The Swiss Frank (plural: Franken) has been the currency of Liechtenstein since 1920. The Swiss franc is legal tender since Liechtenstein is in a customs and monetary union with Switzerland. The 1980 treaty between Switzerland and Liechtenstein allows Liechtenstein to mint Swiss franc coins, but not to issue banknotes.
Art and culture are everywhere in Liechtenstein. The art collections of the Prince are certainly one of the greatest attractions. But also galleries, theater, cinema, and concerts will touch all your senses.
Over the past few years Vaduz, the capital of Liechtenstein, has become more and more the center of the whole region, and houses not just the Parliament but has been the residence of the Prince since 1938. Vaduz was first mentioned in documents in 1150.
