Liechtenstein is the smallest European country by land area among states that use a national currency other than the euro.
Liechtenstein covers about 160 square kilometres in the Alps between Switzerland and Austria. Its official currency is the Swiss franc, not the euro, although euros may be accepted in some places. Vaduz is the capital, and the country is a constitutional hereditary monarchy.
Liechtenstein’s position is distinctive because several even smaller European states use the euro, including Monaco, San Marino, Andorra and Vatican City. Liechtenstein instead has a close economic and customs relationship with Switzerland and has used the Swiss franc since 1924.
The country is also one of the world’s two doubly landlocked states, meaning every route to the sea crosses at least two other countries. That geographic fact is separate from its currency distinction.
