Even if a museum – whose main attraction is an old ship from the bottom of the sea that couldn’t even sail – isn’t for you, try to stop by the Vasa Museum anyway. The ship was built as a prestige project by the Swedish king more than 350 years ago. The king was not one to be argued with, so when the king asked for higher masts and more guns, the shipbuilders said ‘Det är en bra idee’ (That’s a good idea). Unfortunately, this meant that the ship could not sail, and therefore sank on its maiden voyage – a few metres outside Stockholm Harbour. So for hundreds of years the ship lay forgotten, just 30 metres underwater, until it was rediscovered and raised in the last century. Now the impressively decorated and incredibly evocative ship is in a museum.
