Major town houses of the architect Victor Horta (Brussels)

Four Brussels town houses by Victor Horta, UNESCO-listed since 2000.

Victor Horta’s four major town houses in Brussels, Belgium, have been a UNESCO World Heritage Site since 2000. Each was designed and built by Horta, the Belgian architect who helped launch the Art Nouveau movement in the mid-1890s.

Horta was born in Ghent in 1861. After a few years in Paris, he returned to Belgium in 1880 to work as an architect. He rose quickly, landing prestigious commissions and official roles, including a post at the Free University of Brussels. In 1892 he began working in the new Art Nouveau style. The following year he designed the Hôtel Tassel, widely regarded as one of the first Art Nouveau buildings—alongside Paul Hankar’s Hankar House, built around the same time. Horta used the same approach for many later projects, such as the Hôtel Solvay (1895–1900), the Hôtel van Eetvelde (1895–1901), and his own house and workshop (1898–1901). Architects like Antoni Gaudí and Hector Guimard drew inspiration from Horta’s work during this period.

During World War I, Horta lived in exile in the United Kingdom and the United States. After returning to Belgium, he shifted away from Art Nouveau toward Art Deco or Modernist styles, adapting to changing tastes. He died on 8 September 1947 and was buried in Ixelles Cemetery in Brussels.

The UNESCO listing includes four houses: Hôtel Tassel, Hôtel Solvay, Hôtel van Eetvelde, and Maison & Atelier Horta. Other notable surviving examples of Horta’s Art Nouveau work in Belgium—such as the Hôtel Max Hallet (1903–1906) and the Magasins Waucquez (1905–1906), now the Belgian Comic Strip Center—are not part of the listing.

UNESCO recognized the four houses in 2000, calling them pioneering works of late-19th-century architecture. The commission noted their open floor plans, diffusion of light, and the seamless integration of curved decorative lines with the building structure. The houses were chosen for both their architectural significance and their good state of preservation.

Lore & Background

Victor Horta was born in Ghent, Belgium, in 1861 and lived for several years in Paris before returning to Belgium to work as an architect in 1880. He achieved rapid success, working on several prestigious buildings and receiving a number of official posts including a position at the Free University of Brussels. From 1892, Horta began working in the new Art Nouveau style. In 1893, he designed the Hôtel Tassel, which is considered one of the first examples of Art Nouveau architecture (along with the Hankar House by Paul Hankar, built at the same time). He applied the same style to many subsequent buildings, including the Hôtel Solvay (built 1895–1900), the Hôtel van Eetvelde (1895–1901), and his own house and workshop (1898–1901). Among the architects who were inspired by Horta's works of the period are Antoni Gaudí and Hector Guimard.

Reader's Guide

The four major town houses—Hôtel Tassel, Hôtel Solvay, Hôtel van Eetvelde, and Maison & Atelier Horta—are some of the most remarkable pioneering works of architecture of the end of the 19th century. The UNESCO commission recognized them in 2000, noting that the stylistic revolution represented by these works is characterized by their open plan, the diffusion of light, and the brilliant joining of the curved lines of decoration with the structure of the building. The four houses were selected on the basis of their architectural importance but also because of their state of conservation. During World War I, Horta went into exile in the United Kingdom and the United States. On returning to Belgium, he modified his styles in subsequent buildings, moving away from Art Nouveau towards Art Deco or Modernist styles to take account of changing popular tastes. He died on 8 September 1947 and was interred in Ixelles Cemetery in Brussels.
