The luxurious theater was inaugurated on January 27, 1925 with the performances of the operetta Madame Pompadour of Leo Fall and capacity for more than eight hundred spectators. Although much of its history has been linked to the genre of the Spanish music reviews (with divas such as Celia Gámez, Lina Morgan or Esperanza Roy), at the beginning of the thirties it functioned as a movie theater, being one of the first rooms that incorporated sound projector. In 2012, the Teatro Alcazar was renamed the Teatro Cofidis Alcazar for its sponsor.
