Windmills of Oía

This guide to the Windmills of Oía in Santorini opens with the more than seventy grain mills once built across the island, of which barely a handful still stand. It examines the twin whitewashed towers known as Two Mill Oia, built from volcanic stone with a conical roof designed to shed the wind, and a vaulted interior found nowhere else in Greek windmill architecture. You'll hear about the sails, millstones and the surrounding compound of ovens, storerooms and a miller's house that once supported the grinding of wheat and barley. Stand at the western edge of Oia to take in both towers side by side.
