Vaduz ( or, High Alemannic pronunciation: []) is the capital of Liechtenstein and also the seat of the national parliament. The city, which is located along the Rhine River, has 5,696 residents. The most prominent landmark of Vaduz is Vaduz Castle, being 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.
The name of Vaduz had been first recorded as de Faduzes. The name of the settlement, like most other towns in the Rhine Valley region, is of Romance origin. The name can be traced back to Old Rhaeto-Romance root auadutg, meaning aqueduct, which in turn evolved from the Latin aquaeductus.
