Verzhbolovo Railway Station in Kybartai at about 1900
When in 1861 a branch of Saint Petersburg – Warsaw Railway was built from Vilnius to the Prussian border, where it was linked to Prussian Eastern Railway, the Russian border station near the village of Kybartai was named after the neighbouring town of Verzhbolovo (Вержболово), Lithuanian Virbalis, German Wirballen. Meanwhile, Kybartai has become a town bigger than Virbalis and the now Lithuanian border station is called Kybartai, too. The German station of the Prussian Eastern Railway on the western side of the frontier was Eydtkuhnen, today it is the Russian border station and called Chernyshevskoye (Чернышевское).
On June 30, 1941, an Einsatzgruppen of Germans and a few Lithuanian policemen perpetrated a mass execution of the local Jewish population. 106–116 men were murdered in a sand quarry.
From July to Automne 1941, other Jews from the town were assassinated with hundreds of victims from the nearby town of Virbalis on another execution site.
