The Theatre Royal was built by order of King Emmanuel III of Savoy, who entrusted the project to the court architect Benedetto Alfieri, on an area already earmarked for theater in Amedeo di Castellamonte for the central zone (1673) and the same space covered by a previous project of the architect Filippo Juvarra. Was inaugurated in 1740: the Horseshoe lounge, whose time was painted by Bernardino Galliari, housed in stalls and in five tiers of boxes over 2500 spectators. During two centuries became one of the most important theatres in Europe and, at the turn of the twentieth century, one of the strongholds in Italy, even Wagnerian thanks at the top reached by the Orchestra under the artistic direction of Arturo Toscanini. In 1936 a disastrous fire destroyed the structure, and in 1973 was inaugurated the new Teatro Regio, Turin realized by the architect Carlo Mollino. Today the Royal is the Temple of Opera and music Turin hosts major orchestras and dance companies nationally and internationally.
