Berlin has three major opera houses: the Deutsche Oper, the Berlin State Opera, and the Komische Oper. The Berlin State Opera on Unter den Linden opened in 1742 and is the oldest of the three. Its musical director is Daniel Barenboim. The Komische Oper has traditionally specialized in operettas and is also at Unter den Linden. The Deutsche Oper opened in 1912 in Charlottenburg.
