Fodor's Expert Review Grand Palais Éphémère

This soaring 2½-acre structure—a stand-in for the original across the Seine while it undergoes massive renovations—was designed by Paris architect Jean-Michel Wilmotte as a contemporary, and temporary, rendering of its namesake. Taking pride of place at the foot of the Eiffel Tower's Champs de Mars, the wood-and-transparent-plastic edifice is home to everything from blockbuster art exhibitions and art fairs to concerts, fashion shows, and sporting events. It will also host some of the 2024 Paris Olympic and Paralympic Games.
