You’ll fly (or come via train) into Luxembourg City, so it makes sense to start your week in Luxembourg with two days in the city. Even though it has fewer than ninety thousand people, Luxembourg City is the hub of the country—both in history and in the present. However, remember that because the city is so small, most sights are only a few minutes’ walk away. Thus, you should feel free to rearrange this suggested itinerary, as you’ll never waste time going from one spot to another.
Our suggestion, however, is to start in the same place the country started in 963: the Bock Casemates. Siegfried, the Count of Ardennes, built a castle and fortifications in the city more than one thousand years ago, and the Bock Casemates are the oldest remaining fortifications.
You’ll spend the rest of the day exploring the various incarnations of these fortifications. Cross the castle bridge near the Bock Casemates; explore the underground tunnels and the archaeological crypt. Get on the Wenzel Walk (similar to Boston’s Freedom Trail) and explore the city’s historical sites and the Chemin de la Corniche—“Europe’s Best Balcony.” Finally, make sure you get down to the Petrusse Casemates, which date to the sixteenth century. Let’s Go Travel Guide suggests a picnic lunch in the Petrusse Valley in the shadows of these fortifications.
You’ll spend your second day at less military-minded sites. Start out at Place d’Armes, where you can get tourist information and great food. Then, head south a couple of blocks to the Cathedrale Notre-Dame. After viewing this church, stop by the Luxembourg City Historical Museum if you’re interested and then go to the Palais Grand Ducal, which is the home of Grand Duke Henri.
If you still have time and energy, consider the National Art History Museum; otherwise, return to your hotel for a brief rest, and then go explore the city at night. The Place d’Armes is often active and has great (albeit expensive) restaurants.
