Riddoch Art Gallery Mount Gambier's Riddoch Art Gallery is constructed out of two materials. The local limestone is painted to protect it from the elements, whereas the dolomite is free to show its reddish hue.
Directly behind the gallery is the cave garden (actually a sinkhole), which in Aboriginal mythology is the home of a devil Mirka, who was chased their by son of a local god. The water than descends to its depths is supposedly the tears of Mount Gambier itself, (Thu-Ghee, in local Buandik language), as a mother mourning her son Woo, the one-legged, one-armed hunter.
