Reffen

Contemporary art in huge halls, a free art workshop for all ages, and James Turrell's room of shifting colored light, where the walls seem to disappear.

Danish design in the old 1757 Frederiks Hospital, free under 17, with a sculpture garden where kids may climb the 'Playmates' figures.

Fetuses, skeletons and human remains collected since the 1700s, an exhibition on the gut and the brain, and a treasure hunt through the museum.

A leafy city park with a playground of playhouses, sandboxes and climbing elements.

The royal family's historic offices and the Gala Hall, a Fabergé room with a golden egg that opens to a hen, and the Royal Life Guard changing outside.

Old wooden beams overhead in a 1787 warehouse on the quay, a loft family room for two adults and two kids, and suites looking out over the harbor.
