Dubbed the original Sydney lookout, due to its position as the highest viewing point in Sydney when the bridge opened, the Sydney Harbour Bridge Pylon Lookout remains an interesting part of the bridge and Sydney history. There are 200 stairs to the Pylon Lookout, 87 metres above mean sea level, but on the way up there are three levels of exhibits where you will discover the history and construction of the Sydney Harbour Bridge, the men who built it, and the vision of JJC Bradfield, chief engineer. The Sydney Harbour Bridge is the world's largest (but not longest) steel arch bridge, and, in its beautiful harbour location, has become a renowned international symbol of Australia. The Pylon Lookout offers magnificent views of Sydney Harbour, Botanical Gardens and the surrounding areas. On a clear day you can see as far as the Blue Mountains.
