(b. 1739, Paris, d. 1811, Paris)
Palais du Luxembourg, Paris
Chalgrin, who had successfully continued his professional career from the Ancien Régime into the Empire era, was involved into the extension of the Senate in the Palais du Luxembourg, where he had previously worked in 1787. The new staircase, which occupied the space of the Medici Gallery decorated by Rubens, was given a classical look with continuous three-quarter Ionic columns and coffered barrel vaulting.
