Luxembourg City

A thousand-year-old fortress city built above deep gorges, with its old town and fortifications a World Heritage Site, a distinctive Grand Ducal Palace and underground casemates, and free public transport to Vianden Castle and Little Switzerland.

Luxembourg City is the capital of the Grand Duchy of Luxembourg and home to institutions such as the Court of Justice of the European Union and the European Investment Bank. The old town sits on a sandstone plateau carved out by the Alzette and Pétrusse rivers, where successive rulers built layer upon layer of fortifications, earning it the nickname "Gibraltar of the North"; the old town and fortifications were listed as a World Heritage Site in 1994. The city has three levels: the old town on the plateau (Grand Ducal Palace, Notre-Dame Cathedral, squares and museums), the valley neighborhoods of Grund and Clausen below the cliffs, and the European institutions and modern architecture (Mudam, the Philharmonie) on the Kirchberg plateau to the northeast. Free public elevators and a funicular link the levels, and since 2020 all public transport nationwide has been free. The weather is most pleasant May–September; July–August brings open-air music and guided tours of the Grand Ducal Palace, and December has Christmas markets; winters are cold, gray and rainy, and the casemates close. The city can be seen in 1–2 days, then spend another 1–2 days by train and bus visiting Vianden Castle and Clervaux in the northern Ardennes, the Mullerthal "Little Switzerland" and Echternach in the east, or the Moselle wine region in the southeast. There are direct trains from Frankfurt, Brussels and Paris. Prices are high, and most shops are closed on Sundays.
