Primorsk (Russian: Примо́рск; German: Fischhausen; Polish: Rybaki;[7] Lithuanian: Žuvininkai/Skanavikas) is a town in Baltiysky District of Kaliningrad Oblast, Russia, located on the Vistula Lagoon.

It is situated by a bay on the northern shore of the Vistula Lagoon, about 30 km (19 mi) west of the administrative centre Kaliningrad.

The site has been associated with the name of St. Adalbert of Prague, who was sent with soldiers of Bolesław I the Brave of the newly established Poland to Christianize Prussia.

Upon the division of the conquered lands, the Bishop of Sambia had a castle erected at the site named Schonewik (derived from Old Prussian: Skanevīs).

On 12 February 1526, the Hohenzollern duke Albert, former Grand Master of the Teutonic Knights, married Princess Dorothea of Denmark at the Fischhausen Castle chapel.

[12] 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.
