The windmills of Mykonos are the trademark of the whole island. They can be seen from every point of Chora village and they are the first thing to see when the ship gets close to the harbour, as they stand on a hill overlooking the area.
There are 16 windmills today on Mykonos. Most of them were built by the Venetians in the 16th century and till the early 20th century, they were used to grind the wheat. They were an important source of income for the inhabitants and supported a lot the economy of Mykonos in difficult times. With the evolution of economy, their use gradually declined till they stop working in the middle of the 20th century.
Their architecture is similar. They all have round shape, white colour and a pointed roof. Such windmills are found in almost all Cyclades islands. One of these windmills has been transformed today into a museum. SOURCE: wikipedia
