Thasian colonists established a settlement at Krenides (meaning "springs") in Thrace in 360/359 BC near the head of the Aegean Sea at the foot of Mt. Orbelos, now called Mt. Lekani, about 13 kilometers north-west of Kavalla, on the northern border of the marsh that, in antiquity, covered the entire plain separating it from the Pangaion Hills to the south.
