Luxembourg, officially the
Grand Duchy of Luxembourg, is a small landlocked country in Western Europe. It is bordered by Belgium to the west and north, Germany to the east, and France to the south. Its capital and most populous city, Luxembourg City, is one of the four institutional seats of the European Union and the seat of several EU institutions, notably the Court of Justice of the European Union, the highest judicial authority. Luxembourg's culture, people, and languages are greatly influenced by France and Germany; for example, Luxembourgish, a West Central German dialect, is the only national language of the Luxembourgish people and of the Grand Duchy of Luxembourg, French is the only language for legislation, and all three – Luxembourgish, German and French – are used for administrative matters in the country.
