The characterizations are: the use of industrial materials like steel and iron in the visible parts of houses, new decorations inspired by nature (e.g. the famous whiplash motive, which occurs very often in the Art Nouveau style and especially in the work of Horta), decorative mosaics or sgraffito on the facades of houses, etc...
Most of these principles can be seen applied in the Horta Museum itself. This house also shows one of the great innovations of Horta: the rooms are built around a central hall. From the beautiful glass ceiling light falls into the house and thereby creating a much more natural illumination of the building than was the case in the traditional late 19th century houses in Brussels and Belgium.
The Horta Museum (French: Musee 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 (1898) in the Brussels municipality of Saint-Gilles.
In the splendid Art Nouveau interiors there 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 UNESCO World heritage list.
