A jewel of late Gothic architecture in the Eure-et-Loir region, the church of Saint-Lubin in Boullay-Thierry stands out for its bell tower with a pyramidal dome and hexagonal turret, fine examples of the generosity of the great seigneurial families of the 15th century.

In the heart of the peaceful village of Boullay-Thierry, in the canton of Nogent-le-Roi where the Flamboyant Gothic style left its most beautiful mark on the countryside, the parish church of Saint-Lubin stands out as a remarkable example of late medieval religious architecture. Modest in appearance, it conceals a rare architectural coherence: a single nave, a bell tower crowned with a four-sided dome, and a hexagonal turret grafted onto the projection - all signs of an ambitious commission carried out by the local aristocracy. What makes Saint-Lubin truly unique is the legibility of its history written in stone. The eaves that punctuate the tower's upper storeys, the late Gothic sculpted decorations, the seigniorial chapel that opened onto the choir in the 19th century: each element tells the story of a layer of devotion and patronage. The attentive visitor immediately grasps that this church was a place of representation as much as of prayer, at the crossroads of the sacred and local power. The experience of visiting is one of intimate discovery. Far from the crowds of the great cathedrals, Saint-Lubin invites silent contemplation. You can stroll along the unique nave in all its splendour, look up at the characteristic late Gothic ribs and linger over the sculpted details, which reveal their finesse of execution in the low autumn afternoon light. The village of Boullay-Thierry, nestling in the gentle undulations of the Beauceron plateau, is a haven of green calm. The outbuildings of the neighbouring château, to which the southern chapel once had direct access, are a reminder that this area was long organised around a structured seigneurial life. An ideal stop-off for anyone exploring the heritage routes between Chartres and Dreux.
The church of Saint-Lubin is part of a specific typology, well documented in the canton of Nogent-le-Roi: that of the single-vessel church, a formula favoured in the Dunois and Thymerais countryside at the end of the Middle Ages for its spatial clarity and relative economy of construction. This simple plan gives the interior a great deal of unity, focusing the eye on the choir and its semi-circular apse, surrounded to the north by a low corridor running around the semi-circular apse to the sacristy - a practical and discreet solution typical of late-medieval rural architecture. The most striking feature of the exterior is undoubtedly the bell tower, the upper storeys of which are punctuated by finely moulded horizontal eaves. This tower ends in a four-sided cupola, an unusual crowning feature that gives it a distinctive silhouette in the Beauce landscape. The hexagonal stair turret adjoining the tower is as much a decorative motif as a functional one, with its six-sided plan and engaged colonnettes attesting to the particular care taken in the overall composition. The architectural decorations - moulded bases, infilled windows, sculpted friezes - belong to the vocabulary of the late or flamboyant Gothic style, with its predilection for curved lines and the play of light on the stone. To the south, the seigniorial chapel added in the 19th century by the de Boquestant family introduces a measured stylistic break, pragmatically integrated into the medieval ensemble. Its direct connection with the château's outbuildings bears witness to the fact that the religious space was conceived as an extension of the seigniorial space, an ancient tradition that has been maintained here well into the past.
