Santorini is a small, circular group of volcanic islands located in southern Aegean Sea, about 200 km south-east from Greece's mainland. It is also known as Thera and is the southernmost member of the Cyclades group of islands in Greece. It is believed that the island was the site of one of the largest volcanic eruptions in recorded history when it erupted cataclysmically some 3,500 years ago, at the height of the Mycenaean epoch. The eruption left a large caldera surrounded by volcanic ash deposits hundreds of feet deep and, some people believe that its effects may have indirectly led to the collapse of the Minoan civilization on the island of Crete. Brace yourself for a spectacular visual that will take your breath away. Considered by many as the most beautiful of all the Greek Islands, what make Santorini so different from any other island are its imposing landscape and the caldera with its impressionistic contrast of colours. In fact the violence of the volcanic eruptions are visible everywhere-the black-sand beaches, raw lava-layered cliffs plunging into the sea and in the soil’s fertility supported by the coiled grape vines. It is believed the sunset over the island of Santorini is one of the best in the world.
