Luxembourg is a small country located between Belgium, Germany, and France, and its culture is a good mix of German and French. With a GDP per capita of over €90,000, Luxembourg is the richest country in all of Europe and has been a hub of wealth for generations. Luxembourg may not be large, but it has plenty to see and do and fits nicely into any trip to Germany or France. The capital of Luxembourg City, known for its Medieval old town, is a charming place to spend some time as well.
