Now that Spring is in the air, I decided to go for a stroll round Brussels to view the exterior facades of the 4 inscribed town houses of Horta and other main Art Nouveau sites in Brussels. The only town house that is open on a regular basis is the Horta Museum, however when there is the Art Nouveau Biennale, the other town houses are opened to the public and can also be visited with the Biennale registered tour guides (like I did in 2011 when I visited Hotel Tassel and Hotel Solvay). Here are a few addresses that might come in handy should you be in Brussels:

- Maison & Atelier Horta Museum (open from 14:00 to 17:30) = Rue Americaine 25, 1060 Brussels

- Hotel Tassel = Rue Paul Emile Janson 6, 1050 Brussels

- Hotel Solvay = Avenue Louise 224, 1050 Brussels

- Hotel Van Eetvelde = Avenue Palmerston 2-6, 1040 Brussels

Top Art Nouveau sites in Brussels worth visiting:

- Maison St. Cyr = Ambroix Square 11, 1000 Brussels

- Musical Instruments Museum (MIM) = Rue Montagne de la Cour 2, 1000 Bruxelles

- Maison Max Hallet = Avenue Louise 346, 1050 Brussels

- Maison Ciamberlani = Rue Defacqz 48, 1050 Brussels

- Place Saint Boniface = several Art Nouveau buildings
