Viersen.

The mill at Hamm ("Hammer Mühle") is one of the twelve mills mentioned as being located in Viersen in 1246.

This mill has been splendidly restored, so far as one can make out from the outside. It is located in a beautiful, tucked-away spot (spoiled only - and typically - by some very intrusive electricity pylons) in Hamm, one of the original 9 "Honschaften" (hundreds or neighborhoods technically comprising 100 homes) of the old lordship of Viersen.
