Rosenborg Castle is a Renaissance castle located in the city centre of København, Denmark. It was built by King Christian IV in the early 1600s, and has since become a popular tourist destination. The castle is home to a large collection of royal artifacts, including coronation robes, æbleskiver pans, the Crown Jewels and more. Visitors are invited to explore the impressive royal chambers and historic grounds of the royal residence. With its picturesque gardens, romantic lakeside walks, and lush greenery, the castle is a must-see for anyone visiting København. Make sure you don’t miss the Armory Hall, with its lavish gilded ceiling and furniture, or else the Doll's House, a unique miniature of the 19th-century palace.
