Vaduz is the capital of Liechtenstein and also the seat of the national parliament. The city, which is located along the Rhine, has 5,696 residents. The most prominent landmark of Vaduz is Vaduz Castle, perched atop a steep hill overlooking the city. It is home to the reigning prince of Liechtenstein and the Liechtenstein princely family. The city's distinctive architecture is also displayed in landmarks such as the Cathedral of St. Florin, Government House, City Hall, the National Art Gallery, as well as the National Museum. Although Vaduz is the best-known town in the principality internationally, it is not the largest; neighbouring Schaan has a larger population.

Liechtenstein, officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate located in the Alps between Austria and Switzerland.
