Whispering Wall (Barossa Reservoir)
Whispering Wall
A curved dam completed in 1902. Its wall curve carries a whisper 140 metres to the far end, making it a fun stop on the road to the Barossa Valley.
When it was completed, the Barossa Reservoir dam was one of the largest concrete arch dams in the world. Its curved wall creates a parabolic acoustic effect. Stand at each end, speak softly to the wall, and the person at the other end can hear you clearly. A walk of a few minutes along the top of the dam also offers reservoir views. It is near Williamstown, on the way from Adelaide to the Barossa Valley, and the stop is free.
