Thorvaldsens Museum

Dark underground foundations and old castle remains feel much more adventurous than touring another formal room.

The royal rooms are impressive, but the underground ruins are often the more interesting part for kids.

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

Cannons, armor and military equipment give kids lots of big physical objects to look at instead of tiny things in cases.

Viking objects, mummies and the children's area make this a much easier history stop than the building suggests.

Kids can climb into historic rooms, dress up and play through Danish history instead of just looking at objects.
