The Horta Museum (French: Musée Horta, Dutch: Hortamuseum) is a museum dedicated to the life and work of the Belgian Art Nouveau architect Victor Horta and his time. The museum is housed in Horta's former house and atelier, Maison & Atelier Horta (1898), in the Brussels municipality of Saint-Gilles. Housed in the Art Nouveau interiors is a permanent display of furniture, utensils and art objects designed by Horta and his contemporaries as well as documents related to his life and time. The museum also organises temporary exhibitions on topics related to Horta and his art. The building is inscribed on the UNESCOWorld Heritage List as one of the major town houses of Victor Horta in Brussels.
The UNESCO commission recognized the Horta Museum as UNESCO World Heritage in 2000.
The four major town houses - Hôtel Tassel, Hôtel Solvay, Hôtel van Eetvelde, and Maison & Atelier Horta - located in Brussels and designed by the architect Victor Horta, one of the earliest initiators of Art Nouveau, are some of the most remarkable pioneering works of architecture of the end of the 19th century. The stylistic revolution represented by these works is characterised by their open plan, the diffusion of light, and the brilliant joining of the curved lines of decoration with the structure of the building.
