Who designed the Palais de la Bourse in Paris?

The Palais de la Bourse in Paris was designed by Alexandre-Théodore Brongniart.

Napoleon commissioned Brongniart in 1807 to create a monumental home for the Paris stock exchange. Construction began in 1808, producing a severe Neoclassical building surrounded by a continuous colonnade. Its formal design reflected the era’s interest in presenting commerce as an organized and powerful civic institution.

Brongniart died in 1813, before the building was finished. Architect Éloi Labarre took over the work, and the completed structure opened in 1826. Because Labarre completed the project, some descriptions mention both architects, but Brongniart remains the canonical designer and the building is now known as the Palais Brongniart.

The answer is sometimes confused with other Parisian architects. Jean-François-Thérèse Chalgrin designed the Arc de Triomphe, Charles Garnier designed the Paris Opera, and Jacques-Germain Soufflot designed the Panthéon. None of them designed the former Paris stock exchange.
