Maison Saint-Cyr is a private house on Square Ambiorix in Brussels, designed by Gustave Strauven and completed in 1903. Its narrow facade packs in Art Nouveau detail: wrought-iron balconies, stained glass, colorful surfaces and flowing lines. Look closely at the balcony balustrades, each with its own pattern of curves and shapes. The house was built as a residence for artist and decorator Léonard de Saint-Cyr. You can admire the architecture from outside; there is no interior access.
A narrow facade by Gustave Strauven

Maison Saint-Cyr stands on Square Ambiorix in Brussels. Gustave Strauven designed it as a residence for artist and decorator Léonard de Saint-Cyr. The house was built between 1900 and 1903 and completed in 1903.
Strauven was a student of Victor Horta. On this narrow facade, he gave the ironwork a prominent role, pairing it with glass, color and curving forms. The result is a compact composition that rewards a close look from the square.
Look closely at the balconies

The wrought-iron balconies are among the facade’s most individual details. Each balustrade has a different arrangement of lines, curves and geometric shapes, with patterns that recall intertwined plants and branches. The window decorations also follow Art Nouveau’s flowing forms, while stained glass adds another detail to pick out from outside.
Take time to compare the balconies rather than viewing the facade as a single ornamented surface. The house’s narrow frontage concentrates its decoration, so smaller elements can be easy to miss at a glance.
Viewing the house from outside
Maison Saint-Cyr is a private residence, so visitors cannot go inside. Plan your stop around the exterior: view the facade in daylight, then change your position to see how the balcony ironwork and window details read from different angles. Photography is limited to outside views.
The house is in the Quartier des Squares, away from Brussels’ main tourist circuit. If you are making a special trip, plan another activity nearby or combine it with a wider walk through the city.
