Paul Marmottan had a passion for the arts of early 19th century France and set out to decorate his townhouse in the corresponding Empire style. The rooms he furnished have been perfectly preserved and showcase paintings, sculptures, decorative objects and furniture by the greatest names of the period, among them: Jean Joseph Xavier Bidault and Carle Vernet, François-Xavier Fabre, Jacques Augustin Catherine Pajou, Antonio Canova, Pierre Antoine Bellangé, Georges Jacob and Pierre Philippe Thomire.
The Museum is also noteworthy for a rare ensemble of portraits by Louis Boilly, an artist of whom Paul Marmottan was not only a collector but also the biographer.
