M/S Maritime Museum of Denmark

Dark casemates, cannons and the Hamlet connection make this feel more adventurous than a palace full of furniture.

A small local aquarium with touch tanks and native sea life, easy to combine with the castle rather than making a separate day.

Planes, cars, machines and old technology give kids a warehouse full of big things to inspect.

The children's wing, sculpture garden and sea views mean kids do not have to spend the whole visit inside looking at paintings.

Multiple floors of hands on art activities make the museum much easier for younger kids to enjoy on their own terms.

The huge rooms and elaborate chapel make this the castle day most likely to impress school age kids.
