Museum of Copenhagen

Viking swords and silver treasure, plus the Sun Chariot, the Egtved Girl and the Gundestrup Cauldron in the prehistory galleries.

Strange, rare and hard-to-believe objects on Rådhuspladsen, run alongside the Guinness museum, a Wonder Maze and a walk through H.C. Andersen's fairy tales.

Rooms in the old 1912 central post and telegraph office, with a rooftop pool kept at 28 to 30 degrees all year by the hotel's own surplus heat.

The buffet is useful with kids because they can take tiny amounts of pasta, salads and vegetables until something works.

Room after room of statues in colors borrowed from the ruins of Pompeii, and free for anyone under 18.

A broad book selection near the square, with plenty of picture books.
