The earliest historical mention of Vyshhorod (the name translates as "the town upstream") dates from as early as 946 when it was described as the favourite residence of Saint Olga.Also mentioned in De Administrando Imperio, Vyshhorod served as the fortified castle and residence of the monarchs of Kievan Rus' on the Dnieper from that time until 1240, when the Mongols sacked it.Before the Mongol invasion, the church housed the relics of the first East Slavic saints, Boris and Gleb, but their subsequent fate remains a mystery.There is also a non-electrified terminus rail connection to Kyiv used for both freight transport and peak hour commuter passenger service.Jitney buses run between Vyshhorod and the Heroiv Dnipra station of the Kyiv Metro's Obolonsko–Teremkivska line.
