Another must-see in Copenhagen is the Rosenborg. It’s a beautiful Dutch Renaissance style castle, that has a small base but was build high, reaching in the sky. It was used by Danish regents as a royal residence until 1710. Inside, you can visit the original rooms with baroque furniture transporting you back in time. Outside you can enjoy the country’s oldest royal garden. Rosenborg Castle Øster Voldgade 4 1350 København
