Serpent's Wall

Serpent's Wall is an ancient system of earthen earthworks located in the middle Dnieper Ukraine that stretch across primarily Kiev Oblast, 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.According to a legend, the earthworks are results of ancient events when a mythical hero Kozmodemian in order to slay gargantuan Dragon harnessed it in a giant plow and furrowed.
