Sydney Opera House can be called without exaggeration one of the most recognizable buildings in the world - who among us did not see these sky-scraping sails, or orange slices that grow directly from the waters of the Sydney harbor? Opened in 1973 by Queen Elizabeth II herself, today this musical theater is a true symbol of Australia. Interestingly, once in this place at Bennelong Point were located first a fort, and then a tram depot, until in 1958 it was decided to build a theater.
