Nestling in the hamlet of Saint-Martin-de-Vertou, on the outskirts of Châtillon-sur-Indre, the Maison du Bailli is one of those discreet buildings that encapsulate several centuries of monastic and seigneurial history in southern Touraine. At first glance, its simple massing - a rectangular building with two gables - suggests a functional architecture, that of a country priory designed to administer the lands of a powerful abbey. But the attentive eye soon discovers the refinements introduced by successive monks and clerics. What makes this monument unique is precisely the superimposition of its temporal strata. The five-sided stair turret attached to the east facade is a relatively rare architectural feature for a priory outbuilding of this size in Berry: its polygonal shape, carefully crafted, bears witness to an aesthetic concern that goes beyond mere utilitarian necessity. It is reminiscent of the noble manor houses that flourished in the Indre valley at the same time, at the turn of the 15th and 16th centuries. Inside, a room on the first floor preserves the remains of wall paintings with plant motifs - scrolls, stylised foliage - probably dating from the 16th or early 17th century. Fragile and incomplete, these painted decorations are nonetheless of great documentary value: they are a reminder that this building was not just a place for agricultural management, but also a living space where a certain idea of beauty was cultivated. The surrounding area adds to the quality of the experience. The quiet, unspoilt hamlet of Saint-Martin-de-Vertou offers a typical Indrean bocage setting of gentle meadows and wooded horizons. For visitors with a passion for medieval architecture or monastic heritage, this stopover is an ideal complement to a visit to the castle of Châtillon-sur-Indre, whose medieval remains are just a few kilometres away.
The Bailiff's House is a rectangular building with two gables, with a sobriety typical of 15th-century prioral architecture in Berry. The volumes are solid and functional, with no excessive projections, in the tradition of rural monastic buildings that had to combine solidity, practicality and discretion. The materials used are those of the region: local limestone, lightly gilded depending on exposure, and probably flat tiles or slate for the roof, in accordance with the customs of southern Touraine and northern Berry. The most striking architectural feature is the five-sided stair turret attached to the east facade. This type of polygonal turret, which serves the upper floors via a spiral staircase, is a distinctive feature of late medieval and early Renaissance civil and monastic architecture in the Indre valley. Its pentagonal shape gives it a strong presence on the façade and a visual lightness that a square tower would not have had. It is both an element of prestige and a practical device. Inside, the first floor contains a painted decoration of great documentary quality: murals with plant motifs - probably foliage scrolls, interlacing foliage or floral friezes - dating from the 16th or 17th century. Although only partial, these remains illustrate the spread of Renaissance decorative styles to secondary buildings in the Loire Valley, and bear witness to the care taken to furnish the interior of this prioral residence.
