The Netherlands may be flat, but there is still enough of an angle to make water flow, and good use has been made of that through the ages.
I proudly present three photos of the watermills in my region of The Netherlands.
The Oostendorper watermolen, near Haaksbergen:
Olympus Stylus 1s, 55mm, ISO400, f8, 1/80s
The watermolen van Singraven near Denekamp:
Olympus XZ-1, 80mm, ISO100, f5.6, 1/80s
The Noordmolen near Delden:
Olympus Stylus 1s, 75mm, ISO200, f5.6, 1/50s
There are a few more, and there is also a rather nice one near Alstätte called the "Haarmühle", but that one doesn't count, as it sits just across the border in Germany 8-).
Thanks for watching!
