It's time for a windmill page. Holland and windmills simply go together. There are
about 600 windmills remaining in Holland, many of them in good working condition.
The tops rotate on some, and with others the whole structure can rotate to face the wind.
The lattice blades have sails than can be trimmed. Some have elaborate air foils on the
blade edges for finer control.
The windmills were used for pumping water out of the polders and into the canals, or for
milling grains. There is one in a museum Arnhem, still working, that washes clothes!
It's a very big wash tub!
The inner workings of windmills, the gears and mechanical works, are mainly constructed
from wood, which is really marvellous craftsmanship. If you have a chance to visit the
inside of of working windmill, do take a look. Wonderful technology from the
pre-industrial era.
