Upon the re-organisation of the Prussian lands after the Congress of Vienna, Fischhausen became the administrative seat of a district (Kreis Fischhausen) within the Province of East Prussia in 1818. A station on the East Prussian Southern Railway line from Königsberg to Pillau with a branch-off to Palmnicken (Yantarny) on the Amber Coast was inaugurated in 1865. From 1871, the town formed part of the German Empire. According to the German 1939 census, the town's population was 3,879. During World War II, the Soviet Red Army advanced towards Fischhausen after the capture of Königsberg. The town was captured after a battle on April 21–24, 1945; during the fighting the medieval town was almost completely destroyed. After the war, the town was transferred to Soviet control and in 1946 it was given its present name (which literally means "by the sea" in Russian). It finally lost its status as a district seat and was incorporated into Zelenogradsky District in 1947. Part of the newly established Baltiysky District since 1996, it was demoted in status to that of an urban-type settlement in 2005. In 2008, its town status was restored. Administrative and municipal status Within the framework of administrative divisions, it is incorporated within Baltiysky District as the town of district significance of Primorsk. As a municipal division, the town of district significance of Primorsk is incorporated within Baltiysky Municipal District as Primorskoye Urban Settlement.
