Motte castrale
FortressHidden Treasure
An enigmatic silhouette rising out of the plains of Beauce, the motte castrale at Prasville bears rare witness to the feudal organisation of the 10th-12th centuries, its intact moats an invitation to step back in time.

History
In the heart of the Beauce region, between cereal fields and endless horizons, the motte castrale at Prasville stands as a discreet but striking vestige of medieval feudalism. This man-made mound, some forty metres in diameter, retains the silhouette of a flattened truncated cone that ten centuries of rain and wind have not been able to erase. Surrounded by a wide dry ditch - now converted into a country lane - it evokes with disconcerting sincerity the daily lives of the warriors and peasants who lived in its shadow. What sets the motte de Prasville apart from the countless similar mounds once scattered across the Beauce region is above all its state of preservation and the apparent absence of any low courtyard to date. Where other sites have seen their topography erased by ploughing or urbanisation, this eminence has survived, offering archaeologists and heritage enthusiasts an almost legible insight into primitive fortification techniques. The ditch that surrounds it, transformed into a path by rural usage, is in itself an initiatory journey around this earthen castle. It's an open-air archaeological experience, to be enjoyed on foot, taking the time to walk around the mound to grasp its volume and imagine the wooden tower that once crowned its summit. You'll look out over the surrounding plains, reminding you that this artificial promontory was primarily used as an observation post and to assert the power of the lords over an agricultural territory. The site is set in a typical Eure-et-Loir landscape of hedged farmland, just a stone's throw from Chartres and its vast cereal-growing plains. Away from the tourist crowds, Prasville offers an authentic immersion into a rural Middle Ages that is often little-known, that of local lords whose names have been lost but whose determination to territorialise the area remains engraved in the very earth.
Architecture
The motte castrale at Prasville displays the classic morphology of this type of defensive structure typical of the 10th-12th centuries: a truncated cone flattened at the top, rising above the surrounding plain, with a base diameter of around forty metres. This truncated cone shape is not the result of chance, but of proven defensive logic: the slope of the sides slowed down any attempt to climb, while the small summit plateau concentrated the wooden residential and defensive tower that originally stood there. The most remarkable feature of the site is the wide, well-preserved perimeter ditch, which encircles the entire mound. This dry ditch - unlike the water moats of later castles - served a dual function: on the one hand, it provided the earth needed to raise the mound during construction; on the other, it formed a natural defensive obstacle forcing any attackers to expose themselves in the hollow before attacking the slopes. Reconverted into a country path by local custom, it remains perfectly visible in the landscape. No trace of a lower courtyard has been found to date, which could indicate either an organisation focused on the motte alone, or the early destruction of the ancillary structures. The building materials used were essentially earth and wood - typical of this period - which explains the absence of visible masonry ruins on the surface. The motte at Prasville therefore belongs to the most archaic and widespread type of French medieval fortification, predating the widespread use of stone keeps.
