Thorvaldsens Museum

800-year-old ruins under the palace, the royal stables, and tapestries of 1,000 years of Danish history, one showing the queen with her dachshunds.

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

Samurai swords, tanks and decorated cannons in Christian IV's old arsenal, with free entry for under-18s.

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

A Pick-A-Brick wall for buying loose bricks by color and shape, LEGO models on display around the store, and a play area in the middle for building.

Crafts, stationery, kids' games and toys, with classical music playing and new things on the shelves every week.
