Slavsk

Slavsk is a town in Kaliningrad Oblast, Russia, located on the Deima River, near the Curonian Lagoon.

Historically, Slavsk was known as Heinrichswalde when it was part of the German province of East Prussia. Founded in 1292 by the Teutonic Order, Heinrichswalde was granted town privileges in 1725. The town's economy was largely based on agriculture, forestry, and peat extraction.

Following the end of World War II in 1945, the northern part of East Prussia was annexed by the Soviet Union. Heinrichswalde was renamed Slavsk in 1946 in honor of Ivan Dmitrievich Chernyakhovsky, a Soviet Army general, though the name also alludes to the Slavic population of the region following the war.

Today, Slavsk is an administrative center of the Slavsky District within Kaliningrad Oblast. The town's population is relatively small. Its economy is diversified but includes agriculture and small-scale industry. Remains of its East Prussian past, including some architecture, can still be seen. The area is characterized by its natural environment, including proximity to the Curonian Lagoon and its associated ecosystems.
