Stephan Jantzen

The Stephan Jantzen is a 67.64-meter-long icebreaker built in 1967 and now permanently moored in Rostock's city harbor. As a museum ship, it displays equipment and facilities that reveal how these vessels operated to keep Baltic waters navigable during winter.

Built in 1967 at a Leningrad shipyard, this vessel served East German maritime authorities for decades and performed critical icebreaking missions in the Baltic. It helped maintain shipping routes during harsh winter conditions.

The ship bears the name of a pilot master from Warnemünde and reflects the maritime traditions of this port city. Visitors can observe how crucial winter navigation in the Baltic was to the region's life and economy.

The vessel can be explored both outside and inside, but accessing certain areas requires climbing steep stairs and navigating narrow passages. Wear sturdy shoes, as decks and walkways tend to be slippery, especially in damp weather.

This vessel is one of the last surviving examples of a Soviet-designed icebreaker class and demonstrates engineering from an era when breaking ice required immense power rather than computer-guided precision. Few such ships remain accessible for visitors to board and explore.
