A cross-wall on the hill Palia Pyli (modern translation of the old name Eski Kapi) east of Kavala and west of the village Chalkero overlooking the National Road (Egnatia road).
The monument is registered as “Cross-Wall of Akontisma” because it is relatively close (actually 7km) to the old town Akontisma which was also a station on the ancient Egnatia road. Akontisma was known as the last city of Macedonia to the east.

Structure, Fortification & Buildings

This is a long, straight fortification consisting of two parallel walls 0.75 to 0.80cm thick protecting an inner corridor 1.0 to 1.5m wide.
Its length is about 250m and its preserved height from 0.5m to 3.5m.

At the northern edge, there are the remains of a rectangular tower. A similar tower must have existed at the other end, at the south. However there is no trace of a southern wall neither traces of a gate, which reasonably should be somewhere in the middle.

The date of construction is unknown. A possible chronology would be the 4th or the 5th century AD when invasions from barbarian tribes had become a big problem for the eastern empire.

To the west of the wall, at 80m, there is a strong tower which is from the Ottoman period.
