The Sydney Opera House is, without question, an icon of the city. It was declared a World Heritage Site in 2007 and was built in 1957 under the direction of architect Jon Utzon. It is a modernist work and consists of several overlapping shells - an innovative piece of work that had a great impact worldwide on architecture. It was opened by Queen Elizabeth II of England. The Opera House shows a variety of opera, ballet, music and theater productions. It is home to the Sydney Symphony Orchestra. You can visit from 8:30 to 17:00 and take a guided tour, provided that there are no shows on.'http://www.rodamons.net'
