Ancien mur d'enceinte de la ville, located in Blois (Loir-et-Cher), is a medieval landmark built in the Middle Ages. The monument is currently closed to visitors.
A medieval vestige buried deep in the heart of Blois, the Tour Beauvoir has been standing on its rubble stone walls since the 12th century. A former seigniorial keep that became a prison until 1945, it embodies nine centuries of judicial and defensive history.

Nestling in the grounds of the former Cordeliers convent, the Tour Beauvoir is one of the oldest and most discreet architectural landmarks in the town of Blois. Far from the splendour of the royal castle that dominates the city, this massive medieval rubble stone construction speaks a more austere and crude language - that of feudal power, countal justice and confinement. What makes this monument truly unique is the density of its history: in a single building with an almost square floor plan, the heritage of a vanished seigniorial lineage is superimposed on the successive functions of defensive keep, seat of justice, medieval and then contemporary prison. The Tour Beauvoir is not a monument to be contemplated from afar - it is a monument to be felt, whose thick walls seem to preserve the memory of all those who were held captive there for nearly seven centuries. A visit here is like plunging into the depths of time. Each level, accessed by a staircase added later, reveals a single, sober, almost bare room - a pared-down style that was precisely the hallmark of medieval prison architecture. Here and there, the walls still bear the traces of forgotten lives: graffiti, nicks, the stigmata of prolonged occupation. The surrounding environment adds an extra dimension to the visit: the buildings of the former Cordeliers convent, converted into a prison in 1806, envelop the tower in a special atmosphere, halfway between monastic contemplation and prison rigour. Just a stone's throw from Blois's bustling city centre, this complex is a timeless place to stop for those seeking to touch the living fabric of history.
The Tour Beauvoir has a roughly square plan, typical of early Romanesque and Gothic keeps in the Loire Valley. Constructed from local limestone rubble - an omnipresent material in the medieval buildings of Blois - it has a ground floor, two upper floors and an attic, all of modest height, which suggests that the building was demolished at some unspecified time, probably during one of its many functional transformations. The single-pitch, slightly sloping roof confirms this hypothesis of a higher original elevation. The interior layout is remarkably radical: each level comprises a single room, with no direct communication between floors via an internal staircase. This layout, typical of the earliest defensive keeps, where controlled access to each level was in itself a security feature, necessitated the later addition of a staircase housed in an annex building adjoining the tower. The absence of an original internal staircase is one of the building's most interesting technical features. The thick rubble stone walls bear witness to the construction techniques of the 12th-13th centuries, combining structural robustness with economy of means. Set within the buildings of the former Cordeliers convent, the building is not easily visible from the outside, which accentuates its mysterious, preserved character. The original openings, which are narrow and rare, are a reminder of the tower's dual military and prison function, which it had for almost its entire existence.
