Luxembourg (also known as Luxembourg City), is the capital city of the Grand Duchy of Luxembourg (also named "Luxembourg"), and the country's most populous commune. Standing at the confluence of the Alzette and Pétrusse rivers in southern Luxembourg, the city lies at the heart of Western Europe. The city contains Luxembourg Castle, established by the Franks in the Early Middle Ages, around which a settlement developed.
As of January 2019, Luxembourg City had a population of 119,214, which is more than three times the population of the country's second most populous commune (Esch-sur-Alzette).
In 2011, Luxembourg was ranked as having the second highest per capita GDP in the world at $80,119 (PPP), with the city having developed into a banking and administrative center. In the 2011 Mercer worldwide survey of 221 cities, Luxembourg was placed first for personal safety while it was ranked 19th for quality of living.
Luxembourg is one of the de facto capitals of the European Union (alongside Brussels and Strasbourg), as it is the seat of several institutions, agencies and bodies of the European Union.
