Situated in the 9th Arrondissement of Paris, next to the Opéra Garnier, Galleries Lafayette Haussmann is an architectural marvel thanks to its Art Nouveau décor. The grandiose department store is an essential stop for shopaholics and those who want to spend lavishly. It is a shoppers’ paradise all year round, but during the winter months, many people visit the place just to feel the magic of Christmas.
