UNESCO Description of the World Heritage Site

The four major town houses - Hôtel Tassel, Hôtel Solvay, Hôtel van Eetvelde, and Maison & Atelier Horta - located in Brussels and designed by the architect Victor Horta, one of the earliest initiators of Art Nouveau, are some of the most remarkable pioneering works of architecture of the end of the 19th century. The stylistic revolution represented by these works is characterised by their open plan, the diffusion of light, and the brilliant joining of the curved lines of decoration with the structure of the building.

UNESCO Justification of the World Heritage Site

Criterion (i): The Town Houses of Victor Horta in Brussels are works of human creative genius, representing the highest expression of the influential Art Nouveau style in art and architecture.

Criterion (ii): The appearance of Art Nouveau in the closing years of the 19th century marked a decisive stage in the evolution of architecture, making possible subsequent developments, and the Town Houses of Victor Horta in Brussels bear exceptional witness to its radical new approach.

Criterion (iv): The Town Houses of Victor Horta are outstanding examples of Art Nouveau architecture brilliantly illustrating the transition from the 19th to the 20th century in art, thought, and society.

Encyclopedia Record: Hôtel Solvay

The Hôtel Solvay, also known as the Solvay House, 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.
