Atrium
Valadier’s original simple facade was added to with a majestic pronaos, porticoed on the ground floor, open in a loggia on the first floor, and crowned by a triangular pediment.
The lower section of the forepart has a base made of smooth ashlars that imitate travertine, and forms a covered atrium that allowed carriages to pass through.
Today it is home to the bookshop.
