Standing at the eastern corner of the Loches castle walls, the Tour du Fort Saint-Ours is one of those discreet witnesses that, without ever stealing the limelight from the neighbouring royal keep, give the fortified complex its defensive coherence and historical depth. An integral part of the Saint-Louis fort - a defensive structure designed to protect the eastern flank of the royal dwelling - the tower immediately stands out with its massive cylindrical silhouette and unexpected crown: a timber-framed dome, added in the 17th century when a building was erected against its flank, giving it an architectural uniqueness that is rare in the Touraine defensive landscape. Above all, the tower offers a vivid reading of the layers of history: the medieval masonry of the 14th century rubs shoulders with the alterations of the following centuries, and the juxtaposition of the military masonry with the civilian dome bears witness to the successive conversions that the defensive works underwent when war gave way to middle-class life. The single-arch standing bridge leading to the north gate - already mentioned in 16th-century texts - is itself a valuable architectural document of the crossing practices of the period. Visiting the Tower of Fort Saint-Ours means immersing yourself in the least frequented stratum of the Loches site, far from the tourist crowds that flock to the medieval keep or the Collegiate Church of Saint-Ours. The attentive walker will discover a sober and efficient architecture of usefulness, where each stone responds to a precise defensive logic. The surviving north gate, flanked by two solid cylindrical towers, is a fine example of a fortified entrance system typical of the late Middle Ages. The setting adds to the atmosphere: the hillside of Loches, dominated by the imposing silhouette of the medieval town, places the tower in a remarkably coherent urban and landscape environment. Listed as a Historic Monument since 1968, its protection guarantees the continued existence of this defensive architecture, which bears witness to several centuries of royal and military life in Touraine.
The Tour du Fort Saint-Ours adopts the cylindrical plan characteristic of medieval flanking towers from the late 14th century. Designed as a solid tower - i.e. without hollow interior fittings in its lower section - it was a response to the defensive logic of the time: the compact masonry mass was more resistant to fire from war machines and, later, the first fire hydrants. This cylindrical shape, a departure from the square towers of previous centuries, bears witness to a significant technical evolution in the art of fortification. The upper part of the tower is the most striking and unusual architectural feature of the building: the timber-framed dome, added during the 17th-century works that coincided with the construction of the adjoining building, creates an unexpected dialogue between the medieval military heritage and the civil architecture of the classical era. This graft, far from being clumsy, gives the tower a rare architectural personality, which clearly distinguishes it from the other towers in the Loch enclosure. The fort's north gate, which the tower flanked with a sister tower that no longer exists, is the other highlight of the complex. Its entrance system - with its single-arched standing bridge, two cylindrical flanking towers and carriage entrance - is a complete and legible example of medieval fortified access. The materials used, typical of Touraine construction, probably combine local tufa stone and hard limestone, giving the whole structure that light colour so typical of the Loire Valley.
