Without a doubt, the most important building in Sydney is the Opera House. This is the traditional backdrop for "I was in Sydney" selfie.
The Opera House, a well-known symbol of Sydney, houses many concert halls and other art venues. The building is considered a masterpiece of the 20th-century architecture, one of the most famous in the world.
Danish architect Jørn Utzon was looking for a simple geometric principle for his design. His team of architects proposed a solution based on a spherical concept with arches of different lengths. This makes it possible to arrange arch segments next to each other. The final result we can admire are spherical cross-sections that are stacked on top of each other and diverge in two opposite directions.
