Theater museum La Scala

The Museo Teatrale alla Scala is a theatrical museum and library attached to the Teatro alla Scala in Milan, Italy. Although it has a particular focus on the history of opera and of that opera house, its scope extends to Italian theatrical history in general, and includes displays relating, for example, to the commedia dell'arte and to the famous stage actress Eleonora Duse.

The museum, which is adjacent to the opera house in the Piazza della Scala, was opened on 8 March 1913 and was based on a large private collection which had been purchased at auction two years earlier, with funds raised both from government and private sources. The displays include costumes, set designs, autograph scores, and musical instruments of historical interest as well as paintings of musicians and actors, and a range of related paraphernalia including precious ceramic figures portraying characters from the commedia dell'arte, and board games which used to be played in the theatre's foyer.
