which is exactly where a guide helps. A 3-hour Art Nouveau tour walks you between the Horta masterpieces with expert context, a combined pass-style tour can bundle interior visits, and a local-led walk adds the human stories. See best Art Nouveau tours.
Start with the Horta Museum — it’s the only Horta interior you can count on, and it’s a genuine masterpiece. Then walk the surrounding streets and let the façades do the rest.
