Must see: Sydney Opera House

Arguably the most recognizable building in the world, The Sydney Opera House, was designed by architect Jorn Utzon in 1957. The inspirational series of roof shapes create a monolithic form that draws visitors toward it from land and sea. The view of the sail-like roof forms from the Manly ferry is undeniably beautiful as the building appears to float on water. It is approximately 185 m (611 ft) long and 120m (380 ft) wide at its widest point. The highest roof vault (above the Concert Hall) is 67m (221 ft) above sea level. Approaching the Opera House by foot is just as rewarding. The stairs cascade down the front of the building are faced with pink aggregate granite which was quarried at Tarana in New South Wales. 

There are a number of restaurants on the bridge side of the Quay with a view of the Sydney Opera House, however Aria has an amazing, sweeping view of The Opera House and the Harbour Bridge from their main dining room.
