120.000 square meters and an area constituted by three low ridges, originating near the slopes of Cithaerum and running north. It is surrounded by a huge enceinte including roughly 850.000 square meters. Inside, a fortification delineates the plateau, and a massive wall intersects the huge circumvallation in its southern part. The plateau, situated in the north western part of the huge area, shows some characteristics of an acropolis. It was surrounded by walls which, along its southern fringes, have been preserved in a rather fine state.
Scant traces prove that the rest of the plateau was also circumvented by a line of fortifications.
From its southwestern part there emerges another line of walls, leading south. Flanked by towers at irregular distances, it incorporates in its course a gateway, traces of which could be located by means of a geophysical survey conducted by the Fitch-Laboratory of the British School of Archaeology at Athens. Near the mountain slope the wall turns due east, only to change direction again, after a short stretch, towards northeast. From this point it runs more than a kilometer, interrupted by another, the eastern gateway. A good deal after crossing the modern asphalt road it passes the remains of an ancient bridge situated to its east.
