After 15 years of construction, the Sydney Opera House is dedicated by Queen Elizabeth II. The $80 million structure, designed by Danish architect Jorn Utzon and funded by the profits of the Opera House Lotteries, was built on Nennelong Point, in Sydney, Australia. Famous for its geometric roof shells, the structure contains several large auditoriums and presents an average of 3,000 events a year to an estimated two million people. The first performance in the complex was the Australian Opera's production of Sergei Prokofiev's War and Peace, which was held in the 1,547-seat Opera Theatre. Today, the Opera House remains Sydney's best-known landmark.
