During World War II, Luxembourg abandoned its policy of neutrality, when it joined the Allies in fighting Germany. The government exiled to London set up a small group of volunteers, who participated in the Normandy invasion. It became a founding member of NATO and the United Nations. In 1957, Luxembourg became one of the six founding countries of the European Economic Community (later the European Union), and in 1999 it joined the euro currency area. Several European agencies are located in Luxembourg. In 2005 a referendum on the EU treaty establishing a constitution for Europe was held in Luxembourg.
Luxembourg is one of the smallest countries in Europe. It is ranked 167th in size of all the countries of the world. The country is about 2,586 km² in size. In the west it borders the Belgian province of Luxembourg, which is (at 4,443 km²) nearly twice the size of the country.
The north of the country, part of the Ardennes, has hills and low mountains, with the Buurgplaatz as the highest point at 559 m. The rest of the country is also hilly.
Luxembourg's eastern border is formed by three rivers, the Moselle, the Sauer/Sūre and the Our.
Cultural Notes:
Long a deeply rural and folkloric nation, Luxembourg retains folk traditions. Notable is the Echternach Dancing Procession which happens annually.
Luxembourg has little of distinctive architectural merit, but the military town of Denzelt in Echternach is on the Unesco World Heritage List.
