Sydney's Siren

185 meters long and 125 meters wide, 1000 rooms, 1 million danish roof tiles, 6225 Sq meters of glass, roof sections weigh 15 tons a piece, 102M dollars to build and the architect quit halfway through the project, but the Sydney Opera house still was erected and is one of the most recognizable pieces of architecture in the world today. And I must say, It doesn't disappoint.
