The Hôtel Solvay is a large historic town house in Brussels, Belgium. It was designed by Victor Horta for Armand Solvay, the son of the chemist and industrialist Ernest Solvay, and built between 1895 and 1900, in Art Nouveau style. It is located at 224, avenue Louise/Louizalaan, not far from the Hôtel Max Hallet, another remarkable Art Nouveau building by Horta.
Together with three other town houses of Victor Horta, including Horta's own house and workshop, it was added to the UNESCO World Heritage list in 2000 as the core of epoch-making urban residences that Horta designed before 1900.
The town house can be visited with a guided tour that needs to be arranged in advance.
