Explanation:

Vaduz, the capital of Liechtenstein, sits on the Rhine River near the Swiss border. On a hillside overlooking the town, Vaduz Castle dates back to the 12th century and is a royal family residence. In the Städtle, the pedestrianized town center, the sleek Kunstmuseum Liechtenstein displays modern art. Nearby, the National Museum houses archaeological and cultural artifacts in a medieval building.
