About
About Dara (Anastasiopolis)
Justinian’s “impregnable” frontier megafort against Persia: a 3.5 km wall with 27 towers, an arch dam (earliest known) that doubled as reservoir and moat, and an underground cistern system 18 m deep carved under the agora. Procopius describes Anastasius founding Anastasiopolis 505 CE to counter Nisibis, and Justinian raising the towers to 20 m; the 530 CE Battle of Dara battlefield still scatters Sasanian mail outside north walls. The Roman village and dam still hold water after 1,500 years; the rock-cut cisterns function as gigantic moat filtrae.
Why it mattersOnly Roman city with surviving arch dam-reservoir integrated into fortifications; textbook Procopian fortress.
