The windmills are a defining feature of the Mykonian landscape. There are many dotted around the island, but most are concentrated in the main town of Chora. The famous "Kato Mili" in Chora (Greek for lower mills), stand in a row on a hill overlooking the sea to harness the strong northern winds. Capped with wood and straw, the windmills were built by the Venetians in the 16th century to mill flour and remained in use until the early 20th century. Many have been refurbished and restored to serve as homes to locals and vaults to numerous Mykonian heritage documents.
