Things to do in Luxembourg City

In the northeastern corner of the old town (known as ‘Bock’), where major fortifications once stood, the Casemates du Bock remain as a reminder of times past. These 17th century defense galleries actually served as underground tunnels for Luxembourg residents during World War II. Today, you can take a guided tour – but be prepared for slippery surfaces, steep stairs and extremely narrow staircases in the lower passages. Claustrophobic? Stay in the upper passages.

The Pont Adolphe arch bridge, built in the early 20th century, has become a symbol of Luxembourg’s independence and is one of the most popular attractions in the country. More than 100 years old, the bridge that was constructed after the city’s fortification walls were torn down. It is still the primary link between the two halves of the city.

The Palace of the Grand Dukes (Palais Grand Ducal) stands proudly in the heart of the old town. Originally Luxembourg's city hall, this 16th century structure now serves as the official residence of the Grand Duke. The Dent Creuse castle, whose name translates as 'Hollow Tooth', was originally built in 965 A.D., but the tower is the only part of the castle that has survived the ages. The highlight of this attraction is the panoramic views of the towns below and the surrounding plateaus.

The site of Saint Michael’s Church (Église Saint-Michel) dates back to 987, but the church you’ll see was actually constructed in the late 17th century and features a myriad of archeological styles, including Romanesque, Gothic and Baroque. The city also has the Notre-Dame Cathedral, a beautiful 17th century example of Gothic and Renaissance architecture.

The old town is concentrated between two main squares – Place d'Armes and Place Guillaume II. Here, you’ll find shops, restaurants, cafés and sights for the whole afternoon. On your way out, don’t miss the Luxembourg City History Museum (Musée d’Histoire de la Ville de Luxembourg). It has a glass elevator that reveals the old town’s ‘rocky’ past, by displaying the underlying geology of the area.
