Built by King Christian IV in the early 17th century, this Dutch Renaissance gem houses the Crown Jewels, priceless artifacts, and the magnificent Throne Chair of Denmark. Visitors stroll through lavish halls adorned with Flemish tapestries and original artworks before exploring the adjacent King's Garden - a charming public park with symmetrical lawns, fountains, and seasonal blooms. Just a short walk from Nørreport Station, the castle blends regal grandeur with urban accessibility, making it a must-see alongside attractions like Nyhavn and the Round Tower.
