Combi Ticket for the Pétrusse Casemates & Aquatunnel (entry A)

Discover Luxembourg underground like never before with one unique ticket combining history, myth, and art.

Begin your journey in the Pétrusse Casemates, an extraordinary fortress system dating back to the 17th century.

Cutting-edge scenography and mesmerizing light installations bring the past to life and immerse you in an unforgettable experience.

From there, step into a completely different world in the Aquatunnel, a 900-metre passageway linking the Pétrusse Valley to the Pfaffenthal district. Once built for sewage and later repurposed for civil protection, the tunnel has been transformed into a multisensory art installation. Inspired by mythology and local legends, it draws visitors into an evocative soundscape: the songs of ancient sirens blend with the Luxembourgish tale of Melusine, creating an atmosphere that shifts between harmony, mystery, and enchantment.

With one combi ticket, you will:

Walk through centuries of history in the Pétrusse Casemates.
Experience art, legend, and sound in the Aquatunnel.
Explore two unique underground worlds with one ticket.

Book your Combi Ticket today and uncover Luxembourg’s hidden depths — from fortress walls to mythological echoes.
