occupies the top of a high hill (627 m. a.s.l.), in a strategic position,
controlling the valley of Nestos. The trapezoidal enceinte is built of marble
blocks. Excavations have revealed six towers, five gates and a beehive cistern,
12 m. deep. The fort was built by king Philip II in ca. 340 B.C., after the dissolution
of the powerful state of Odryssae. Because of its strategic location, it was used
by a series of dynasts over the centuries, such as Philip V, Perseas, the Romans,
the Thracians and emperor Justinian.
The first archaeological investigation on the site was undertaken
in 1973 by Diamantis Triantaphyllos, who has been conducting the excavations since
then. Work is carried out almost every year and as a result, the fortress has
been almost completely uncovered.
The most important monuments

It is 12 m. deep and has a maximum diameter
