The Epermon Staircase

The Epermon Staircase leads from the first floor - with direct access from the King's private chambers - to the second floor where it leads out into Madame du Barry's chambers. The staircase is designed with the characteristic simplicity that implies that it would not have been used by other than the King and his most intimate relations - notice that the steps themselves are made of wood rather than stone as is otherwise the norm.
