Historic windmills are structures that harness wind energy to perform various tasks, such as grinding grain or pumping water. They have been used for centuries, with some of the earliest examples found in Persia around the 9th century. These windmills typically feature large blades that catch the wind, turning a central shaft connected to machinery inside. In Europe, particularly in the Netherlands, windmills became iconic symbols of agricultural innovation. Many of these mills were built in the 16th and 17th centuries and played a crucial role in managing water levels and processing crops. Today, many historic windmills are preserved as cultural landmarks and tourist attractions.
