How did the sydney opera house come about?

the sydney opera house is called the sydney opera house because opera is song in the building and because of its great views.

What goes on inside the Sydney Opera House? THere are many performances. Singing, dancing, school concerts, orchestras, etc.

Because it is unique,and it must be the most recognisable biulding in the world. It required new and untried construction methods. To me, its awsomely beautilul.

it is 161,542,952 tons heavy

I think it is around 2000m long I think
