At Barossa’s Whispering Wall, your secrets aren’t secret anymore!

The story goes that the secret of Barossa’s Whispering Wall was whispered quite by accident quite near the end of its construction in 1902. The arch dam was constructed from 1899 to 1902 across the Yettie Creek Gorge near Williamstown, an hour northeast of Adelaide, and was hailed as a remarkable feat of engineering back in its day.
