The Château d'Ancy-le-Franc (1538–1546), situated in the commune of Ancy-le-Franc in the French département of l'Yonne in Bourgogne, is an architectural masterwork by the Italian Sebastiano Serlio, conceived for Antoine III de Clermont (1498–1578), brother-in-law of Diane de Poitiers.

Deep in the Yonne, on the edge of the forests of Bourgogne, the château d'Ancy-le-Franc stands as one of the defining masterworks of the Italian-influenced French Renaissance. Its square silhouette — austere, perfectly ordered — sets it apart from the Gothic flights of fancy that characterise so many noble residences of the same period. Here, reason holds sway over ornament, and that very restraint becomes a form of rare magnificence. What makes Ancy-le-Franc truly singular is the absolute coherence of its architectural ambition: a perfectly square plan arranged around an interior courtyard, four symmetrical wings, bays punctuated by superimposed pilasters — a veritable manifesto of humanist thought rendered in dressed Burgundian stone. The building was conceived in the 1540s by the Bolognese architect Sebastiano Serlio, as much a theorist of architecture as a practitioner, who had been summoned to the court of François Ier. It remains the only château in France whose authorship is indisputably attributed to him. The interior reveals an altogether different order of richness. The royal apartments, galleries and grand reception rooms preserve some of the most complete cycles of mural paintings to survive in France from the sixteenth century. Certain coffered ceilings, painted wainscoting and monumental chimneypieces bear witness to the splendour of the Clermont-Tonnerre household, who made Ancy one of the great intellectual and artistic centres of Renaissance Bourgogne. A visit offers something increasingly rare: the experience of a château that remains alive in spirit, where rooms unfold in a continuous narrative, each one bearing a distinct layer of dynastic history. The formal French garden, carefully restored, extends the building's geometric rigour in perfect harmony, inviting a leisurely stroll between clipped hornbeam allées and sweeping monumental vistas. For the photographer, Ancy-le-Franc offers its pale golden stone façades caught in the warm morning light, reflections shimmering in the moat, and courtyard perspectives of an almost hypnotic symmetry. For the historian and the lover of art, it is an unmissable encounter with Renaissance humanism at its French apogee.
The Château d'Ancy-le-Franc is the purest expression in France of Renaissance classicism in the Italian manner. Conceived on an almost perfectly square plan, it is arranged around an arcaded inner courtyard rising across two levels, given rhythm by pilasters with superimposed Doric and Ionic capitals, ordered in strict accordance with the rules of antiquity. The exterior façades, deliberately restrained, command attention through their geometric rigour: no turrets, no ornate dormer windows, but a disciplined alternation of bays framed by flat pilasters and separated by crossette windows, the whole surmounted by a continuous cornice and a gently pitched roof. This reticence, almost unique in sixteenth-century French château architecture, speaks directly to Serlio's theories of beauty through proportion. The interior offers a striking contrast to this outward austerity. The galleries are adorned with frescoes and distemper paintings depicting mythological scenes, allegories and episodes from ancient history, executed by artists closely associated with the workshops of Fontainebleau. The coffered ceilings of painted and gilded wood, the monumental sculpted chimney pieces, the storied panelling and the glazed terracotta tiling together compose a decorative ensemble of exceptional richness for Bourgogne. The predominant materials are local blonde limestone, oak for the timber frames and joinery, and the flat Burgundian tile for the rooflines.
