The Byzantine walls of Komotini
The castle of Komotini was built in the 4th century AD by the emperor Theodosius I (379-395AD). As Byzantine Koumoutzina was an important junction on the Roman Egnatia road and a passage from the Rodopi mountain range to the sea, a strong wall of about 10 meters high was built to protect the city. For its reinforcement the wall had 16 towers, 12 rectangular and 4 circular towers at its corners. After the Ottoman occupation of the city in 1362, the wall was used as building material and much of it was destroyed. Equally great destruction took place during the Bulgarian occupation at the beginning of the 20th century.
