This peculiar looking, partially glass, building in the HafenCity will probably draw your curiosity, and it has a slightly amusing history. It is a concert hall built on top of an old warehouse, giving it the infamously odd appearance. The construction of this building has cost Hamburg a lot of money and time! Which is why to some people from Hamburg the building is something to ridicule, or view with distain! It doesn't officially open until 2017, but whilst you're exploring the HafenCity stop to look at the controversial building and see if you think it was worth all the money it cost to build.
