from the message

Serpent's Wall (Zmiievi valy) is an ancient system of earthen earthworks (valla) located in the middle Dnieper Ukraine (Naddniprianshchyna) that stretch across primarily Kyiv region, Ukraine. They seem to be similar in purpose and character to Trajan's Wall situated to the southwest in Bessarabia. The remaining ancient walls have a total length of 1,000 km and constitute less than 20% of the original wall system. The term "Serpent's Wall" built in the 11th-12th centuries.

The ancient walls were built between the 2nd century BC and 7th century AD, according to carbon dating. There are three theories as to what peoples built the walls: either the Sarmatians against the Scythians, or the Goths of Oium against the Huns, or the Early East Slavs against the nomads of the southern steppes. In Slavic culture, the warlike nomads are often associated with the winged dragon, hence the name.
