Nestling in the Loirétain bocage at Aulnay-la-Rivière, Château de Rocheplatte is one of those rare buildings that combine seven centuries of history without ostentation. On the surface, an elegant 18th-century residence of harmonious proportions, framed by four circular medieval towers and surrounded by a white-water moat; at depth, a mysterious underground network of rib-vaulted passageways that plunge visitors into the deepest Middle Ages. What makes Rocheplatte truly unique is the coexistence of refined pleasure architecture - Louis XV pediment, carved woodwork, Parisian wrought-iron banisters - and a perfectly preserved medieval layout. The feudal square with its corner towers, typical of the fortresses of the Paris Basin, has not been erased but magnified, transformed into a showcase for the classical sensibility of the 18th century. The entrance via the three-arched basket-handle standing bridge provides a theatrical introduction: you cross the moat while watching the south facade open onto the courtyard of honour, whose cordon of nobility encircles the whole with aristocratic discretion. The return wings frame the space without overwhelming it, creating an intimate, luminous French courtyard. Inside, the Louis XV panelled drawing room boasts one of the most homogenous décors in the Centre-Val de Loire region: carved panelling, arabesque gypseries and a console fireplace - all of which bear witness to the care taken by the 18th-century patrons. The wrought iron staircase banister, taken from a Parisian town house, adds an unexpected urban elegance to the Sologne countryside. The real coup de théâtre is the descent into the medieval underground passageway: a nave with five ogival bays, two transepts forming a Lorraine cross, all carved out of the tufa chalk of the Beauceron plain. It's a space like no other, as intriguing as it is fascinating.
Château de Rocheplatte is based on a square plan of feudal origin, with the four circular corner towers forming the oldest structural element. Surrounded by a moat, the castle is encircled by a string of noble walls that emphasise the horizontal base and give the silhouette a sober elegance. Access is via a three-arched basket-handle standing bridge - a characteristic Louis XV taste for curved lines and generous proportions - which descends gently towards the paved main courtyard. The main dwelling, built in 1726, features a Louis XV-style triangular pediment on its south façade, supported by two wide pilasters. This central motif, crowned by a pavilion and a later Napoleon III dormer window, creates a play of verticalities that enlivens an otherwise strictly horizontal façade. Two wings in return complete the U-shaped plan, forming a protected inner courtyard. The materials used, probably Beauce limestone and Loire tufa, give the building the golden-blonde hue typical of Loiret châteaux. The interior is decorated to a very high standard: the living room is entirely panelled with Louis XV panelling carved with arabesques and floral motifs, while the large bedroom on the first floor to the east uses the same ornamental vocabulary. The wrought iron staircase banister, originally designed for a Parisian hotel, features exceptional wrought ironwork with scrolls and foliage typical of the Regency-Louis XV style. Last but not least, the medieval underground passageway is a technical masterpiece in its own right: a five-bay nave on ribbed crossbeams extended by two transepts forming a Lorraine cross, all dug into the tufa chalk, probably lit by candlelight and accessible from the moat via a well.
