Situated across the Plaza de Oriente from the Palacio Real, the Teatro Real Madrid is a center for opera and ballet performances. Antonio López Aguado designed the theater for Queen Isabel II in 1818, but construction on the hexagonal building was postponed. Then, quickly built over just five months in 1850, the opera house opened with Gaetano Donizetti’s La Favorita. In 1969, it hosted the Eurovision song contest featuring a Dalí sculpture on stage. A later renovation revamped the venue, and there are daily tours through the dressing rooms and auditorium.
