The "chora" of Astypalea is built on a hill and the traditional settlement bears strongly characteristics of the Cycladic civilization. In the neck of the hill the eight conserved windmills form the dividing line between the historic and the modern settlement and on the top of the hill stands the venetian castle. On the island are scattered, throughout its extent, archaeological discoveries that cover a variety of prehistoric / Mycenaean until the Middle Ages.
