Meet your guide, a licensed archaeologist, at the entrance of Akrotiri Prehistoric City. Get assistance in buying the entry ticket and embark together with a group on a guided tour through Akrotiri Prehistoric City.  In the 16th century BC, a volcanic eruption destroyed all life on the island. Most of it collapsed beneath the waves and remained undiscovered until the excavations began in 1967, led by Professor Spyros Marintos. He uncovered the evidence of a city with houses, streets, squares and workshops, all of which had been covered under a thick blanket of pumice for almost 3,500 years.  Marvel at the well-preserved buildings and passageway in the excavated area. See the beautiful pottery, the roads, and squares of a city 3,500 years old. Explore the two and three-story houses, which were once decorated with wall paintings and get an insight into the ancient civilization of Santorini.  After the guided tour you are free to walk around the site at your own pace.
