In 1911, the small village of Moronvilliers had only 86 inhabitants. Now, the 3,152 ha village has over 1,376 inhabitants.
On 2 September 1914, the village, only 15 km north-east from Rheims, was occupied by German troops that had captured the area during WWI. After this incident, the village was deserted and destroyed during the war. Although it was never rebuilt, from 1950 Moronvilliers has shared its territory with Pontfaverger as the new village, Pontfaverger-Moronvilliers.
The town of Moronvilliers has been the site of so-called "dry-nuclear" testing in the the past, which caused many issues with both the general public and foreign observers.
