Kaliningrad is an important commercial and military seaport.

An excerpt from the article 24 facts about Kaliningrad

The port is located on the Vistula Lagoon on the Pregolya River and has been open to international shipping since 1991. It accepts seagoing vessels with a maximum draft of 8 m.

The port of Kaliningrad does not freeze during harsh winters, so it is available for navigation all year round. However, when low temperatures persist for a long time, ice appears in the channel connecting the port with the Baltic Sea. Then icebreakers come into action - the last use of icebreakers took place in 1997.
