Luxembourg is a 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, Luxembourg City, is, together with Brussels and Strasbourg, one of the three official capitals of the European Union and the seat of the European Court of Justice, the highest juridical instance in the EU. Its culture, people and languages are highly intertwined with its neighbors, making it essentially a mixture of French and Germanic cultures. The repeated invasions by its neighbor countries, especially in World War II, resulted in the country's strong will for mediation between France and Germany and led to the foundation of the European Union.
