The Dodecanese is a complex of over 163 islands and islets, set in the Aegean Sea, of which only 26 are inhabited. The islands form part of Greece's eastern border with Turkey. The largest islands of the Dodecanese are: Rhodes, Kos, Astipalea, Kalymnos, Karpathos, Kassos, Kastelorizo, Leros, Nisyros, Patmos, Symi and Tilos.

In the summer the prevailing wind is the Meltemi that blows from the N � NW. It blows from June through to October and at its peak may reach a force 7. The spring and autumn sees winds from the SE, usually with strengths between 2 � 4. Summer temperatures can rise to 35 deg C. The winters are mild.

The Dodecanese have been inhabited since prehistoric times. They were ruled first by the Minoans and then the Achaeans. But their economic and intellectual development began with the arrival of the Dorians in 1100. Kos prospered in the 4th and the 3rd century BC because of the School of Medicine founded there by Hippocrates. The Romans occupied the islands in 146 BC to be followed by the long Byzantine period till the time of the Crusaders. In 1309 the Knights of the Order of Saint John became the rulers of Rhodes and then extended their sovereignty to the other islands as well. In 1522 the islands fell to the Turks and in 1912 by the Italians. The islands of Dodecanese were united with Greece in 1948.
