The Sydney Opera House is one of the most recognized architectural buildings standing in the world today. The design of the building was actually won by Jorn Ulzon design contest that the NSW Government held in 1956.
The construction included three stages that began with Stage 1 initiation in 1959. This stage is known as the "podium stage" in which the foundation and the columns to support the roof were laid. The team however was subdued to elemental delays that pushed the completion date back quite a bit.
The second stage is known as "Stage II: Roof" when obviously the roof was constructed. The roof is most defining visual aid of the building due its unique "shell" design. At the time the engineering of the "shells" proved most difficult and was actually one of the first times computers were used to aid in architecture. The design and process of the shells are what easily declared The Opera House a piece of modern art.
The third and final stage, "Stage III: Interior," also came with some controversy. With a new government and program overseeing the project, Ulzon decided to resign and changes were made. These changes included; the major hall design, cladding and paving to the podium, glass walls, and perspex rings.
The Sydney Opera House remains a major piece of modern art today. It has received several recent awards and was the icon of the Sydney Olympic Games.
