In the 1960s, in the village of Moraczewo and Lednogóra, three post windmills were placed. They were moved from Swadzim, Sołeczna and Sędziwojew as part of the development of the Piast Route. All were created at the beginning of the 19th century. Despite of the late date of construction, I placed them on the site because post windmills in Polish lands appeared in the fourteenth century and without major structural changes, survived until the second half of the twentieth century.
Post mills are made of wood and covered with shingle from the outside. They had three floors. The bottom was occupied by the stabilizing construction, supporting the pole constituting the vertical axis around which the entire windmill structure was rotated along with the mechanism so that its propellers, also called wings, could be positioned in relation to the wind driving them. The two upper floors were intended for the production of flour. In the middle there were millstones. Shingle walls initially, due to the cost and weight, did not reach to the ground itself. Probably this view gave birth to fairy tales about “a witch hut”. In the stories, perhaps it was about discouraging children from approaching the windmill, because its wings were the cause of many fatal accidents. The post mill was able to grind from 60 to 90 tons of grain within 120-150 windy days of the year.
