Luxembourg: Aquatunnel Sound Installation ‘The Lower World’

If you’re looking for a unique way to experience Luxembourg’s urban landscape, the Aquatunnel Sound Installation ‘The Lower World’ offers a fascinating blend of art, history, and sensory exploration. While we haven’t personally wandered through it, reviews and descriptions paint a picture of an evocative experience that combines sound engineering with a walk through one of the city’s most historic sites.

What makes this experience stand out? First, you get to explore the 900-meter-long Aqua Tunnel—a corridor that holds significance as part of Luxembourg’s infrastructure and heritage.

Lastly, it’s an experience that invites reflection, with sounds ebbing and flowing like waves, echoing the city’s own layered history.

One thing to consider is the quiet, contemplative nature of the experience. As noted in reviews, maintaining silence and discipline can be challenging, especially in a group setting.

The Experience in Detail

Exploring the Aqua Tunnel

The Aqua Tunnel itself is a remarkable piece of Luxembourg’s urban fabric. Measuring approximately 900 meters, it runs through the Ville-Haute area, linking the Pétrusse valley to the Pfaffenthal district. This tunnel was originally part of the city’s infrastructure but has been repurposed into an art space thanks to this sound installation project.

Walking through the tunnel, you’ll notice its utilitarian design—concrete walls, rhythmic echoes, and an almost mysterious atmosphere. As one reviewer noted, it’s an environment that can feel cool or even slightly damp, so bringing a jacket is recommended. The length allows for a gradual immersion into the soundscape, with plenty of space for individuals to pause, reflect, or simply listen.

Sound Installation by Susan Philipsz

The core of this experience is the sound art broadcast through 12 loudspeakers positioned at various points within the tunnel. Philipsz’s work taps into themes of civil defense sirens—once a common sound in European cities—recasting them as both warnings and melodies.

Listeners will hear the sirens fluctuating from melodic, melancholic, dissonant, to haunting tones. This dynamic soundscape mimics waves, rising and falling, creating a sense of movement and emotional depth. As one visitor described, “the sound of the sirens becomes a current that seems to rise and fall in waves,” emphasizing the immersive quality of the piece.

Reflection and Atmosphere

The experience is designed to be contemplative. You’re encouraged to reflect on your environment and the sounds you hear, which evoke both the city’s past and present. The subtle broadcast of Philipsz’s voice—likely a recording of her own—adds a human element to the otherwise industrial soundscape.

However, as one review shares, participants need to maintain silence and discipline for the full impact. “It’s nice to be there, but the experience itself is disappointing,” a reviewer commented, mainly because group noise can detract from the ambiance. The installation’s best moments come when you can truly listen without interruption, making it a meditative experience rather than a guided tour.

Is This Experience Worth It?

When evaluating value, consider the unique art environment and the location’s historical importance.

Authentic Experience According to Reviewers

One reviewer pointed out that “the guide was very kind and let us walk back with them so we could experience it on our own,” hinting that flexibility and personal space are part of the appeal. Another mentioned the challenge of keeping a quiet group, which is a reminder that this is more about personal reflection than guided storytelling.

Not suitable for small children, those with mobility issues, or anyone sensitive to confined spaces or loud sounds.
