One of the 20th century’s architectural icons was unveiled to the world on this day in 1973 when the Queen opened the Sydney Opera House.
It had taken more than 16 years to build, phenomenal engineering innovations, some notorious political infighting and even street demonstrations across the city when the original architect resigned in 1966. Because Sydney wouldn't be the same without the Opera House, we're marking the opening of this great building with a musically named and very Australian Waltzing Matilda.
