The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site. A windmill is a structure that converts wind power into rotational energy using vanes called sails or blades, by tradition specifically to mill grain (), but in some parts of the English-speaking world, the term has also been extended to encompass windpumps, wind turbines, and other applications.
