Vasa Museum

So here is the story. It is sixteen twenty-eight, and the Swedish Empire has just built the most expensive, most heavily armed warship in the world. Sixty-four bronze cannons. Seven hundred carved sculptures. Gold leaf everywhere. King Gustav the Second Adolf personally approved the design, and nobody was going to tell the king his ship was wrong. Except the ship was catastrophically wrong. Before launch, they ran a stability test. Thirty sailors ran back and forth across the deck and the ship rolled so violently they had to stop after three passes or it would have capsized right there at the dock. The officer in charge looked at the results, looked at the king's expectations, and said nothing. On August tenth, the Vasa set sail on her maiden voyage in front of cheering crowds. She made it about thirteen hundred metres. A gust of wind hit, the ship heeled over, water poured through the open gun ports, and she went straight to the bottom. Thirty people died, including women and children who had been invited aboard for the celebration. The whole thing took about twenty minutes. Here is the incredible part. She sat on the seabed for three hundred and thirty-three years, and when they pulled her up in nineteen sixty-one, over ninety-five percent of the original wood was intact. The cold, brackish Baltic water lacked the shipworms that would have eaten her in any other ocean. It took seventeen years of spraying with a special wax called polyethylene glycol to preserve her. Over forty-five million people have visited since. You are looking at the world's most spectacular failure, perfectly preserved.
