Three large, open habitat sites (1 to 2 ha), dated to the end of the Bronze Age (-1400 to -800) and the First Iron Age (-800 to -450), yielded a large amount of pottery, a few stone artefacts, grindstones and a small quantity of faunal remains. These sites are characterized by numerous silos, large, polylobed pits, wells, buried ovens and several buildings on posts (granaries, houses?).

During the La Tène period (-450 à -50), a first plot layout system was implanted over several dozens of hectares. A habitat space, indicated by numerous wells, two silo burials, an oven, pits, a silo, storage vases and buildings on posts, extends over a humid zone of at least 2 hectares.
Two farms from the Final La Tène period (end of the Gallic period), located one kilometre apart, were excavated over a vast space in 2006 and 2008. They turned out to be very complex. One seems to have been abandoned under the reign of August, while the other seems to have remained in activity until the end of the 3rd century AD, and even to have been enlarged.

The Gallo-Roman occupation of this site is the best known. Though the 2008 excavation touched only a small portion of the heart of the habitat, the more fully excavated zones are already very intriguing. The fields, recognizable by a series of parallel trenches delimiting the cultivated plots, begin after a road. The farm buildings are visible on the other side of the road, where a second road joins the first. The entrance consists of a long courtyard delimited by a trench. On its south side, in the centre of a rectangular courtyard surrounded by walls, a 5 m wide stone tower was erected. This type of construction is characteristic of the large funerary mausoleums of Roman Gaul, implanted alongside roads. Next to the tower, the discovery of an adult buried in a coffin confirms this interpretation.
On the other side of the courtyard, other spaces surrounded by trenches are located side by side and continue beyond the excavated zone. In one of them, three babies were discovered buried in amphorae, along with two other individuals in coffins and a semi-buried stake the size of an adult male near the two tombs. A purse with 36 bronze coins attached to the belt of one of the skeletons has allowed archaeologists to attribute the burial to the end of the 3rd century, which is late relative to the creation of the farm. This site is complex and difficult to comprehend since it evolved through time. Who lived there? This enigmatic site seems to have first belonged to a eminent individual capable of instigating the construction of a large monument in his memory, following a typical Roman model. The site was then inhabited by a small population until at least the 3rd century. Numerous artefacts attest to varied activities. Animal husbandry is shown by the presence of bells worn by the animals, agriculture by the identification of fields and a sickle, woodcutting by a series of axes, ironworking by the presence of scoria and bronzeworking by a concentration of fragments of swords, pilium (lance) and jewellery that were to be remelted.

The 2008 excavation completed the data collected during the excavation of 2006. The excavated surfaces cut through several humid valleys that run into the principal stream that traverses the Parc. Pedological and geomorphological studies allow the researchers to follow the evolution of the landscape and rhythms of anthropization over several millennia (alternation of humid and dry period,s degree of landscape openness, etc.).
In proximity to the Fontenotte stream—exploited from the end of the Bronze Age to the Roman period—a modified spring and traces of paleochanels were discovered. Despite a restrictive, humid environment, the early populations were able to exploit and occuy the sector over several centuries. The fertility of the land, superior to that of many other zones in the department, partly explains the attractiveness of this area.
This project offers a relatively rare opportunity to comprehend this type of context in the Champagne-Ardenne region.

Most of the sites excavated in recent years are part of a habitat network so vast that the surfaces uncovered do not allow archaeologists to clearly define the limits of each site. This is the case for the habitat of Villeneuve-Saint-Germain, as well as for numerous Protohistoric agricultural installations. Concerning the Roman funerary complex, the diagnostic operation indicates its extension to be an additional 4 hectares. Over the whole project, the grouped occupations currently identified represent a minimum of 50 hectares, not counting the temporary occupations and "isolated" sites. In addition, the diversity of local contexts (humid zones, plains, woods), as well as the pedological data, explain the relatively good preservation of remains, including for the oldest periods. This project is particularly well adapted to the analysis of archaeological and environmental data and will thus contribute to a better understanding of the organization of this territory during several millennia of agricultural exploitation.
