In the heart of Troo, a medieval village perched on a tufa cliff overlooking the Loir, the church of Saint-Martin stands out as one of the most distinctive religious buildings in northern Loir-et-Cher. Listed as a historic monument since 1862, its walls encapsulate eight centuries of sacred architecture, from late Romanesque to flamboyant Gothic, forming a dialogue of stonework that is as coherent as it is surprising. What immediately sets Saint-Martin apart is its silhouette: a square tower set with authority on the transept crossing, a signal visible from the valley, which recalls the influence of the great collegiate churches of the Loire without slavishly copying their forms. The western doorway, flanked by columns whose capitals are adorned with Romanesque foliage and tracery, is a veritable stone book that is rarely easy to read for the attentive visitor. Inside, the Latin cross plan reveals its successive stratifications: the rigour of the Romanesque proportions gradually gives way to the vertical élans introduced in the 14th and 15th centuries, when the Gothic master builders raised the vaults and pierced new openings to flood the choir with light. The whole exudes a dignified austerity, far removed from facile picturesqueness, that will appeal to lovers of authentic architecture. The visit is a natural extension to the discovery of Troo, an exceptional village of troglodyte houses, underground passageways and terraced gardens. Saint-Martin is the spiritual and architectural centrepiece, the building around which the medieval community was organised for centuries. To stand in front of its Romanesque portal is to appreciate the continuity of a place that has been inhabited and prayed in uninterrupted fashion since the Middle Ages.
Saint-Martin's church has a Latin cross floor plan, the canonical form of medieval religious architecture, which makes the building immediately legible from the outside. The most spectacular feature is the crossing tower, set at the intersection of the nave and transept: square at the base, it rises with a certain sobriety above the roofs, dominating the village of Troo and the Loir valley. This layout - a tower over the transept rather than on the façade - is characteristic of many rural Romanesque churches in Maine and Touraine. The western portal is the masterpiece of Romanesque sculpture at Saint-Martin. Flanked by engaged columns, it features finely worked capitals whose motifs - stylised acanthus leaves, tracery and perhaps a few figures - are representative of the Romanesque ornamental repertoire of the second half of the 12th century in this region. The semi-circular arch that caps the whole reinforces the impression of a solemn entrance designed to mark the passage between the secular world and the sacred space. The materials used are those of the region: white tufa stone from the Loir valley, a soft, easy-to-work stone used for both the construction of the walls and the carving of the capitals. Inside, the Gothic campaigns of the 14th and 15th centuries can be seen in the reworked elevations, ribbed vaults and elongated bays that sit alongside the original Romanesque sections, creating the architectural palimpsest so characteristic of rural buildings built over the long term.
