40.966°N 24.528°WAcontisma or Akontisma (Greek, Ancient (to 1453);: Ἀχόντισμα), also called Hercontroma or Herkontroma, was a settlement in ancient Macedon[1] near the border of Thrace on the coast and on the Via Egnatia, 8 or 9 miles (13 to 15 km) eastward of Neapolis (modern Kavala), on a pass of the same name. Its site has been identified with remains about 2 miles (3 km) east of Nea Karvali.
An account describing the political consolidation of ancient Macedon identified Acontisma as an outpost located at the easternmost limit of the Macedonian territory.[2] During the Roman times, Acontisma was also the eastern boundary of the province of Macedonia. This settlement, which was some sources described as a mountain pass[3] and a border passage, was included in one of Trajan's inscription citing road repairs.[4]
