Zelenogradsk (Russian: Зеленогра́дскⓘ; German: Cranz; Polish: Koronowo;[8] Lithuanian and Old Prussian: Krantas) is a town and the administrative center of Zelenogradsky District in Kaliningrad Oblast, Russia, located 34 kilometers (21 mi) north of Kaliningrad, on the Sambian coastline near the Curonian Spit on the Baltic Sea.

[11] In its heyday, Zelenogradsk (as Cranz) was a popular seaside resort on Germany's eastern Baltic coast, comparable to Bognor Regis in England.

During the 19th century, Cranz became the primary seaside resort for the Kingdom of Prussia on the East Prussian coastline, especially after the construction of a railway line connecting it with Königsberg (now Kaliningrad) in 1885.

The area was overrun by the Soviet Red Army during World War II and annexed to the Russian SFSR, although it suffered minimally through warfare.

The German population fled during the evacuation of East Prussia or was subsequently expelled in accordance with the Potsdam Agreement.
