You just discovered the Grand-Duchy of Luxembourg’s capital as a pleasant and lively city, packed with history and culture!
Very few people are aware that there is a “secret” Luxembourg underground separate from the world-famous “casemates”. Together with our partner “Friends of Luxembourg Fortress History" asbl - FFGL, we offer exclusive, small group tours to the hidden underground centuries-old tunnels and galleries that even served in WWII as emergency air-raid shelters during the years of occupation and as “just in case” bomb and shell-proof spaces for Gen. Omar Bradley’s XIIth Army Group Headquarters (Eagle Tac) (December 1944) and for Lt. Gen. George S. Patton, jr.’s Headquarters (December 1944 - March 1945) deep under his 3rd Army’s Luxembourg headquarters.
In other words: centuries-old underground fortifications became “just in case” key US installations in “modern warfare” during the “Bulge” and beyond.
Visits must be pre-arranged at least 3 weeks before.
Not recommended for people with mobility problems and suffering from claustrophobia!
Good walking shoes and a jacket (also in Summer) strongly recommended.
