The North-West Frontier of Attica
Of all the states in ancient Greece, Attica seems to have had the most interesting and complete system of land defences. A chain of important fortresses, of most of which there are still considerable remains, follows the line of the Kithairon–Parnes range: Eleutherai, Oinoe, Panakton, Phyle, Dekeleia, Aphidna and Rhamnous. It may appear at first that this series of strongholds was designed expressly to mark off Athenian territory, but whilst incidentally and in large measure they served this end, in origin they were intended rather to defend the various roads from Attica into Boeotia. A fresh examination of these forts and their relation to the Attic frontier may be of some service and interest.The natural boundary of Attica on the N.W. is the mountain ridge which begins on the Halkyonian sea-coast behind Aigosthena and continues almost due eastward to the Straits of Euboea, reaching the sea at Cape Kalamos. It is not surprising, therefore, to learn that the early tradition made the Megarid and Attica into a single kingdom. Plato, describing an idealised primitive Attica, gives as the boundaries the Isthmus and the heights of Kithairon and Parnes extending down to the sea, with Oropos on the right and the Asopos on the left.
