I think this is only my second postcard from Liechtenstein, and quite possibly the only written and stamped one. For some reason I don't seem to have posted the other one here so here's the written and stamped one.
Vaduz Castle is the palace and official residence of the Prince of Liechtenstein. The castle gave its name to the town of Vaduz, the capital of Liechtenstein, which it overlooks from an adjacent hilltop.
Liechtenstein, officially the Principality of Liechtenstein, is a doubly landlocked German-speaking microstate in Central Europe. It is a constitutional monarchy headed by the Prince of Liechtenstein.
Liechtenstein is bordered by Switzerland to the west and south and Austria to the east and north. It has an area of just over 160 square kilometres and an estimated population of 35,000. Divided into 11 municipalities, its capital is Vaduz and largest town Schaan.
Economically, Liechtenstein has the highest gross domestic product per person in the world when adjusted by purchasing power parity. It is also the 2nd richest (by measure of GDP per capita) country in the world, after Qatar, and has one of the lowest unemployment rates at 1.5%.
An alpine country, Liechtenstein is mainly mountainous, making it a winter sports destination. Many cultivated fields and small farms are found both in the south (Oberland, upper land) and north (Unterland, lower land). The country has a strong financial sector centered in Vaduz, and has been identified as a tax haven. It is a member of the European Free Trade Association and part of the European Economic Area and the Schengen Area, but not of the European Union.
