For an exceptional look at one of Brussels’ finest Art Nouveau buildings, head to the Maison St. Cyr. This ornate, narrow house was designed by Belgian architect, Gustave Strauven, who worked for the father of Art Nouveau, Victor Horta, from the age of 18. The house was built between 1901-03 as the residence of Georges de Saint-Cyr. The building has been recently restored, however, as it is up for sale, it is not possible to visit inside. While in the neighbourhood, wander through the lovely Square Ambiorix, where you will find many other beautiful houses circling a vibrant city park.
