Amphipolis was an ancient town built in eastern Macedonia, on the shore of the Strymon River, in the position of a town that used to be called the “Nine Streets”.
Amphipolis was established by the Athenians in the year 437 B.C. in order to control the rich area in raw materials and was finally abandoned in the 8th century AD.
