Santorini Islands are located in the Aegean Sea about 200KM (120 miles) from the Greek mainland. They are the remnants of an old Volcanic island that exploded with such force about 3,600 years that the fall out probably caused the collapse of the Minoan civilization on the nearby island of Crete. Santorini is a crescent shaped archipelago of islands surrounding a central caldera. The largest island of
Thira, next Therasia and the smallest Aspronisi. These surrounds a huge central lagoon about 12 x 7 km across with a small volcanic island, Nea Kameni, in the middle which has been dormant since 1950. The natural harbour of the caldera has high steep cliffs that rise out of the sea to create a natural defense for the island and a safe haven for shipping. High above the sea on the cliff tops are some of the most picturesque villages in Greece & Europe.
