The incredibly beautiful opera is located on the coast of Point Bennelong and is one of the emblems of Sydney. It was opened on 20 October 1973 personally by Queen Elizabeth II with a performance of Beethoven's Ninth Symphony and splendid fireworks. The building of the Sydney Opera House includes about a dozen rooms of different sizes for different kinds of cultural events - a concert hall with 2500 seats, Drama Theatre with 500 seats, as well as several small rooms, one of which is located in the inner open-air courtyard. The roof is composed of structures that are called "shells” and resemble sails. They give a unique look of the building and make it unlike any building in the world. The opera is one of the most famous buildings in the world and is one of the main attractions of Australia. Sydney Opera House is also recognized as one of the most remarkable facilities in modern architecture.
