Macron Teichos
Μακρὸν τεῖχος
Macron Teichos (Μακρὸν τεῖχος), also called the wall of Anastasius,
was a fortification constructed in A.D. 507, by the emperor Anastasius I. of Constantinople, as a means of defence against the Bulgarians: it consisted of a strong wall running across the isthmus of Constantinople, from the coast of the Propontis to that of the Euxine, Some parts of this wall, which at a later period proved useful against the Turks, are still existing.
