These windmills are in danger of disappearing
These windmills are a 1,000-years-old and can be found in the village of Nashtifan in northeastern Iran. Although they were recognized as a national heritage site by Iran, their elderly keeper, Mohammad Etebari, has been maintaining them for years. Still, he fears no one will take over the job of protecting them after his death.
The mills are made of clay, straw, and wood, and their vertical axis resembles those invented by the Persians around 500 CE. Each of these has eight chambers, and each chamber has six blades. Hopefully, they will continue to stand for 1,000 more years. Losing them would be a true shame.
