Le passe-muraille (French: The Walker-Through-Walls), also known as Chambre sensorielle, is the name of a bronze sculpture created in 2006 by French sculptor Jean-Bernard Métais. It is located in the "Parc du Pescatore" in Luxembourg City and was set up over the old casemate-network of the city.
The sculpture is made out of two bronze hemispheres; it is 3 meters high and has a diameter of 6 meters. One can enter Le Passe-muraille through these hemispheres. 8,000 holes let the landscape shine through.
