PLOT
The Serpent’s Walls are over a thousand kilometers of ancient fortifications. These earthen embankments surrounding the modern territory of Kyiv are shrouded in legends. Researchers still cannot agree on who built them and why. How were they planned so effectively to protect the approaches to Kyiv, taking into account rivers, lakes, swamps, and hills? Traditional science claims that they were built during the reign of Volodymyr the Great and Yaroslav the Wise. But there are daredevils who challenge the traditional view of history. What if the Serpent Walls are two or even three thousand years old? Maybe Kyiv is much older than is commonly believed?
