Spiralstaircase in the Bourse de commerce_Paris

The former hall was closed in 1873, handed over to the Chamber of Commerce in 1875 and reopened as a stock exchange in 1888/89 after a renovation by Henri Blondel. The inner courtyard of the circular building was redesigned and the brickwork was clad with local stone. The dome and the painting have been listed since 1975. Following extensive restoration in 1989, smaller trade fairs and exhibitions are held in the covered inner courtyard. Quote: Wikipedia
