Как называлась первая оборонная стена Константинополя?
Several fortifications were built at various periods in the vicinity of Constantinople, forming part of its defensive system. The first and greatest of these is the 56 km long Anastasian Wall (Gk. , "teichos Anastasiakon") or Long Wall (, "makron teichos", or , "megalē Souda"), built in the mid-5th century as an outer defence to Constantinople, some 65 km westwards of the city. It was 3.30 m thick and over 5 m high, but its effectiveness was apparently limited, and it was abandoned at some time in the 7th century for want of resources to maintain and men to garrison it. For centuries thereafter, its materials were used in local buildings, but several parts, especially in the remoter central and northern sections, are still extant.
