Round Tower

The Round Tower, or Rundetårn, is a 17th-century tower built as an astronomical observatory. It's particularly known for its wide, spiral ramp that leads to the top, making it accessible and a bit of a workout. Once at the summit, visitors are rewarded with sweeping views of Copenhagen's skyline. Throughout its history, the tower has served various scientific purposes and now hosts exhibitions and cultural events. Its unique architectural design, conceived by King Christian IV, makes it a distinctive feature in the city's urban landscape.
