• Navy days close the ship, as she still hosts official ceremonies at a day's notice, so check the museum's website or Facebook before going
• Tickets at the ticket office, not online, and a visit aboard takes up to 30 minutes

ORP Błyskawica is a 114-meter Polish Navy destroyer launched in 1936 at Cowes on the Isle of Wight, and the oldest surviving destroyer in the world. She fought through all of World War II, from the Dunkirk evacuation to the Normandy landings.

Now a museum ship moored in Gdynia, she still flies the naval ensign and keeps her own crew, and hosts official Navy ceremonies.
