where is the whispering wall in south australia
Barossa Reservoir Barossa Reservoir is a reservoir in the Australian state of South Australia, built between 1899 and 1902 to supply water to Gawler and other northern country areas. Built at a cost of almost £170,000 the reservoir was hailed on completion as an engineering marvel, and at a total of 36 metres, was the highest in Australia.[2] The thin arch of the dam retaining wall, curved against the pressure of the water, was an innovation considered radical, and attracted the Reservoir international attention.[3] It was featured in the Scientific American and caused the American Engineers News to remark that its "boldness of design deserves to rank with the most famous dams in the world".[3] Nowadays, the dam is notable for its parabola effect, where a voice can be heard clearly from one side to the other — over 140 metres, end to end. This unusual acoustic phenomenon is a popular tourist attraction, and has earned the dam the title "Whispering Wall" (see Whispering gallery).[4]
