This building, designed by the architect Baudet, is an example of the use of wrought iron that breaks the monotony of the stone façade. At the time, metal was the most modern material. From the mid-nineteenth century onwards industrial art enhanced the quality of buildings with its decorative modernity such as the ornamental cast iron which was used from the early nineteenth century. Iron work even incorporates the principles of hierarchy and the register of stone sculpture. You will find it here in the railing, pelmets and balconies.
