On a strategic location above the present-day settlement Glyfada or Glyfa (just opposite the islet Trizonia), on a hill called Palaeokastron, is located an ancient fortification dated to the end of the 4th or the beginning of the 3d century B.C. It is the acropolis of a so far unidentified city of Western Locris.
The impressive fortification made of local grey stone consists of two precincts, whereas in some remote and inaccessible parts of the hill the rocks offer natural fortification. The outer precinct comprises a surface measuring 170 x 300 meters and its construction is quite impressive, although in some parts somewhat coarse. On the north side are preserved the foundations of large rectangular walls. Between the two precincts on natural terraces there are remains of buildings, some of which must have belonged to edifices with a public or religious character. The interior fortification, which surrounds a surface measuring 100 x 55 meters is of a polygonal plan. The building system of the wall is mainly the pseudo-isodomic masonry with trapezoidal stones, whereas in some parts is polygonal. The masonry is preserved in quite good condition. It is fortified by eight semicircular towers, of which the two eastern ones protected the gate which constituted the main entrance to the acropolis.
Within the acropolis stands out a quite large cistern. Outside of the fortification and especially above modern Glyfa is located the ancient city, erected on the natural terraces. To the NE of the hill have been located traces of a house of the Hellenistic period. in the region connecting Palaeokastro with the modern national road between Naupaktos and Itea has been located the necropolis, of which remains of tombs are still extant. Finally, a distinctive cult of the region was that of the goddess Vassileia, as recorded on an inscription located in Glyfada, which is attested also in other cities of ancient Western Locris, such as Tolofon (Agioi Pantes) and Physcus (Malandrino).
