Poppet Heads
The first is a small one NNE of the fire station at about 1-2o’clock? Can you see it?
The other is a much larger one like the replica they have at sovereign hill to the very east of the circle.
Photos from panorama at gold museum of Ballarat East in 1872.
Maybe if you go into the ballarat library and have a look at some old maps you might be able to relate them to this panorama…
