The temple of Athena Sunias, of which ruins are still extant, stood on Cape SUNION (Cape Colonna). On the eastern coast we find MARATHON, which is remarkable only on account of the battle-field in its neighbourhood. Its plain is not as level nor as fruitful as that of Eleusis; its surface is only not quite so rocky as in other parts of Attica, and covered with small hills. Among these hills, which are still visible, many are no doubt artificial, and are the tumuli under which the Persians and their attendants were buried. Sometimes arms and slings are still found there, some of which must have belonged to the barbarians and others to the Greeks. The interior of Attica contained several large places. The most important among them was ACHARNAE, whose population in the Peloponnesian war, as described by Thucydides, is almost incredible. If his statement is correct, the place must have had a considerable territory. Its inhabitants were charcoal-burners, and carried on other similar occupations. At a distance of seventy stadia from Athens there may still be seen on a hill the walls of the fort of PHYLE, which are almost uninjured. It was not a town, but only a hill surrounded with a wall (τεῖχος) within which in time of war the inhabitants of the surrounding country sought shelter for themselves and their property. It was taken by Thrasybulus. A second important frontier fortress was OENOE, and a third PANACTON, all of which were built especially against the inroads of the Boeotians. DECELEA, within sight of Athens, and situated on a hill, was an ancient and fortified place, of which, during the Peloponnesian war, the Spartans, on the advice of Alcibiades, took possession. They fortified it, for the purpose of having a safe place, from which they might lay waste the country around.
