The "Tours" at the beginning of the Henri IV bridge in Châtellerault are indeed a historic complex linked to the city's old fortifications. However, they must be distinguished from the three brick towers of the former Weapons Factory. The towers are located at the end of the Henri IV bridge, on the town side, and are a remnant of the defensive system that protected the crossing of the Vienne. Two round towers remain, on the Châteauneuf side. They once framed a monumental central pavilion, which may explain the name or the impression of a set of three towers. 🏰 The history of the Henri IV bridge towers 1. Towers already existed before the current bridge The crossing of the Vienne at Châtellerault is very old. In the Middle Ages, the bridge had a major strategic and economic function. At the end of the 15th century, a document already mentions two towers built on the Châteauneuf side and connected by a vault or a central structure. They were preceded by a drawbridge. It was therefore a true monumental gate giving access to the bridge. 🏛️ But there was much more than the two current towers This is probably the point that interests us. Originally, the entrance to the bridge on the Châteauneuf side comprised: - a round tower to the north; - a round tower to the south; between them, a central pavilion with - a monumental gate; - and a drawbridge allowing access to be closed. The central pavilion was demolished in 1824. The two towers, however, were preserved. Recent archaeological research has indeed made it possible to find the foundations of the central pavilion. 🔎 And there were also two other towers! The bridge was designed in a much more monumental way than we see today. At the other end of the bridge, on the town side, there were also two square towers. They disappeared later, notably because they hindered traffic. So originally there were four towers, two at each end, to which the central pavilion on the Châteauneuf side was added. 📷 A particularly interesting old photograph The Ministry of Culture holds an old photograph titled "Tour d’entrée" (Entrance Tower), taken by Georges-Louis Arlaud (1869-1944). It shows the complex at a time when both towers still existed with their ancient appearance.

They belong to the City of Châtellerault, while the bridge itself is under the jurisdiction of the Department of Vienne. Interesting point: contrary to what their military appearance might suggest, these towers did not primarily have a military defense function. They were notably used for controlling entrances and, at certain periods, for sanitary control or the collection of passage tolls.

🏭 1. A museum set up in the former “Manu” Le Grand Atelier - Museum of Art and Industry is located on the site of the former Châtellerault Arms Factory ("Manufacture d’armes"). The Manufacture was created by royal ordinance on July 14, 1819, under Louis XVIII. Construction began in 1820. Its location in Châtellerault was notably due to the presence of the Vienne river, which allowed for the use of hydraulic energy, and the existence of a significant local tradition of cutlery and metallurgy. Initially, it mainly produced edged weapons: sabers, swords, lances, and cuirasses. From the 1830s onwards, production also turned to firearms. The Manufacture gradually became a huge industrial complex, employing several thousand people. It played a considerable role in the economic and social history of Châtellerault. 🔧 2. The museum building The building now occupied by the Grand Atelier is particularly interesting. It is part of the former assembly and finishing workshop, built between 1886 and 1887, notably in the context of the production of the Lebel rifle. It is a characteristic industrial building from the late 19th century, with vast spaces, large glass bays, and saw-tooth roofs allowing for significant natural light. It is now protected as heritage. The Manufacture closed permanently in 1968. 🚗 3. The birth of the automobile museum After the closure of the Manufacture, part of the buildings was reused for cultural purposes. As early as 1969, the site hosted a museum, notably stemming from Bernard de Lassée's vehicle collection. It was first named Musée de la Technique et de l’Automobile, then became Musée Auto-Moto-Vélo. The town of Châtellerault acquired part of Bernard de Lassée's collection and gradually developed the museum. The collections include, in particular, vintage cars, motorcycles, bicycles, engines, posters, and accessories, featuring prestigious brands such as Panhard-Levassor, Delahaye, Talbot, Darracq, or Bugatti. 🏛️ 4. The merger with the former Sully museum This is an important step in understanding why the museum today bears the name “museum of art and industry”. Châtellerault also had another museum, located in the Hôtel Sully, dedicated to the history and heritage of the town: archaeology, fine arts, weapons, cutlery, ethnology, local artists, etc. Gradually, the collections of the two institutions were brought together on the site of the former Manufacture. The Ministry of Culture thus indicates that the collections were regrouped on the Manufacture site, first under the name Musée de la technique et de l’automobile, then Musée Auto-Moto-Vélo, and finally Grand Atelier. 🎭 5. The transformation into “Grand Atelier” After significant renovations, the museum was reorganized and took its current name in 2019: Le Grand Atelier – Musée d’art et d’industrie. It is therefore no longer just a museum dedicated to automobiles. It now offers three main tours: 🚗 Auto-Moto-Vélo: the evolution of transport from the 19th century to the 2000s; 🔫 Manufacture d’armes: the industrial and social history of the “Manu” and its workers; 🎭 Cabaret du Chat Noir: dedicated to Rodolphe Salis, born in Châtellerault and founder of the famous Montmartre cabaret. The museum now covers over 3,000 m² of exhibition space. An important clarification It is therefore necessary to distinguish: - The Arms Factory (“La Manufacture d’armes”) → the large industrial site created in 1819, closed in 1968. - The Grand Atelier building → a former workshop of the Manufacture, built in 1886-1887. - Le Grand Atelier – Museum of Art and Industry → the museum gradually created on this site, whose current name dates from 2019. - And the former Sully museum → a historic museum institution in Châtellerault, part of whose collections have been integrated into the Grand Atelier.

The history of the Châtellerault dam on the Vienne river, located at the site of the former weapons factory (Manufacture d’armes), is particularly interesting as it is directly linked to the industrialization of the town. 1. A first dam for the Manufacture The first structure was built around 1824, shortly after the creation of the Châtellerault weapons factory in 1819-1822. Its primary objective was not to produce electricity: it was to provide hydraulic power to the Manufacture and to regulate the level of the Vienne necessary for its installations. Administrative sources do indicate a dam built in 1824, intended to supply the Manufacture. The presence of this dam is therefore closely linked to the spectacular industrial development of Châtellerault in the 19th century. 2. The dam then plays a role in water supply The dam also gained importance for the town's water supply. After 1864, when the Manufacture no longer opposed the use of the Vienne's water, the town installed a pumping station near the dam. Hydraulic rams and then, from 1879, a steam engine, made it possible to pump water to the reservoirs and fountains of Châtellerault. It is therefore a site where three stories intersect: - the weapons factory; - water supply; - and then electricity production. 3. Transformation into a hydroelectric power plant The major turning point occurred at the beginning of the 20th century. A hydroelectric power plant was built from 1918 and commissioned in 1921, for the Société des Forces Motrices de la Vienne. The associated dam measures approximately 207 m and creates a head of 11.50 m. The power reached about 10,000 hp in 1926. There are also plans preserved at the Defence Historical Service (Service historique de la Défense) concerning precisely the dam, the spillway, the gates, and the hydroelectric power plant, dated notably from 1916 to 1928. 4. Destruction in 1944 The dam and hydroelectric installations were destroyed in 1944, during the fighting and the withdrawal of German forces. They were then rebuilt in 1952. This reconstruction partly explains why the structure we see today does not exactly correspond to the dam of the 1920s. 5. Since 1967: EDF In 1967, EDF took over the operation of the hydraulic power plant. Since then, the dam has mainly served the function of hydroelectric power production. A point of interest: this dam is not a flood control structure Despite its presence on the Vienne, it should not be equated with a large dam intended to protect Châtellerault against floods. Its storage capacity is relatively small and its role is essentially linked to electricity production and maintaining a water level. PPRI (Flood Risk Prevention Plan) documents specify that its influence is negligible during very large floods, such as those of 1913 or 1944. Simplified chronology -1824: Construction of the first dam for the Manufacture -1864-1879: Use for the water supply of Châtellerault -1918: Start of construction of the hydroelectric power plant -1920-1921: Commissioning of the hydroelectric installation -1926: power of approximately 10,000 hp -1944: The history of the Châtellerault dam on the Vienne river, located at the site of the former weapons factory, is particularly interesting as it is directly linked to the industrialization of the town.
