A modern wonder of art and architecture, Arno Grotjahn's wall contains almost every household item you can imagine and more. The walls reach two metres high and extend for at least 70 metres. They are constructed of concrete and rock brought from Arno's opal mine at Opalton and studded with rusted lawnmower parts, boat propellers, vintage typewriters and sewing machines and even a couple of complete motorbikes. Every part of the Wall has a story, and if you are lucky, you may run into one of the locals happy to share them.
