Dusseldorf (U-boat escape tower)

The Düsseldorf (U-boat escape tower) is a historic, reinforced structure built to assist submarine crews in escaping during emergencies. Located at the U-boat pens in Germany, it served as a refuge where crew members could safely evacuate from submerged submarines through specialized escape trunks and chambers. The tower provided a safe passage to the surface, especially during World War II when U-boat accidents posed significant dangers. Today, it stands as a preserved military relic and example of advanced submarine rescue technology from that era.
