Listed as a World Heritage site by UNESCO, the town of Luxembourg is home to a large number of curiosities. Its tourist trails and its historical sites (the baroque cathedral and the Palace of the Grand Dukes) never fail to delight history lovers. Enjoying a strategic geographical location, Luxembourg is a European crossroads in every sense of the term. The presence of numerous European Union organs and institutions makes the town a leading player on the international scene. These include the Court of Justice of the European Communities, the Court of Auditors, the Permanent Secretariat of the European Parliament, Eurostat, the Statistical Office of the European Communities, the Translation Service, the Office for Official Publications, and the European Investment Bank. A relatively small town when compared to other international cities, Luxembourg nevertheless remains a dynamic and cosmopolitan city, and is well worth a visit.

Pierre Werner was one of the guiding lights behind economic and monetary union. This politician from Luxembourg influenced the history of his country as a finance minister and head of government for more than 20 years, but also left his mark on the process of European construction by proposing the creation of a European economic union. In March 1970, he chaired a special study group which drew up a report proposing a three-stage process to introduce a single currency, a plan which was subsequently re-named the “Werner Plan”. Although the aim was to introduce this union before the end of the decade, the project was nevertheless delayed by the world monetary crisis of 1971 and the oil crisis of 1973. Europe therefore had to wait until economic stabilisation occurred in 1979 for the first stage of the Werner plan to be implemented, with the creation of the European Monetary System (EMS). However, it was only on January 1st, 2002, more than 30 years after the plan had first been submitted to the six founding Member States, that Pierre Werner finally saw his dream turned into reality, with the introduction of the euro, just six months before his death.

Coveted over the centuries by major foreign powers, the Grand Duchy of Luxembourg found it necessary to build many castles. Of the 109 castles listed in the Middle Ages, 76 have stood the test of time and are in various states of repair. From both a historical and touristic point of view, the most interesting of these are the castles of Beaufort, Bourglinster, Bourscheid, Clervaux, and Vianden. The castle of Beaufort was built around 1200. Its ruins are spectacular and well-maintained, located in an attractive setting. The castle of Bourglinster is built on a rocky spur, at a height of 350 meters. The castle of Bourscheid, the largest of the country, is located between the Rhine and the Meuse. In 1430, the great outer wall was added, with its many towers. The medieval castle of Clervaux is also well worth a visit. Built in a winding valley, this feudal castle dates from the 12th century. The castle of Vianden was one of the largest and finest feudal residences in Europe during the Romanesque and Gothic periods. For anyone keen to get back to the days of knights in shining armour, nothing can rival a stay in Luxembourg!

Robert Schuman
Robert Schuman, one of the fathers of the European Union and the author of the declaration of May 9th, 1950, (which is generally considered to have laid the foundations for the European Union), was born on June 29, 1886 in Luxembourg-Clausen, from a father of Lorraine and a mother of Luxembourg. He stated: “It is not by accident that the idea for a steel, iron and coal community has come from a boy from Luxembourg, whose parents lived through the war”.

Small fortress
It is easy to understand why Luxembourg is so famous for its castles when we bear in mind that the name Luxembourg is derived from the word “lucilinburugh” which means “small fortress”.
Three official languages
Luxembourg has three official languages: Luxembourgish, French and German. Luxembourgish is taught at school after French and German. The trilingual nature of this country is a fitting symbol of its outward-looking spirit and its hospitality.
