The Sydney Opera House roof is one of the most iconic and recognisable structures in the world. It is a marvel of engineering and design, and its construction was a major undertaking.
The roof is made up of 2,194 precast concrete shells, each weighing up to 15 tons. The shells are arranged in a complex pattern that creates the distinctive sail-like shape of the roof.
The concrete shells were cast in a specially designed factory on-site. Each shell was then lifted into place by a crane and secured to the steel framework of the roof.
The roof is covered with a layer of white ceramic tiles. The tiles were specially designed to reflect the sun's heat and keep the interior of the Opera House cool.
The Sydney Opera House roof is a masterpiece of engineering and design. It is a testament to the skill and creativity of the architects and engineers who worked on the project.
