It’s an easy walk from the Duomo, through the Galleria and on to La Scala, Milan’s famous opera house which opened in 1778. Here some of the world’s best singers and orchestras can be heard and famous ballets seen. If you cannot book tickets to one of the performances, a visit to the Museo Teatrale alla Scala ( Museum) also includes a visit to one of the boxes where you can look down on the stage.
