A lovely day in Germany again. After visiting the Landschaftspark in Duisburg some weeks ago, we now went to Zollverein in Essen. Again, an industrial complex with a new function. These old coal mines now contain museums, restaurants and concert halls. Dutch architect Rem Koolhaas designed the beautiful escalators which take you to the top of the building and he also did a lot of the inside, like the orange staircase below. Really worth visiting when you're in the neighbourhood! More info here.
