The Tourlitis Lighthouse is one of the most photographed sights in the Cyclades — a small automated lighthouse perched on a solitary sea rock just off the coast of Andros town. You can see it clearly from the castle promontory and from the terrace of the Museum of Modern Art, particularly striking at sunset when the light comes on.
The lighthouse is not accessible to visitors (the only approach is by boat and climbing), but its isolated position on the bare rock, with waves breaking around the base, makes it a compelling subject from a distance. It appears on countless postcards of the island.
