These use of windmills on Crete dates to the 15th Century. The were introduced by Venetian engineers. Locally-constructed windmills appeared at the end of the 1800s.
During the 1950s, about 4,000 windmills powered of crops. Most of the windmills have been abandoned in favor of more efficient electric pumps.
I took the photo in 2004,when Jack & I toured Crete.
