Put together by Count Moïse de Camondo, this collection is named after his son Nissim, who was killed in World War I. Moïse replaced the family's two houses near Parc Monceau with this palatial residence and lived here in a style in keeping with his love of the 18th century. Grand first-floor reception rooms are filled with furniture by craftsmen of the Louis XV and XVI eras, silver services, Sèvres and Meissen porcelain, Savonnerie carpets and Aubusson tapestries.
