Although most windmills in the Fens were used to pump water in the drainage dykes, the Denver windmill was a traditional grian-grinding mill so actually unconnected with the nearby Denver Sluice. It sits on the western edge of the village on the way out to the sluices.
The windmill is open all year, generally from 10 til 5 in the summer (to 4 in the winter (from12 Sundays; to 4 between November and March).
It was first built in 1835 and stopped working when struck by lightning in 1941, but it has now been fully restored.
The windmill also contains various other workshops, including a leather workshop.
They even have accommodation available!
