Anafi is a small Greek island, it lies east of the island of Santorini and it has only 300 inhabitants. A peninsula at the eastern end of the island is dominated by a monolithic rock, Kalamos, among the largest in the Mediterranean at 584 m (1,916 ft). (Gibraltar is 426 metres (1,396 feet) high.) This tall monolithic rock, inaccessible by sea and hard to reach by land, forms a unique natural monument for the island. It plays host to rare species of flora and has impressive geo-morphological features. Its highest peak hosts the old Kalamiotissa Monastery. Its location and the view inspire an indescribable sense of awe in all visitors.
