The Museum of the World Ocean is Russia's largest maritime museum and a unique complex on the banks of the Pregolya River. It comprises 17 separate exhibition objects including the research vessel Vityaz, the Cold War submarine B-413, the space communications ship Cosmonaut Viktor Patsayev, and the floating lighthouse Irben. The main building houses aquariums, geological exhibitions, and shell collections. The museum offers a comprehensive journey through maritime navigation history and scientific ocean exploration. Tickets can be purchased individually for each object or as a combined 9-object pass. The submarine is accessible only through guided tours and features incredibly narrow passages for an authentic experience
