Between 1894 and 1898, this most prestigious of Art Nouveau mansions was built to the designs of Victor Horta for Armand Solvay, son of the famous industrial magnate, on what was then a grandiose avenue. Horta was given an unlimited budget, and created an interior full of visual fireworks, using noble and precious materials. The range of red and orange hues reinforces the luxurious and comfortable atmosphere. The building is a UNESCO World Heritage Site.
