The Luxembourg underground tour is starting at the national bank BCEE Spuerkess (2, Place de Metz), with stopping points at the Fort Bourbon (Casemates), Bourbon Schléis (Péitrussdall), the Aqua-Tunnel (65 meter underground), Fort Berlaimont (Casemates), the 2 existing wells of the city (Rue des Bains & Place d'Armes) and is ending at the Place d'Armes.


During this visit, you will experience the atmosphere of the century-old hidden underground tunnel that served in World War II as emergency air-raid shelters, as bomb and shell-proof spaces during the time of Nazi occupation for General Omar Bradley's XIIth Army Group Headquarters and for Lt. Gen. George S. Patton deep under his 3rd army's Luxembourg Headquarters. These centuries-old underground fortifications became underground shelters of key US installations during the "Bulge" and beyond.
