On the borders of Berry and Limousin, the Chaussée de l'Étang has crossed the Portefeuille stream since the Middle Ages. This discreet monument, listed in 2011, bears witness to eight centuries of rural hydraulic engineering.

History
In the heart of the Boischaut Sud region, in this land of hedged farmland and rivers that the Berrichons call the "Petite Creuse", the chaussée de l'Étang is one of those structures that people pass through without always realising their age and heritage value. Now carrying the departmental road no. 1 linking Le Blanc to Saint-Benoît-du-Sault and Limoges, this dyke spans the Portefeuille stream with the quiet solidity of the great rural constructions of the 18th century. What makes this structure truly unique is its dual nature: living road infrastructure on the one hand, and evidence of medieval hydraulic engineering on the other. Where so many old roadways have disappeared under consolidation or modernisation, this one has survived the centuries without losing its form or function. It links two communes - La Châtre-Langlin and Saint-Benoît-du-Sault - just as it did under the Ancien Régime, when it was administratively part of the provostry of Saint-Benoît-du-Sault. A visit to the dyke is ideal for those interested in rural heritage and the history of technology. As you walk along the dyke, you can appreciate the scale of the work carried out by engineers and craftsmen at the end of the 18th century to consolidate and widen a much older structure. The immediate surroundings offer a rural panorama typical of the Creuse Berrichonne region: willows and alders leaning over the dark water, rolling meadows, silence punctuated only by the murmur of the Portefeuille. The official recognition of this modest but exemplary infrastructure came in 2011 when it was listed as a Historic Monument. It is a reminder that heritage is not just about castles and cathedrals, but also about the rural engineering structures that have shaped the landscape and organised trade for centuries. For the attentive photographer or the curious walker, the Chaussée de l'Étang offers an authentic experience, far removed from the tourist crowds.
Architecture
The chaussée de l'Étang belongs to the family of road dykes, hybrid structures that combine the functions of hydraulic retention and road crossing. On the Ruisseau du Portefeuille, the structure takes the form of a consolidated masonry or earth embankment, with a slightly cambered cross-section to ensure both rainwater run-off and structural stability in the face of the pressures exerted by the upstream reservoir. The materials used in the reconstruction in the second half of the 18th century are typical of local techniques: cut or simply squared Boischaut granite and sandstone, bonded with local hydraulic lime. The side facings, where they are visible, bear witness to the particular care taken over the quality of the workmanship, a sign that the work was a public commission and not simply a peasant initiative. The roadway stretches over a significant length, creating a stretch of water upstream - the eponymous pond - the size of which may have varied depending on the era and usage. The sobriety of the whole is typical of 18th-century rural civil engineering: no superfluous ornamentation, total functional efficiency. It is in this very austerity that the elegance of the structure lies, fully integrated into a landscape of hedged farmland where grey stone and dark water meet under the changing skies of southern Berry.
