Where is it? East Circular Quay, on Sydney Harbour
Swarms of tourists surround the Opera House, joggers run up and down its stairs and many drink at its fantastic outdoor bar. People gawp at its incredible tiled sails, but many don’t venture inside the House to check out its equally awesome interior (even the toilets are cool). There are behind-the-scenes tours available, but to experience the Opera House the way it was intended, it pays to see a performance. As well as opera, there is a steady schedule of theatre, music, dance, talks and contemporary performance. Make it a rule to see at least one thing here per year.
