The Halle aux blés (Wheats Exchange or Grains Exchange) was a circular building in central Paris used by grain traders built in 1763–1767, with an open-air interior court that was capped by a wooden dome in 1783, then by an iron dome in 1811. In a major reconstruction in 1888–1889 much of the structure was replaced and the building became the Bourse de commerce.
