For many years there was no good opera house in Australia. In 1954, Jorn Utzon from Denmark( win,won,has won,was winning) a competition organized by the Australian government to build an opera house. The construction took fourteеn years and the project (has finished,finished,finishes,was finished) only in 1973.
Since then, the building (has become, became,was becoming, is becoming) the symbol of Australia. It is also(it*s,its,his,it) most famous landmark. The(more good,good,best,better) way to visit the Sydney Opera House is to see a show. In sunny weather visitors can take a picnic basket and enjoy walking around the Botanic Gardens near the Opera House.
