The windmills at Kinderdijk in the village of Kinderdijk, Netherlands is a UNESCO World Heritage Site.

The use of windmills became widespread across the Middle East and Central Asia, and later spread to China and India. [22] Vertical windmills were later used extensively in Northwestern Europe to grind flour beginning in the 1180s, and many examples still exist. [23] By 500 AD, windmills were used to pump seawater for salt-making in China and ...

Dutch paltrok mills are, like post ...
