Galerías Lafayette sits next to the Opéra Garnier and is a department store selling fashion, cosmetics and jewellery. Its large Art Nouveau glass dome and rooftop terrace overlooking Paris and the Eiffel Tower are its defining features. The rooftop terrace is free to enter, and elevators and escalators connect every floor. Because of the number of visitors, the passage where people photograph the dome up close can involve waits of over 30 minutes.
