Aarhus

Aarhus is compact enough to cover on foot in a day, and most of the good stuff is near the harbour. Den Gamle By, an open-air museum built from relocated historic buildings, is genuinely interesting rather than the usual tourist-bait reconstruction. ARoS art museum has a rainbow-coloured glass walkway on the roof that gives you a 360-degree view of the city through tinted panels. The street food market in a converted bus garage is the easy lunch option — Danish smørrebrød next to Vietnamese and Mexican stalls, all decent. The Latin Quarter has smaller cafés if you want something quieter. Aarhus was a Viking settlement originally, and there's a small museum downtown with artefacts from that period. The waterfront promenade along Åboulevarden fills up on sunny afternoons with locals drinking coffee.
