Sydney is the capital of the Australian state of New South Wales, and the largest city in the country of Australia. It is a beautiful, coastal, cosmopolitan area; and home to two of Australias most famous landmarks - the Sydney Opera House and the Sydney Harbor Bridge. The Opera House was designed by the Danish architect Jorn Utzon as the result of an international competition that started in 1955. It was not completed until 1973. The Sydney Harbor Bridge is the largest steel arch bridge in the world with a span of 1,650 feet and a total length of over 3,700 feet.
