« NUTS! »— General Anthony McAuliffe, Written response to German General von Lüttwitz, December 22, 1944
The story that haunts this land
Bastogne awakens on December 16, 1944 under the shells of the Battle of the Bulge, Hitler's last desperate attempt to reconquer Western Europe. Place Général McAuliffe, then a simple market square, becomes the scene of clashes between the 26th Panzergrenadier SS Division and American paratroopers. The Sherman M4A3E8 'Easy Eight' tank that stands before you today is an authentic vehicle from Patton's 3rd Army, silent witness to these urban battles where every street, every house became a bastion of resistance.
Bastogne's Town Hall, this 18th-century neo-classical building, changes hands several times during the siege. Used as German headquarters during the first days of the offensive, its facade still bears the scars of the December 23, 1944 bombings. Henri Bailly, mayor of Bastogne since 1940, coordinates civilian evacuation while the SS transform its salons into a command center. Every window of this facade, restored after 1945, witnessed European history at war.
Saint-Pierre Church, built between 1778 and 1783, becomes an improvised refuge for American wounded from the 101st Airborne Division. Its 45-meter bell tower, visible from 5 km away, serves as an observation post for snipers from both sides. On December 23, 1944, German bombings damage its nave, but stretcher-bearers continue treating soldiers under the cracked vaults. Restored in 1950, it keeps in its stones the memory of those days when faith and war mingled under one roof.
The 101st Airborne Division Monument marks the exact location of the headquarters where Anthony McAuliffe pronounced his famous 'NUTS!' on December 22, 1944. This statue of the general, unveiled September 15, 1946, bears the inscription 'To the people of Bastogne from the men of the 101st Airborne Division'. The Old Post Office, this 1932 Art Deco building, was requisitioned by Germans as command center for the 26th Panzergrenadier SS Division. Restored in 1952 after partial destruction, it illustrates Bastogne's civilian reconquest after the war.
Your journey concludes at Mardasson Memorial, this colonnade of 48 pillars erected in 1950 on 11 hectares, 2 km from the center. Inaugurated by Crown Prince Baudouin on July 30, 1950, this national memorial honors the 76,890 American soldiers who died or were wounded during the Battle of the Bulge. Its crypt, adorned with Jean Rouvet's frescoes since 1954, traces this epic where Bastogne became the symbol of Allied resistance. You leave with more than a history lesson: an intimate understanding of these 10 days that saved Europe from Nazi barbarism.
