The Blanc Mont american monument site is a former German observatory which saw more than 6,000 American soldiers perish. All the bodies and tombs were later assembled in Romagne-sous-Montfaucon (Meuse), but a monument was erected by the U.S. government in the 1920s on the battlefield itself.
The summit of the monument provides splendid views, enabling visitors to envisage what the battlefield looked like and to spot the remains of trenches. On 26 September 1918, French and American troops began the liberation of Sommepy.
The village, which had been completely destroyed, rose from its ashes thanks to the determination of its inhabitants and funds from America. A Memorial Room, located on the first floor of the Town Hall, retraces the history of this reconstruction.
