Tour d'Argent (ancien Hôtel des Monnaies des Comtes de Blois), located in Blois (Loir-et-Cher), is a Renaissance château built in the 16th century. The monument is currently closed to visitors.
A vanished vestige of the monetary power of the Counts of Blois, the Tour d'Argent embodied the medieval authority of seigneurial coinage in the heart of the Loire town, between the Gothic and Renaissance periods.

The Tour d'Argent de Blois, officially known as the former Mint of the Counts of Blois, is one of the most remarkable examples of the economic and political organisation of the Blois seigneury in the Middle Ages. Nestling in the dense urban fabric of Blois, this building combined a regal function - minting coins - with defensive architecture, as was customary for medieval mints, whose security depended on the prosperity of the Count's power. What made this monument truly unique was its dual chronological signature: a thirteenth-century foundation, at a time when the Counts of Blois were among the great feudatories of the Capetian kingdom, followed by a revival or remodelling in the fifteenth century, a pivotal moment when the town entered the royal orbit of the Valois. This superimposition, which can be read in stone, tells the story of five centuries of French history, from independent fiefdoms to the dominance of the Crown. The experience of visiting the Tour d'Argent - before it was demolished - was to offer a striking contrast with the splendour of the nearby royal castle. Where the Valois palace displayed its Renaissance magnificence, the Hôtel des Monnaies recalled the more austere, more functional foundations of medieval power: thick walls, spaces designed for surveillance and production, architecture at the service of rigorous monetary logistics. The Blois setting amplified the heritage value of this building. Blois, the gateway town between the Beauce and the Loire Valley, has been the scene of major political changes; every stone in its historic centre bears the memory of successive dynasties. The Tour d'Argent was part of this exceptional urban stratigraphy, just a stone's throw from the castle where dreams of royal grandeur were born and died. Today, the disappearance of this building - burnt down in June 1940 during the exodus and probably demolished by 1942 - makes it a ghost monument, even more precious in the collective memory and in the archives, painful testimony to the destruction of the Second World War on the heritage of the Loire.
The architecture of the Tour d'Argent was typical of the civil administrative and security buildings of the central Middle Ages. The 13th-century construction was in the primitive Gothic style for civil use: tufa limestone or hard limestone from the Loire Valley, thick walls designed to discourage any attempt to break in, and a high layout - the "tower" evoked in the popular name suggests a vertical volume dominating the surrounding land. The original openings must have been narrow and few in number, in line with the security requirements of a monetary workshop. The 15th-century alterations probably introduced elements of comfort and aesthetics specific to late flamboyant Gothic or the early influences of the Loire Renaissance: remodelling of certain bays, possible addition of dormer windows or sculpted decorations, and adaptation of interior spaces to administrative or residential functions. At the time, Blois was an exceptional architectural laboratory, and even the town's secondary buildings benefited from the modernising spirit that was simultaneously transforming the nearby royal chateau. The popular name "Tour d'Argent" (Silver Tower) - evocative of the wealth of metal that circulated there - reinforced the image of a compact, squat building, marked by its relative verticality in a single-storey urban fabric. The complete disappearance of the building in 1942 makes it impossible to specify its exact dimensions or to describe the interior layout in detail, but comparisons with medieval coin workshops preserved in France suggest a simple rectangular layout, with casting and minting workshops on the ground floor, and guard and accounting areas on the upper floors.
