A special kind of preservation that takes place in the Netherlands is the preservation of maritime heritage. Maritime trade was the Dutch specialty which shaped much of their culture and as a country that is 50% under sea level the Dutch history is closely intertwined with water. There are maritime museums in both Amsterdam and Rotterdam that tell the story of the Dutch maritime heritage, but there is not much legal documentation on how to preserve it. For example, according to Sarah Dromgoole, shipwrecks from The Dutch East India Company are found all around the world, which are still property of the Netherlands, but the Dutch government rarely takes responsibility for this property that is found outside of their territory.
