In earlier times, the entry was used for thoroughfare of horses and wagons,
which could then exit at the back of the mill (conveniently,
because horses do not move in reverse! ).
On the ground floor a souvenirs shop and residential area has been established.
If you take the first stair up you will be passing the living floor,
that's why the first stair is so long.
The thickness of the walls just under the ground is approximately 90cm.
These thicken even further in a curvature position as the depth of the wall increases, on account of the fact that there is no fondement and also to absorb the vibration caused by the milling.
