Nashtifan is close to the border of Iran and Afghanistan. Here, 120 days out of a year are windy, which allows windmills to function well. Some scholars have proposed that these wooden windmills are the origin of the first windmills, which then spread to China in the east and Europe in the west. Pine wood, which grows in the neighborhood forest, is usually used as the axis of the windmill.
