Akrotiri lighthouse, Maritime lighthouse in Akrotiri, Santorini, Greece.

Akrotiri Lighthouse is a squared stone structure on the southwestern cliffs of Santorini that combines a low tower with an attached keeper's dwelling. The building overlooks the Aegean Sea and serves active navigation purposes today.

The lighthouse was built in 1892 by a French trading company to guide ships through the strait. It initially operated with petroleum fuel and was later converted to electrical systems.

The lighthouse's name comes from the Akrotiri headland, near the archaeological site of the same name, 18 km from Fira. Its white tower with stone-coloured borders, green doors, windows and dome, and a weather vane, follows Cycladic architecture. The French company Collas et Michel built it in 1892.

The location sits away from the main village and requires private transport or a car to reach. The best time to visit is early morning or late afternoon to avoid intense sun and crowds.

The lighthouse was built by the French firm Collas et Michel, and its lantern stands 100 m above the Aegean, flashing white every 10 seconds with a range of 17 nautical miles. Its international codes are Admiralty E 4266 and NGA 15952.
