Greek islands
Dodecanese Islands:The Dodecanese (twelve islands) located at the south east Aegean Sea. Because of their strategic position, the Dodecanese  islands have been invaded  and occupied throw the years from various invaders Crusaders, Ottomans, the Knights of St John, Italians and Germans during the second world war.

The Cyclades islands are the most picturesque islands of Greece ,with white buildings and bright-blue church domes, while golden beaches meet the Greek aquamarine sea. Some of the Cyclades, such as Mykonos island, Santorini island, Paros island ,Delos, Amorgos island ,and Ios island, have vigorously embraced the tourist industry; others, such as Andros island, Kea, Serifos island and Sikinos island, are visited partly by foreigners but are favorites with holiday makers to Greece. The diverse outlines of the Greek islands as they protrude from the blue waters of the Aegean, bathed in the dazzling sunlight and embellished with little white houses, resemble, in the words of the Nobel Prize-winning poet Odysseas Elytis, “stone horses with rampant manes”. Above all, the people who live here, with their own individual approach to the world, bring to life the narrow alleyways of the villages and the pathways of the countryside, the countless tiny chapels, the white windmills, the dovecotes or the wind-bitten hillsides and are themselves a basic feature of the charm which this possess. The Greek island of Mykonos, between Siros and Tinos, is the most expensive and heavily visited of all Greek islands. It has the most sophisticated night life tann the nightlife of Santorini and is the gay capital of Greece . The town is an labyrinth of chic boutiques and small white houses with brightly painted balconies decorated with boukavilias and clemataries Santorini with its capital Fira (also known as Thira) is regarded by many as the most spectacular of the Greek islands . Thousands of tourists come every year to gape at the sea-filled caldera, a vestige of what was probably the world’s largest volcanic eruption, ever. Despite the crowds who visit in the summer, Santorini’s weirdness is its black-sand beaches and mighty cliffs. If you want to escape the tourist crowd, Sikinos, Anafi and the small greek islands to the east of Naxos offers an alternative.

It’s still possible to find some peace by visiting the undeveloped west coast, the mountainous interior and the villages of the Lassithi province , Crete was the center of the Minoan civilization, the first advanced civilization of Europe, which flourished from 2800 to 1450 BC.
