Dave and I went for a walk around Gröbendorf from Mauterndorf, and from a grey start it turned into one of those glorious blue sky days.
I drove Dave nuts with the camera.
So my original theory was that the ruin was an Smithy and a forge that was waterpowered, as I’d seen ponds in farmhouse garden further up the road.
When we we looked, we could see they were steam fed and had never been diverted form the Turrach, so were never storage ponds for the forge. One theory gone!
Then we walked onto the next village , Pichl, where I thought there was an oven for smelting.
Wrong, it was a Knights Castle and was ever only a castle.
It was surrounded by the farm of what must be a very wealthy farming family. This must be the poshest private chapel in Lungau!
So still no ideas of the origins of the ruin, but had a great walk! Time Team please come and sort out!!!!
