Luxembourg. Travel and Tourism. The Grand Duchy of Luxembourg is a landlocked country in Western Europe, bordered by Belgium, France and Germany. With a population of under half a million, Luxembourg occupies just under 1,000 square miles. It is a parliamentary democracy with a constitutional monarchy, ruled by a Grand Duke and, as such, it is the world’s only remaining sovereign Grand Duchy. Luxembourg is a founding member of the European Union, NATO, the United Nations, the Benelux countries and the Western European Union. The capital city, also called Luxembourg a UNESCO World Heritage Site is the seat of several European Union institutions and agencies. Its official languages are French, German and Luxembourgish, a High German dialect. Luxembourg is one of the smallest countries in the world and spans an area of just 1,650 square kilometers. With a population of 500,000 residents it is more like a large town than a country, but its size actually makes it a great place to visit as many of the main attractions are concentrated in one place. The center of the city is a UNESCO World Heritage Site in its own right and may of the top sights in Luxembourg can be found here. That’s not to say however that you should spend all your time in the city center, as if you take a quick journey out of town you will find a wealth of delightful towns and villages and much of the scenic countryside can be accessed by train. As well as picture-postcard enclaves you will also find aged fortresses and stunning castles, and it’s easy to visit Luxembourg by hopping across the border from the Netherlands or Belgium.
