2 Best Sights in Copenhagen, Denmark

Situated at the western end of the lakes that divide Copenhagen, this modern, cylindrical planetarium appears to be sliced at an angle. It's Denmark's most advanced center for popularizing astronomy and space research and promoting knowledge of natural science. The on-site IMAX Theater is devoted to visual odysseys of the natural environment—below the sea, through the jungle, or into outer space. These films aren't recommended for children under age seven.

This Renaissance structure—built by King Christian IV and one of central Copenhagen's oldest—contains impressive displays of uniforms, weapons, and armor in a 600-foot-long arched hall. Children usually like this museum, but it's very much a look-but-don't-touch place. Each artifact has a label in English.
