Sydney sandstone

It was time to walk back home. On the way we passed the Town Hall and Queen Victoria Building. Sandstone is characteristic of Sydney's grand old buildings.

From Wikipedia: The main public buildings in Sydney, completed from the 1850s until the 1900s were built in sandstone from Pyrmont where some 50 quarries operated. The best stone was 'Paradise', a soft rock that is easy to carve, and when weathered colours to a warm, golden straw colour. It is pale grey when quarried but contains the mineral siderite, an iron oxide, that virtually rusts and gives the stone the yellow colour.
