Most visits to Liechtenstein are trouble-free but you should be aware of the global risk of indiscriminate international terrorist attacks, which could be against civilian targets, including places frequented by foreigners.
Liechtenstein is a small nation that shares border with two of the most beautiful countries of Europe, Switzerland and Austria.
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.
