Tasmania Richmond Bridge Originally named Bigge's Bridge, Richmond Bridge is Australia's oldest bridge still in use. It was built by convicts from sandstone quarried at Butchers Hill and hauled by hand carts to the bridge site.
Just at Eagle Hawk Neck about an hour from Hobart on the drive to Port Arthur, Tessellated Pavement, Tasmania, Australia. Some rocks are so perfectly cut you would think they were done by hand. Definitely all natural.
