Bourse de commerce

The Bourse de commerce is a building in Paris, France, originally used as a place to negotiate the trade of grain and other commodities, now used to provide services to businesses by the Paris Chamber of Commerce. It has its origins in a circular corn exchange built in 1763–67, with an open-air interior court that was capped by an iron dome in 1811. In a major reconstruction in 1888–89 much of the structure was replaced, although the layout remained the same and the dome was retained with modifications. The dome of the building is listed as a historical monument.
Between 1574 and 1584 Jean Bullant built a hôtel particulier on the site for Catherine de' Medici . A tower with an encaged observation platform, now called the Medici column, was built beside the hôtel from which observations of the stars could be made for astrological purposes. The Queen's hôtel was bought by Charles de Bourbon-Condé, Count of Soissons, who repaired and enlarged it. The hotel became called the Hôtel de Soissons. The indebted last owner was Victor Amadeus of Savoy . After his death the hotel was demolished in 1748 and the materials sold to pay the creditors. The city of Paris bought the column from its first owner, Laurent Destouches, which saved it from destruction.
