All the atmosphere of an 18C residence captured on the first floor of this mansion where art and history come together: numerous furnishings stamped by the creators reveal the refinement of this time. On the ground floor, works of art dating from the 16C to 20C, by Houdon, Pajou and JB Lemoyne. One of the museum's 35 rooms is dedicated to the murder of Marat by Charlotte Corday, another to the declaration of human rights.
