Akrotiri (Greek: Ακρωτήρι) is a village on the island of Santorini in Greece. It is located 15 kilometers south of the capital Fira, built on the slopes of a hill offering staggering views of the caldera cliffs. On top of this hill, there are remains of a Venetian castle (Goulas).
Akrotiri is part of the Thira region and had 489 permanent inhabitants according to the Greek census of 2011.
Southeast of Akrotiri and at a distance of approximately 2 km, the namesake Minoan Bronze Age settlement is located. This archaeological site is one of the most important of its kind in the Aegean.
West of Akrotiri and on Santorini's westmost tip, there is a lighthouse dating from 1892. Much of the town is built around the ruins of a 13th century fortress, the Castle of Akrotiri.
