Luxembourg (or Luxembourg City) is the rare example of a city-state in modern Europe—it serves as both the capital city and the name of the sovereign country itself.
Unlike most countries where the capital is a distinct city within a larger territory (e.g., Paris/France, Berlin/Germany), Luxembourg's identity merges the two. The city dominates the country politically, economically, and culturally.
A founding member of the EU, NATO, and UN, Luxembourg hosts several European Union institutions (European Court of Justice, European Investment Bank) and is a global financial center. Its historic fortifications and old quarters are a UNESCO World Heritage site.
