Fun fact: Luxembourg may be one of Europe’s smallest states, but it boasts one of the richest Catholic monarchies still reigning today—and its Grand Duchess is a proud Latina, born in Havana, Cuba. The Grand Duchy of Luxembourg is the only sovereign Grand Duchy in the world. A devoutly Catholic country since its foundation, Luxembourg still recognizes the Church’s vital role in state life. Luxembourgish is their national language, but citizens are fluent in French and German too.
