"The Waterloo Bridge across the Thames in London was constructed in 1817 to the design of Sir John Rennie [bio]. The granite bridge had nine arches each of 120' span and was 2,456' long including approaches. This bridge was replaced with a modern reinforced concrete bridge in 1942.
Stones such as these from the bridge were presented to Australia and other parts of the British world to become further historic relics in the British Commonwealth of Nations"
