We built this City from Rock and StoneWe built this city from rock and stone - sandstone in particular, especially after the gold rushes of the 1850s. This growing collection of Sydney pictures feature some of our many beaches, including Bondi Beach and Manly Beach.The Sydney region has been under the ocean many times throughout the eons, leaving a legacy of sandstone layers of beaches past, over millions of years. These sandstone layers can be found from our beaches to the Blue Mountains and form the headlands, adding to their beauty.
