Sydney Opera House
Designed by Danish architect Jørn Utzon, the Sydney Opera House is perhaps one of the most widely recognized buildings in the world. The complex, which contains a concert hall and several theaters, was the result of an international design competition held in 1956. Utzon's design featured a series of precast concrete shells that create a unique sail-like effect. Completed in 1973 following the resignation of Utzon during construction, the Opera House stands today as an elegant presence on the Sydney waterfront.
