Read the passage and do the tasks that follow. The Sydney Opera House The Sydney Opera House is built on Bennelong Point, in Sydney Harbour, close to the Sydney Harbour Bridge. The first known concert on Bennelong Point was held in March 1791. Public pressure to build a suitable concert facility in Sydney became greater in the 1940s. In 1955, the New South Wales government announced an international competition for the design of “an opera house”. Danish architect Jørn Utzon’s entry was selected as the winning design. His design was for a complex with two theatres side by side on a large podium. This was covered by interlocking concrete shells, which acted as both wall and roof. A third smaller shell set apart from the others was to cover the restaurant. The construction of the Opera House was sometimes difficult and controversial with Jorn Utzon resigning from the project in 1966. However, the Opera House was officially opened by Queen Elizabeth II on 20 October 1973. The Sydney Opera House became a UNESCO World Heritage Site in 2007.
