The archeological site of Philippi is located in a plain between the mountain range of Orvilos in the north, Mt. Paggaion in the southwest and Mt. Symbolon in the east. This fertile plain was covered with swamps in antiquity that gradually dried up. The history of the site begins in 360 BC, when settlers from Thasos founded the city of Krenides, which received its name from the many springs in the area. The location of the city was strategic, as it controlled the narrow passage between the mountains and the swamps, leading from the port of Neapolis (Kavala) to the interior of Thrace. In addition, its inhabitants could take advantage of the agricultural opportunities afforded by the plain, the abundant timber of the mountains, and especially the rich gold and silver deposits of the area.
