Exterior
The wing's façade on the court side, now the Cour Carrée, consists of two main stories (ground floor and first floor) plus an attic richly decorated with Jean Goujon's bas-relief sculptures. It is crowned by a sloping or Mansard roof, which had considerable influence on the subsequent development of French architecture, including the later work of François Mansart which gave his name to the roof profile. The deeply recessed arch-headed windows of the ground story form an arcade, while the projecting pavilions bear small round oeil de bœuf windows above them. In the second storey slender fluted pilasters separate the windows, which alternate triangular and arched pediments. Goujon's sculpture and architectural ornaments are subordinated to the construction. 
The eastern façade was comprehensively renovated in the early 1980s and inaugurated by President François Mitterrand, together with the rest of the cleaned-up Cour Carrée, on 24 February 1986.
