ARoS Aarhus Kunstmuseum
A hit from the day it opened in 2004, this museum displays the more than 8,000 artworks dating from 1770 to the present that make up its own, impressive collection, as well as internationally known visiting exhibits. There is a café, a museum shop, and a much-Instagrammed rooftop terrace in the form of a rainbow, an artwork by the Danish-Icelandic artist Olafur Eliasson.
