Which neoclassical building in Paris was originally a grain market?

The neoclassical Paris building originally associated with a grain market is the Bourse de Commerce.

Its history begins with the Halle aux blés, or Wheat Exchange, a circular building constructed from 1763 to 1767 for storing and trading grain. The original structure had an open central courtyard and later gained a wooden dome, which was replaced after a fire by an iron-and-copper dome designed by François-Joseph Bélanger.

The grain exchange closed in 1873, and the building was substantially reconstructed in 1888–1889 by Henri Blondel as the Bourse de Commerce, or Commodities Exchange. Much of the earlier fabric changed, but the circular plan, dome, and historic connection to grain trading remained central to its identity.

“Les Halles” can be confusing because it names the broader historic market district nearby, while the Bourse de Commerce is the specific building. Since 2021, the restored landmark has housed the Paris exhibition space of the Pinault Collection.
