A protected site, not a dive attraction
Calling a wreck an official war grave changes how it is treated: it is regarded as a place connected to wartime death, not simply an underwater object to explore. A 500-meter exclusion zone keeps divers from approaching the site, where entering, touching, or removing material could disturb a grave or damage evidence preserved on the seabed.
Why set a boundary around it?
Underwater sites are difficult to monitor, and even a well-meaning visit can leave effects: a diver may disturb sediment, damage fragile remains, or take an object away. A clearly marked radius makes the rule easier to apply than trying to judge each visitor’s intentions at the wreck itself. The distance also keeps recreational activity away from a potentially hazardous site, without requiring visitors to know its precise condition.
For travelers, the restriction means the wreck is not something to approach for a closer look. The boundary is part of how Poland protects the site—and the people connected to it—from becoming an underwater tourist stop.
