Easton's 1897 Bible Dictionary:

Philippi
   (1.) Formerly Crenides, "the fountain," the capital of the
   province of Macedonia. It stood near the head of the Sea, about
   8 miles north-west of Kavalla. It is now a ruined village,
   called Philibedjik. Philip of Macedonia fortified the old
   Thracian town of Crenides, and called it after his own name
   Philippi (B.C. 359-336). In the time of the Emperor Augustus
   this city became a Roman colony, i.e., a military settlement of
   Roman soldiers, there planted for the purpose of controlling the
   district recently conquered. It was a "miniature Rome," under
   the municipal law of Rome, and governed by military officers,
   called duumviri, who were appointed directly from Rome. Having
   been providentially guided thither, here Paul and his companion
   Silas preached the gospel and formed the first church in Europe.
   (See LYDIA.) This success stirred up the enmity of the
   people, and they were "shamefully entreated" (Acts 16:9-40; 1
   Thess. 2:2). Paul and Silas at length left this city and
   proceeded to Amphipolis (q.v.).

     (2.) When Philip the tetrarch, the son of Herod, succeeded to
   the government of the northern portion of his kingdom, he
   enlarged the city of Paneas, and called it Caesarea, in honour
   of the emperor. But in order to distinguish it from the Caesarea
   on the sea coast, he added to it subsequently his own name, and
   called it Caesarea-Philippi (q.v.).
