The Sydney Opera House is part of the 7 Wonders of the World. Each country has its own landmark, architectural structure, which has become, as it were, the hallmark of a particular settlement. And it doesn't matter at all whether it is the majestic and ancient Colosseum or the modern, elegant Eiffel Tower, it is, first of all, a symbol. Speaking about Australia, and specifically about Sydney, the Opera House can be called the symbol of the city. Sydney, while not the capital of Australia, is by far the largest and oldest city in the country. Therefore, it is not surprising that this city was chosen as the site for the construction of such a grandiose structure. The place for the construction of the opera house in Sydney is also very interesting, the building is surrounded on three sides by water, which, in combination with interesting architecture, suggests associations with a large sailing ship. The territory of Cape Bennelong was chosen for the construction of the theater.
As a rule, for the construction of such a grandiose structure, it is customary to hold a competition and tender anywhere in the world to identify the most successful and original project. This was also the case with the Sydney Opera House, since the beginning of 1950 an international competition was held. Undoubtedly, a lot of bright, interesting and original projects were sent to the competition, but the qualified jury gave their preference to the project of the architect from Denmark Jorn Utzon. His project, among other things, was recognized as the most daring and original. But according to the architect himself, the idea came to him while walking along the Sydney embankment, the prototypes of the famous domes of the opera house were yachts moored in the bay. The second, quite an important factor, was that the project was easy enough to bring to life from an engineering point of view.
After the approval of the project, the start of construction was scheduled for mid-1959. It is noteworthy that it took 4 years of continuous work to erect only the foundation. This was followed by the stage of building the roof, which, for obvious reasons, became the most painstaking and time consuming. Additional difficulties arose due to the fact that structures of this kind had never been erected before, that is, everything had to be done for the first time, and not rely on the experience of predecessors. But the result is worth it, because it is the roof of the opera house that is a recognizable symbol not only of Sydney, but of the whole of Australia. The roof frame consists of 2, 000 concrete sections, which are assembled together using steel cables. On top of this structure, the roof is clad with white and beige ceramic tiles. The use of tiles of several colors at once creates an interesting effect of movement.
As with any long-term project, the Sydney Opera House has undergone a number of significant changes during construction. So in 1966 its creator left the project, and the work was continued by the Australian architects, who had previously worked in the team of Jorn Utzon. It was only by 1967 that all external work was completed, but it took another 6 years to bring the structure to perfection, to complete all the finishing and decorating work.
Finally, in 1973, the Sydney Opera House was opened by Elizabeth II herself. According to the project, there are four stages in the building. The total height of the building is 67 meters. The main hall has a capacity of 2, 600 seats. It is noteworthy that in the 20-year history of the opera house, more than thirty-five million people have visited it, while the population of Australia is only twenty-three million people.
