Solvay House (Brussels)

View of the spectacular staircase. At the back you see a painting by Théo Van Rysselberghe. To the left is the dining room, to the right the billiard room. Built by Victor Horta between 1895 and 1900 for Armand Solvay, this is a Unesco World Heritage Monument. The house is still a private property, but can be visited.
