The Sydney Opera House is a masterpiece of late modern architecture by Jørn Utzon that pushed architecture and engineering to new limits, and which has had an enduring influence on late 20th century architecture and beyond. The design represents an extraordinary interpretation and response to the setting in Sydney Harbour. Today, the Sydney Opera House is one of the busiest performing arts centres in the world, each year staging up to 2500 performances and events, drawing around 1.5 million patrons, and attracting an estimated 4 million visitors. It comprises three groups of interlocking vaulted 'shells' set upon a vast terraced platform and surrounded by terrace areas that function as pedestrian concourses.
Spanning the city center to the North Shore, the Sydney Harbour Bridge is a wide steel arch bridge known for its beauty as well as function, providing a crossing for cars, trains, bikes and pedestrians. While the more daring can do the BridgeClimb to the top of the structure, opened to traffic in 1932, anyone can enjoy a walk for free. The walk over to the bridge museum in the tower, the history of the bridges construction and a super place to take some stunning photos of Sydney are well worth it. You can take some great pictures of the Sydney Opera House, the Rock area and the Sydney Harbour.
This area has so many little alley ways and niches that it would take a long time to mention them. Take the time to get there in the morning and just meander throughout a part of Australia's history that is very unique. There are special little cafe's and tea rooms along with pubs etc. Australia's oldest pub is worth a visit. Take your time to read the plaques and stories. The rocks is only a short walk from circular quay and on weekends there are markets. Take the time to go through the antique pavilion.
