The Copper Tower or Plesner Building is just a stone throw away from the statue of the Little Mermaid on Langelinie Warf. It's covered in copper plating, and therefore it started out flaming red (I haven't got a picture of that), then turned brown but as the copper oxidise further it'll turn green in the next couple of decades. Built in 2004 it houses the international law firm Plesner and has shops and cafe´s on the ground floor.
Just across from it are the ferries to Norway and Poland, and next to it is a little old building; a former train station. The train station is preserved and so can't be torn down or moved.
