Karpathos is the second largest island in the Dodekanese after Rhodes. It is situated between Crete and Rhodes, in the “Karpathian Sea. The location of the island is strategic since it is the natural bridge which unites Crete with Asia Minor.

In aspect of geomorphology, Karpathos and Saria - the small island north of Karpathos - are two of the most gifted Greek islands. Calcareous rock beds define its morphological character. Over the rock beds of limestones lie more recent beds of stones such as plaster and others.
