Stephan Jantzen

The Stephan Jantzen is a 67.64-meter-long icebreaker built in 1967, now permanently moored in Rostock's city harbor where it serves as a museum ship showcasing maritime technology and icebreaking operations.

Constructed in 1967 at the Admiralitätswerft shipyard in Leningrad, this vessel served East German maritime authorities for over two decades, performing critical icebreaking missions in the Baltic Sea during the Cold War era.

Named after Warnemünde pilot master Stephan Jantzen who lived from 1827 to 1913, the ship represents the maritime heritage of the region and the historical importance of winter navigation in Baltic waters.

The museum ship welcomes visitors daily from 10:00 AM to 4:00 PM, operated by Technische Flotte Rostock e.V., though the vessel is not wheelchair accessible due to its historical design.

This icebreaker is one of the last preserved ships of the Nikitich class and Germany's second-largest icebreaker, offering rare insights into Cold War-era winter navigation technology and maritime engineering.
