Here's a sprinkling of the old, and the new, architecture around Sydney Harbour.
The Sydney Harbour Bridge, reported to be the heaviest and biggest steel arched bridge in the world, was opened in 1932. Further history can be found on the National Film and Sound Archive site here.
Can you believe there are actually guided bridge-climb opportunities on this bridge? It's all here and is a very popular business venture.
The end of this street in the historic Rocks area, is tall sandstone cliff-face. And just further along, on the corner, was this plaque.
