Massive Wooden Screws

We've just come back from a week in Italy. On a particularly hot day we sought some relief in a very nice air conditioned museum on the making of olive oil. This massive wooden screw was at least 6" diameter, I wonder what that wood look like in a work bench!
This was used for the pressing of olive pulp to extract the oil.

There were wooden screw everywhere. They had an old press still working powered by water which was fascinating to watch.

We stayed in Bardolino on the shores of Lake Garda and had a very relaxing time. I can highly recommend this area, the scenery is stunning, the food and wine were lovely and it wasn't too touristy or expensive to eat out. The weather averaged 30 degrees and we didn't see a drop of rain.
Seems like a distant memory............
