The Théâtre des Folies-Marigny, a former Parisian theatre with a capacity of only 300 spectators, was built in 1848 by the City of Paris for a magician named Lacaze and was originally known as the Salle Lacaze. It was located at the east end of the Carré Marigny of the Champs-Élysées, close to the Avenue Marigny, but faced west toward the Cirque National on the other side of the square.
