The region in which Antigonea is to be sought is one of the most spectular in Europe. Its modern capital, Argyrokastro, is built on the steep and bare limestone mountainside to the west of the river Drin, which runs northwards through a narrow alluvial plain, enclosed on either side by roughly parallel ranges of great height. At this latitude the mountains of the Kurvelesh on the west, attaining heights over 5,000 feet, and the mountains of Llunxherië on the east, surpassing 6,000 feet, are relatively far apart; but as one proceeds northwards, the mountains converge and pinch the valley of the Drin between their towering masses. Here the Drin runs deep in a gorge, cut by its own waters in a shaley flysch formation, which is rich in springs, thickly wooded and deeply fissured. The modern road, which stays on the west side of the river, descends quite steeply through the gorge of the Drin. Below Lekel one enters an open flattish area, some 500 feet above sea-level, in which the Drin and the Bencë, emerging from an impassable limestone gorge, join the great river, the ancient Aous. The central point of the open area is Tepelenë, built beside the river. Below Tepelenë the Aous valley is relatively open, and the going is easy on foot, but the modern road climbs westwards and crosses the limestone mountain-sides on its way to the Bay of Valona. Above Tepelenë, or rather above Dragot, the Aous comes through a magnificent gorge, cut aeons ago by a much greater river. The floor is fairly level and bare of trees, and the river is confined in its conglomerate bed. The steep faces of the limestone mountains tower above one on either side, until one emerges from the gorge—the Aoi Stena—at Kelcyrë, where the countryside is open, undulating and wooded.
