Świnoujście is a city located in the Western Pomerania region of Poland. It serves as a seaport situated on the Baltic Sea and the Szczecin Lagoon in the country's extreme north-west.
The city is primarily situated on the islands of Usedom, Wolin, and Karsibór. The island of Karsibór was formerly part of Usedom but is now separated by the Piast Canal, which was constructed to facilitate ship access to Szczecin.
