Kronborg Castle in Elsinore is a UNESCO world heritage site; these come with severe restrictions on nearby development. You can't build new buildings that significantly change the view from the site. When the castle was recently renovated, there was no longer room for the old Maritime Museum that occupied part of it since 1915, so it was decided to build a new museum in the old dry dock nearby. An invited competition was held to choose the architect, with the expectation that the museum would actually be in the dock, but Bjarke Ingels rarely does what is expected. He ignored the program and proposed building the museum around the dock, leaving it mostly open except for circulation.
