Chronicle the Round Tower

Why walk when you can spiral, right? The Round Tower, or Rundetaarn, is the place to get your helix on. This 17th-century tower is a true path to the stars with its eponymous round walkway leading you all the way up. You aren't just walking; you're ascending a piece of architectural candy! And once you reach the top, bam! Copenhagen is sprawled out before you like a smorgasbord of urban delight.
