Whispering Wall, Adelaide
One of the highest dam in Australia, the retaining dam of the Barossa Reservoir, is better known as the "Whispering Wall".
The water comes from through a tunnel more than two kilometres through the range from a weir on the South Para River.
The tall thin concrete dam curved against the pressure of the water was radical at the time of construction over a 100 years ago and the parabola effect casuse soundwave bounces so ppl speaking at one end of the dam can be heard as if the person is standing beside you ! The wall is one sector of a perfect circle, and the soundwaves bounce in a series of straight jumps along it to the other end. Hence the nick Whispering Wall
The Whispering Wall - give it a go and be astounded.
To get there - head towards the Barossa Reservoir Via Yettie Road, Williamstown
