Windmill - NOT amateur radio

We live right next door to this 200 year old windmill that has recently been fully restored. This photo was taken just after the rain. It has 4 sails although you cannot tell in this view.

At the moment, the sails are facing in the direction of our bungalow, although they change direction quite often with the wind. The sails have flaps that can be closed or open. The sails usually go around (flaps closed) on Thursdays and Sundays when the museum is open.
