Parnes is an extensive, 30 km long mountain range with a maximum width of 20 km. It is located in the northwestern section of Attica. Mount Parnes’ highly rugged relief features steep slopes, spectacular gorges, valleys, and plateaus. There are also several caves, the most famous being Lychnospelia in Phyle, at an altitude of 675 m, where the goatfooted god Pan and the Nymphs were worshipped. In antiquity, Parnes accommodated several fortresses, as it constituted the natural boundary between the territory of Athens and that of its northwestern neighbours. Moreover, a major shrine dedicated to the cult of Zeus, as well as many ancient towns and villages have been identified across Parnes.
