Traced two millennia ago, this Gallo-Roman road crosses the Beauce like a stone spire, linking the heart of Gaul to Autricum (Chartres) along a straight axis of astonishing precision.

History
In the heart of the Beauce region, between the communes of Semerville, Verdes, Membrolles and La Colombe, stretches one of the most striking testimonies to the Roman presence in Loir-et-Cher: an ancient road commonly known as the "Julius Caesar road" or the "Chartres road". Listed as a Historic Monument since 1978, this two-thousand-year-old artery has defied the centuries with a straightness that still commands the admiration of geographers and historians today. What distinguishes this route from the simple rural roads that dot the region is precisely its monumental character and its remarkable state of preservation. For several kilometres, the stony substrate, slightly higher than the surrounding terrain - characteristic of the Roman agger - remains visible in the landscape. The lateral drainage ditches, partially filled in over the centuries but still visible, bear witness to sophisticated road engineering designed to last. To travel this route is literally to follow in the footsteps of the legionnaires, sigillated ceramic merchants and imperial officials who linked the major towns of Lyonnais Gaul. The Beauce region, the granary of Antiquity, was criss-crossed by such axes that structured the land as surely as a bone framework. Here, the flatness of the Beauce plateau amplifies the sensation of a straight line stretching towards the horizon. Curious visitors can explore the site on foot or by bike, skirting the edges of farmland where, after deep ploughing, fragments of cut flint and tegulae sometimes emerge. The setting is unspoilt countryside, punctuated by arable crops, Romanesque church towers and the immense skies that have inspired so many painters from the nearby Barbizon school. A breathtaking experience, on the edge of time.
Architecture
The Gallo-Roman Semerville road has all the typical technical features of the imperial Roman roads of northern Gaul. Its most spectacular feature is the agger, a low hump that raises the carriageway from forty centimetres to one metre above the natural ground level, giving it an instantly recognisable silhouette on the Beauceron plain. On either side, lateral drainage ditches, now partially filled in, completed the hydraulic system that was essential on a clay plateau prone to waterlogging in winter. Depending on the section that has been preserved, the width of the road varies between four and six metres for the central carriageway, to which were added grassy verges allowing pedestrians and pack animals to walk outside the paved surface. The materials used reflect the local geology: flint from the Beauceron plateau, lacustrine limestone and alluvial material extracted from nearby quarries make up the bulk of the carriageway, bound by compacted sandy clay. The route itself is a geodesic feat: its straightness over several kilometres, through the communes concerned, bears witness to the mastery of triangulation techniques by the Roman agrimensores. Aligned on a generally north-south axis towards Chartres, the route ignored the minor topographical features of the plateau to maintain its direction with a consistency that remains impressive given the technology of the time.
