Neris"For 276 km (171 mi) the river runs through Belarus, where it is called Viliya, and 235 km (146 mi) runs through Lithuania, where it is called Neris. The Neris connects two old Lithuanian capitals – Kernavė and Vilnius. Along its banks are burial places of the pagan Lithuanians. At 25 km (16 mi) from Vilnius are the old burial mounds of Karmazinai, with many mythological stones and a sacred oak." - (en.wikipedia.org 01.02.2020) Eastern Europe
