Liechtenstein

Vaduz is the capital of Liechtenstein, serving as the seat of the Prince and the parliament (Landtag). It’s a small city in the Upper Rhine Valley, famous for Vaduz Castle overlooking the town. The other options are from neighboring countries: Zurich and Geneva are in Switzerland, and Innsbruck is in Austria. Liechtenstein is a tiny, doubly landlocked principality between Switzerland and Austria; interestingly, Vaduz isn’t even its largest town (that’s Schaan). Memory tip: Think “V for Valley Vaduz” — the capital sits in the Rhine Valley — and “V for Vaduz, View of the Castle.” Also, tie the two “V”s together: Liechtenstein’s capital and its iconic castle both start with V, making Vaduz easy to remember.
