In the heart of the Drouais, a small region of the Eure-et-Loir shaped by the Norman marches, the church of Saint-Blaise de Tréon stands out as a survivor. Where its neighbours have undergone the successive alterations of the Gothic period, the Counter-Reformation and the 19th century, Saint-Blaise has preserved the essence of its Romanesque silhouette, essentially unchanged since the first quarter of the 12th century. It is this rarity that led to it being listed as a Historic Monument in 2013, and to its quiet but solid reputation among lovers of medieval art. What makes Saint-Blaise truly unique in the Drouais landscape is the coherence of its Romanesque architectural vocabulary: a soberly proportioned choir, bays framed by finely-moulded semi-circular archivolts, and above all a voussuré portal that betrays a sculptural mastery of Norman influence. At a time when the Duchy of Normandy was spreading its influence throughout the region, the stonemasons who worked here brought with them a wealth of expertise that can be seen in the craftsmanship of the decoration and the geometric rigour of the profiles. The interior is full of surprises that time has yet to reveal. The painted roof frame is a rare example of medieval interior decoration, and the exterior funerary tablet, dating from the early years of the 17th century, is a reminder that the church was also the scene of mourning for the local nobility. But it is perhaps under the plasterwork of the north wall - which is not very well pierced and is protected from the elements - that the most unsuspected treasures are hidden: mural paintings whose existence has yet to be confirmed, but which the archaeological logic of the building leads us to hope for. The visit invites slow contemplation. The building doesn't try to impress by its sheer size; it seduces by the accuracy of its proportions, the ochre patina of its limestone and that special silence of old country sanctuaries that the modern world has forgotten to disturb. Photographers, lovers of medieval architecture or simple walkers in search of authenticity will find it a precious interlude, far from the beaten tourist track.
The church of Saint-Blaise belongs to the early Norman Romanesque style, the characteristics of which it expresses with exemplary sobriety. Its plan, a simplified basilica with a single nave and slightly projecting chancel, follows the common pattern of small rural parish churches in the first half of the 12th century. The walls, built of medium-grained limestone quarried in the region, have the characteristic golden hue of the Drouais region, which warms up in the low-angled morning light. The western portal, the centrepiece of the building, features a decorative programme of several concentric voussoirs decorated with geometric and perhaps figurative motifs, whose state of preservation still suggests their original quality. The archivolt windows on the sides of the nave and choir are a perfect illustration of the transition from a Romanesque style that was still archaic to the quest for luminous clarity that characterised the following decades. The north wall, which has few openings, is both a formal curiosity - rare in architecture from this period - and a major archaeological argument for the possible conservation of wall paintings under the plaster. Inside, the painted roof frame deserves particular attention: a rare vestige of the polychrome decoration that enlivened medieval naves, it bears witness to a practice that has largely disappeared from the French countryside. The outer funerary tablet, dating from the early years of the 17th century, forms a painted belt around the outside of the walls, enhanced by armorial bearings in colours that are still legible, a touching reminder of the funerary customs of the rural nobility under Henry IV and Louis XIII.
