Djurgården

This guide to Djurgården in Stockholm poses one puzzle: how do you save a wooden ship that spent three hundred thirty-three years dissolving at the bottom of a harbor. You'll hear the story of the warship Vasa's minute-long maiden voyage in 1628, the admiral who halted a stability test three passes in and was overruled anyway, and what three centuries in cold Baltic water did to her oak once divers raised her in 1961. Listen for how engineers are still working today, correcting a centuries-old sag in the hull in front of you.
