AroS is one of Europe’s most beautiful contemporary buildings and a fantastic modern art museum. It contains seven floors of works from the late eighteenth century to the present day accessed from a centrepiece spiral walkway reminiscent of New York’s Guggenheim. The Skagen artists head the fine collection of home-grown art: the likes of Warhol are also represented along with the eerie five-metre-high Boy, by Australian sculptor Ron Mueck. The latest addition is the remarkable Rainbow Panorama, a circular rooftop walkway, fashioned in all colours of the spectrum, and offering wonderful city views.
