Maison dite La Maison à trois carres, located in Le Pêchereau (Indre), is a Renaissance château built in the 16th century. The monument is currently closed to visitors.
The only one of its kind in France, this 18th-century triangular house was built in 1786 as a living Masonic manifesto: plan, facades and grounds in the shape of a triangle, a symbol of the Enlightenment inscribed in Berry stone.

Perched on the hills overlooking the Creuse valley, at Le Pêchereau, a stone's throw from Argenton-sur-Creuse, the Maison à trois carres is one of the most unusual architectural curiosities of 18th-century France. Its name, which in old French refers to the angles or faces, immediately reveals the originality of its shape: a rigorously triangular plan, as rare in French civil architecture as it is eloquent in its symbolism. What radically distinguishes this little country house from all the architectural follies of its time is precisely its asserted modesty. Whereas the great architects of the period - Ledoux, Boullée and Brongniart - took pleasure in designing spectacular geometric forms for powerful clients, the Maison à trois carres is a rural, functional, lived-in house. Its Masonic message is not one of ostentation, but of form itself, discreet yet perfectly legible to those who know how to see. To visit this place is to immerse yourself in the intellectual world of the Age of Enlightenment as it radiated out to the villages of Bas-Berry. It's easy to imagine Jean-Baptiste Brunet, an officer of the maréchaussée and a convinced Freemason, gazing out from his terrace at the vines that covered the slopes, aware that he was living in an idea as much as a house. Each corner of the house is reminiscent of the triangle, the central symbol of the Masonic tradition, present in the rituals, lodge decorations and philosophy of the Order. The natural setting adds a contemplative dimension to the visit. Surrounded by ancient vineyards and overlooking the meandering Creuse river, the house offers a sober and authentic panorama, far from the beaten tourist track. It's a monument for the curious, lovers of the history of ideas and enthusiasts of "talking architecture", the eighteenth-century trend to make the shape of buildings speak even before you cross the threshold.
The Maison à trois carres derives its absolute originality from its triangular plan, which determines all its formal characteristics. Each of the three façades forms a side of the triangle, and the entire plot of land on which it stands follows this same geometry, reinforcing the symbolic coherence of the whole. This arrangement, rare in French civil architecture, brings the building closer to the theoretical projects of revolutionary architecture - but on a modest, rural scale, which makes it all the more unique. The building is a late eighteenth-century bourgeois country house, without excessive ornamentation or ostentatious monumentality. The materials used are those of the Berrichon region: local stone masonry gives the building a sobriety that paradoxically reinforces the impact of its geometric shape. The roof, adapted to the constraints of the triangular plan, is also a discreet technical feat for the contractor who was responsible for it, having to solve the assembly problems posed by a converging three-sided roof. Inside, the layout of the rooms is based on the same triangular constraint, creating rooms with unusual geometries and characteristic acute angles. Although the interior layout has undoubtedly been adapted over the centuries, the load-bearing structure retains its original imprint. Together, they form a coherent, intact testimony to a form of architecture that speaks for the province, in which geometric form takes precedence over any other decorative considerations, inscribing in stone the philosophical convictions of its patron.
