The Zaan Windmill Society was founded in 1925 to preserve the last remaining windmills in the Zaan region, an area which once had more than 1000 windmills dotting the landscape. Their first successful restoration was De Zoeker oil mill. To date, they have now restored a total of 12 windmills in the Zaan area, many of which are open to the public. They society also runs a lovely little museum (de Molenmuseum) that tells more about the rise and fall of the Zaan windmills and their contribution to the Netherlands’ industrial history. The museum is located near the Zaanse Schans.
