At the Byzantine castle of Makri
The ruins next to the post-Byzantine church of Agia Anastasia belong to the Byzantine fortification of Makri. The masonry dates the construction to the 10th century.
The perimeter of the double walls was clearly larger in its original form. Greater reinforcement was provided by peripheral towers, such as the circular one that survives in ruins in the north-east.
The little information we have from the excavations in the area and the ruined castle is supplemented by written evidence. From these it appears that Makri was a small but important town with a bishop and belonged to the diocese of Traianoupolis. At the beginning of the 13th century it came under the rule of the Franks, but very soon it was taken over by the Bulgarian Tsar Ivan I or Skylogiannis, who destroyed the castle. Its final destruction took place after 1361 when it was occupied by the Ottomans.
