Sydney Opera House — Sydney, Australia
Sydney Opera House is probably one of the most beautiful buildings we've ever witnessed. It sits like a jewel in Sydney harbour and dazzles everyone that walks by... If you ever get the chance to watch the sun set whilst sat under it's huge wing-like arches then you should take it.
The Sydney Opera House is free to enjoy from the outside, but you can also experience a guided tour for a fee - something we TOTALLY regret not doing but time was tight on our trip.
