Until 1974, the site known to archaeologists as Servia, and discovered by A. J. B. Wace in 1909, about 6 km. north of the town of the same name, was to be found on the right bank of the Haliakmon, immediately downstream from the bridge carrying the main road from Larissa to Kozani (Plate 26a). The bridge shown in the frontispiece to ‘Prehistoric Macedonia’ was blown up by the retreating British Army in the last war; the Bailey bridge which replaced it and the site itself now lie over 30 m. below the surface of a great artificial lake, Limni Polyphytou, which fills the valley of the Middle Haliakmon, Plate 26b. The new bridge is the largest in Greece, and its impressive length emphasizes the importance of the crossing. Over it passes the highway, once the only practicable route connecting Thessaly, and ultimately central Greece, with Macedonia, while the bridges, past and present, marked the only convenient fording-place.
