Sawmill "De Gekroonde Poelenburg" (The Crowned Poelenburg) at the Zaanse Schans (Zaanstad - Holland)
This sawmill is known as a paltrok windmill: there were once 200 such windmills in the Zaan region. Paltrok mills have an open working floor on three sides and often have a dark, tar-covered body. When it needs to be turned to face the wind, the entire mill turns around on a ring of wooden rollers. This is why the paltrok rests on a base, unlike other types of windmill, in which only the cap turns around along with the sails. De Gekroonde Poelenburg was built in 1869 in Koog aan de Zaan. It replaced a windmill of a similar type, moved to make way for the Amsterdam-Alkmaar railway line. In 1904 the mill was forced to move again. This time to a place on De Gouw, a body of water in Zaandam. Finally, in 1963, it was again dismantled and reconstructed at Zaanse Schans. As seen in the photo above, the sawmill is currently under maintenance and missing it's wings.
