Erected for the 1900 Exposition Universelle (World’s Fair), the Grand Palais is topped by a huge 8.5-tonne art nouveau glass roof. It hosts some of Paris’ biggest art exhibitions, but its role as a 2024 Olympic venue has seen it close for renovations until 2024. During its closure, a temporary Grand Palais will set up on the Champ de Mars adjacent to the Eiffel Tower.
