The Santorini windmills, most famously the white round mills of Oia, were 18th and 19th-century grain mills powered by the island’s strong meltemi wind, now restored as iconic photo landmarks and unusual places to stay. This guide covers what they are, the history, where to see them and tips for visiting.
The windmills are a beloved sight of the wider Santorini travel guide. They crown the villages. The sections below cover the windmills.
What are the Santorini windmills?
The Santorini windmills are whitewashed round stone mills with conical roofs, built to grind grain into flour using the island’s strong winds. The best-known pair stands at the northern tip of Oia, framing the village against the caldera.
The windmills are among Santorini’s most photographed landmarks. They are classic Cycladic mills, cylindrical whitewashed towers capped by a conical wooden roof that once carried cloth sails, built to harness the wind for grinding the island’s grain into flour. The best known stand at the northern edge of Oia, where two restored white mills crown the village against the blue caldera. They are not unique to Oia: a cluster survives at Emporio in the south, and single mills stand across the island. Picturesque and evocative, they recall an age before electricity when wind power fed the islanders, set within the wider Oia. Their history runs deep.
What is the history of the windmills?
Windmills worked on Santorini from the late medieval period, with surviving examples built between the 17th and 19th centuries. Around 60 to 70 mills once ground grain, powered by the meltemi wind and tied to village bakeries.
The windmills tell the story of the island’s farming past. Records suggest wind-powered mills existed on the island as far back as the 1300s, though none of those earliest structures survive, and the mills still standing date from the 17th to the 19th centuries. At their height around 60 to 70 windmills worked across the island, an essential part of the agricultural economy. They ground the local barley and wheat into flour, and often stood beside village bakeries. They ran on the meltemi, the strong northerly wind that blows almost year-round, giving free, reliable power. As industrial milling spread in the 20th century, the windmills gradually fell out of use, set out alongside the guide to Santorini history. They survive in a handful of spots.
Where can you see the windmills?
The most famous windmills stand at the northern tip of Oia, near the castle and the start of the sunset path. A well-preserved row lines a ridge at Emporio in the south, and single mills stand around the island.
The windmills are scattered but easy to find. The iconic pair sits at the far northern end of Oia, beyond the castle of Agios Nikolaos near where the sunset crowds gather, framing the village and caldera in the classic view. In the south, the large village of Emporio has a fine row of windmills lined up on a low ridge above the houses, less visited but very photogenic in the late light. Beyond these, single mills dot the island in villages and on hilltops. Owners have restored a handful and converted them into holiday rentals, so you can even stay inside a piece of the island’s history, set out alongside the guides to Emporio and the villages. Timing tips help.
What tips help for visiting?
The tips are to photograph the Oia windmills early morning or at golden hour to dodge the crowds, to pair the Emporio mills with the old quarter, and to consider a night in a converted windmill.
A little timing improves a windmill visit. The Oia mills sit right where the famous sunset crowds gather, so for clean photos and soft light, come early in the morning when the lanes are quiet, or at golden hour before the throng builds, rather than the packed minutes around sunset itself. The Emporio windmills are far quieter and pair well with a wander through that village’s atmospheric medieval kastro and maze of lanes. For something special, converted windmills are available to rent, offering a memorable night inside a round, thick-walled tower with a view. Wherever you go, the white mills against the blue make irresistible photographs, set out alongside the guides to the sunset and a Santorini photoshoot. The design behind them is worth knowing.
How were the windmills built and how did they work?
Each windmill is a thick-walled cylindrical tower of local stone, whitewashed against the sun and capped by a rotating conical roof. Cloth sails on wooden arms caught the meltemi and turned a shaft that drove two millstones inside.
The design is simple and effective. Builders raised a round tower from volcanic stone, plastered and whitewashed it, and topped it with a light conical roof of timber and reed. Wooden arms carried triangular cloth sails, and the miller reefed or spread the canvas to match the strength of the wind. The turning arms drove a vertical shaft, which spun the upper of two heavy millstones against a fixed lower stone. Grain poured from a hopper into the gap between the stones and left as flour at the rim, ready to bag. The round shape let the tower face the wind from any direction, and the thick stone walls kept the flour cool and dry inside. This robust build is why the towers still stand today.
What role do the windmills play today?
The windmills no longer grind grain and now serve as photo landmarks, restored holiday homes and symbols of Santorini. The Oia pair anchors the classic caldera view, while the Emporio row draws photographers away from the crowds.
The mills have found a second life in tourism. None grind grain now, yet they remain among the most recognisable sights on the island and appear on postcards, prints and travel covers. Owners have restored a handful of towers into boutique studios and holiday homes, keeping the round stone shell while fitting a bed, a small kitchen and a terrace inside.
The Oia mills mark the end of the sunset walk and the frame most visitors want in a photo, while the Emporio row rewards those who venture south. Preserving these towers keeps a working memory of the island’s pre-electric past alive, tying the windmills to the farming villages and bakeries they once fed, set out alongside the guide to the Santorini caldera. The questions below cover the points travellers ask most.
Frequently Asked Questions
What are the Santorini windmills?
The Santorini windmills are traditional whitewashed round stone mills with conical roofs, built to grind grain into flour using the island’s strong winds. The most famous stand at the northern tip of Oia, framing the village against the caldera, with others at Emporio and across the island.
Where are the windmills in Santorini?
The most famous windmills are at the northern tip of Oia, near the castle and the sunset path, with a fine cluster at Emporio in the south. Single windmills stand around the island, a handful now converted into holiday homes, so you can even stay inside a restored mill.
Why does Santorini have windmills?
Santorini has windmills because they ground the island’s grain into flour, harnessing the powerful meltemi wind that blows almost year-round. Around 60 to 70 mills once operated, mostly built between the 17th and 19th centuries and often tied to bakeries, before industrial milling made them obsolete.
Can you stay in a Santorini windmill?
You can stay in a Santorini windmill, as owners have restored a handful of the round stone towers into studios and holiday homes. These keep the thick walls and conical roof outside while fitting a bed, a small kitchen and a private terrace with a caldera or village view inside.
