Visit the city of Ancient Filippoi
Philippi was established by the king of Macedon, Philip II, on the site of the Thasian colony of Krinides or Crenides, near the head of the Aegean Sea at the foot of Mt. Orbelos about 8 miles 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 of Greece.
