Chernyshevskoye

Chernyshevskoye (Russian: Черныше́вское; German: Eydtkuhnen, from 1938: Eydtkau; Lithuanian: Eitkūnai; Polish: Ejtkuny) is a settlement in Nesterovsky District in the eastern part of Kaliningrad Oblast, Russia, close to the border with Lithuania.

The settlement was first mentioned in the 16th century, when the area was part of the Polish Duchy of Prussia, near where its eastern border ran as stipulated by the 1422 Treaty of Melno.

The railway connection decisively promoted Eydtkuhnen's development: the Neo-Romanesque Lutheran parish church was built according to plans by Friedrich Adler and consecrated in 1889; the settlement received town privileges in 1922, when the population reached 10,000.

After World War I and the Act of Independence, the border crossing led to Lithuania, while corridor trains provided the railway connection to Berlin.

With the implementation of the Oder-Neisse line after World War II, the area became part of the Soviet Union, while the remaining German population was expelled.
