The Théâtre national de Chaillot was built between 1934 and 1937 by the brothers Jean and Édouard Niermans for the Paris Exhibition of 1937 on the site of the former Trocadéro Palace, itself an elaborate structure built for the Paris World's Fair of 1878. Starting in 1973 the interior of the theatre was completely renovated by the team of Valentine Fabre and John Perrottet and now houses a theatre school and three theatre venues: the Salle-Jean Vilar with 1250 seats, the Salle Gémier with 420 seats, and an 80-seat studio dedicated to small productions and avant-garde shows.
