Public slaughterhouses in France
Today, slaughterhouses are an integral part of urban organization and the food chain. Yet, their appearance is relatively recent on the scale of urban history. Their creation addressed essential issues: hygiene, safety, trade organization, and urban modernization. Through the example of the Bourges slaughterhouses, we can better understand how these establishments became a true breakthrough.
For centuries, animals were slaughtered directly in towns, in butcher shops or their immediate vicinity. Each butcher had their own slaughterhouse. This practice posed numerous problems. The streets were filled with odors, waste, and blood, creating very concerning hygiene conditions. Health risks were high, and the movement of animals in the streets could cause accidents, sometimes serious ones.
Despite several attempts at regulation dating back to the Middle Ages, these practices persisted for a long time, largely due to opposition from butchers and deeply ingrained habits. It wasn't until the early 19th century that a real decision was made. In 1808, a decree mandated the creation of public slaughterhouses outside of cities, in order to centralize operations and mitigate the associated nuisances.
Implementation was gradual. In Paris, it took nearly ten years for the first slaughterhouses to become mandatory in 1818. This new model marked a turning point: slaughter was now controlled, monitored, and governed by stricter sanitary regulations. This represented a major step forward for public health, as well as for urban planning.
Bourges's slaughterhouses
In Bourges, the creation of a public slaughterhouse addressed the same hygiene and organizational concerns as in the rest of the country. As early as 1838, the municipality decided to launch a project and organized a competition to define its plans. The project by architect Louis-Hippolyte Roger, then a member of the city council, was selected. His work was praised for the quality of its design and its adaptation to the functional constraints of the site.
Despite this early decision, the construction of the slaughterhouse was plagued by numerous delays. The project remained bogged down in administrative processes for a long time, and debates surrounding its location and proposed modifications further slowed its progress. For over twenty years, construction was postponed, halted, and then restarted, illustrating the frequent difficulties faced by major public projects in the 19th century.
Building Decree
Decree authorizing the establishment of a slaughterhouse in Bourges at the hamlet La Chappe
Decree of May 11, 1861.
Napoleon, by the Grace of God and the will of the nation, Emperor of the French, to all present and to come, greetings:
On the report of our Minister Secretary of State for the Department of Agriculture, Commerce, and Public Works;
Having considered the request made by the city of Bourges (Cher), seeking authorization to establish a public slaughterhouse with tallow rendering facilities, tripe processing facilities, and pigsties.
The deliberations of the municipal council of this city, dated April 17, 1856, May 22, 1858, February 19, and August 13, 1859.
The documents from the inquiries to which the project was submitted, and which show that it did not give rise to any objections;
Having regard to the decree of October 15, 1810, and the ordinance of January 14, 1815, concerning establishments classified as dangerous, unhealthy, or inconvenient, together with the ordinance of April 15, 1808, specifically concerning public and communal slaughterhouses;
The law of July 18, 1837, on municipal administration, and the law of July 18, 1860, which authorizes the said city to borrow the sum of three hundred thousand francs, to be allocated to the execution of the said public slaughterhouse project;
Having consulted the Public Works, Agriculture, and Commerce Section and the Interior, Public Instruction, and Religious Affairs Section of our Council of State, we have decreed and do decree the following:
Article 1st
The city of Bourges is authorized to establish a public slaughterhouse, with tallow rendering facilities, tripe processing facilities, and pigsties, at the location known as La Chappe, situated between the Auron River and the Berry Canal, and in accordance with the provisions of the plan submitted to the Town Hall on February 1, 1857, which plan shall remain annexed to this decree.
Article 2
The said city is therefore authorized to acquire the properties of Messrs. Deguéret, Paré, and Gangnand for the sum of
The sum of five thousand four hundred twenty-eight francs and thirteen centimes, and subject to the terms and conditions set forth in the preliminary sales agreement of August 13, 1859, for several parcels of land located at the place called La Chappe, with an area of approximately thirty ares and fifteen hundred centimes, to be used to regularize the site on which the said slaughterhouse is to be built.
Payment for this acquisition and its construction costs will be provided for by means of the loan of three hundred thousand francs that the city is authorized to contract under the law of July 18, 1860, cited below.
Article 3
The following will be collected at the said slaughterhouse: as a site fee.
For slaughtered oxen, cows, calves, sheep, ewes, goats, pigs, and sows, the tax is 0.02 francs per kilogram of net meat.
For the cooking of beef and cow offal, the tax is 0.50 francs per kilogram.
For the cooking of veal, mutton, and ewe offal, the tax is 0.05 francs per kilogram.
For rendering tallow, the tax is 5 centimes per kilogram.
The weight of the meat for tax collection will be established according to the indications contained in the draft tariff attached to the hasty deliberation of the municipal council of February 19, 1859, namely:
Oxen and cows: 60 percent of their net live weight; calves: 65 percent; sheep and ewes: 50 percent; pigs: 75 percent.
This tariff will be revised and reduced as soon as the tax revenue has covered the reimbursement.
of the loan of three hundred thousand francs, and, at the latest, by the end of the nineteenth year following its implementation.
Article 4
The commissioning of the public slaughterhouse in Bourges will automatically entail the closure of private slaughterhouses in the town. However, residents who raise pigs for their own consumption may still have them slaughtered on their premises, provided that this is done in a building separate from the public thoroughfare.
Article 5
This authorization is granted subject to the right of the administration to collect and carry out, at any time, any measures and works it deems necessary in the interest of public health.
Article 6
Our Minister Secretary of State for the Department of Agriculture, Commerce, and Public Works and our Minister Secretary of State for the Department of the Interior are each responsible, within their respective jurisdictions, for the implementation of this decree.

First stone
When work finally began, significant technical constraints were encountered. The chosen site, located in a wetland area, was unstable and waterlogged. Deep excavation, sometimes several meters, was necessary to reach a sufficiently solid layer. The foundations, constructed with carefully fitted stones, demonstrate remarkable skill and a determination to ensure the structure's stability despite the difficulties.
Bourges perfectly illustrates this evolution: a project that took a long time to complete, faced with technical and political obstacles, but which ultimately gave rise to a modern and structuring facility for the city. Even if these buildings may seem ordinary today, they represented genuine progress in their time… and profoundly changed the daily lives of the inhabitants.
Bourges in the modern times
The Bourges slaughterhouse was designed according to modern principles for its time. Located away from residential areas and near a water source, it allowed for regular cleaning and minimized disruption. The buildings were laid out to separate the different functions: animal housing, slaughtering, and by-product processing.
This facility served several purposes. First, it improved hygiene by eliminating the scattered slaughterhouses throughout the city. It also enhanced safety by preventing animals from roaming the streets. Finally, it allowed for better control of meat quality through daily monitoring.
Beyond these practical aspects, the slaughterhouse also contributes to urban development. Its establishment transforms the neighborhood, fosters trade, and is accompanied by new infrastructure, such as livestock markets and improved traffic flow.
The creation of public slaughterhouses in France marks a significant milestone in the history of cities. It reflects a growing awareness of public health issues and a desire to better organize urban space.
After several interruptions and restarts, the construction was finally completed. The slaughterhouse was inaugurated in 1864 during an official ceremony marking the culmination of a project long awaited by the community. The building was then presented as a model establishment, both for the quality of its facilities, the solidity of its construction, and a certain architectural elegance, proof that importance was also attached to the visual aspect of this type of facility.
What remains
Les anciens abattoirs de Bourges
Throughout its history, the Prado public slaughterhouse complex underwent expansions and modernizations: new scalding and roasting rooms, two leather sheds, a horse slaughterhouse, freezers, and a municipal garage.
Surviving a fire in 1900 that ravaged the Bergerie Droite (Right Sheepfold), the slaughterhouses were finally closed in 1975, relocated to Avenue de la Prospective, and demolished in 1981. This gave way to the "New Prado": an Ibis hotel, a Leclerc shopping center, a pharmacy, 200 apartments, and a parking lot.
Research and technology at the service of history
This digital mediation project on the former slaughterhouses of Bourges, conceived, produced and distributed by Gabin FAUCARD under the brand The Past Was In Colours, is based on plans, images, descriptions, testimonies and comparative studies of other nearby public slaughterhouses.
This version of the project represents an interpretation based on the plans and drawings of architect Louis-Hippolyte Roger, prior to the actual construction of the slaughterhouses. Other stages and events in the complex's history will be available in a future version of the project.
To reconstruct the entire former slaughterhouse complex, each building was modeled in 3D using 3ds Max software.
This step involves digitally recreating the volumes, shapes, and architectural details from plans and drawings available in the archives. The goal is to reproduce the appearance and proportions of each building while respecting its historical authenticity. However, smartphones have limited resources, so it is essential to optimize each model to ensure a smooth experience. This means reducing the polygon count, simplifying the geometry while maintaining a realistic appearance.
Once the modeling is complete, the crucial step of texturing begins, adding color, depth, and realism to the surfaces. The technique used here is called triplanar mapping, a method of automatically applying textures to 3D volumes. Unlike traditional texturing, which requires complex surface unwrapping (UV mapping), triplanar projection projects the texture from three directions (X, Y, and Z), thus avoiding distortions and visible seams. This process allows for homogeneous and realistic rendering, even on irregular shapes such as towers, roofs, or sculpted stone, while reducing production time and technical constraints.
These 3D models are then integrated into Unity and incorporated into the interface designed and adapted for this project.
Scalding rooms
Scalding rooms are technical spaces where carcasses, particularly pig carcasses, are immersed in hot water to facilitate the removal of bristles. This essential step, governed by precise rules, illustrates the evolution towards more efficient and hygienic practices.
Melting pots
The rendering rooms and the tripe processing area are dedicated to the transformation of fats and the preparation of offal. These spaces illustrate the complete valorization of the animal, essential to the economy and the supply of meat products.
Tollgate
The tollgate marks the entrance to the public slaughterhouse, on the border between the city and the industrial area. Animals are declared, inspected, and counted here before being admitted, while slaughter-related taxes are collected. Serving as both an administrative and sanitary station, it manages the flow of animals and ensures the site's hygiene.
Stables
The stables and barns housed the horses of the butchers and employees. Essential for transporting meat, they ensured the mobility and efficiency of the slaughterhouse's activities, illustrating the central role of animal traction in the city.
Sheepfolds
The cattle pen and sheepfold house cattle and sheep before slaughter. They allow the animals to be organized, to rest after transport and to prepare for handling, with a view to managing flows and sanitary quality.
Livestock market
The livestock market is a place of exchange where breeders, traders and butchers buy and sell animals. Located near the slaughterhouse, it facilitates supply, reduces travel and contributes to sanitary organization.

Beyond the blueprints
Water and sanitation systems
One of the essential elements for the operation of the slaughterhouse is water. The site is designed to allow for constant cleaning of the areas, thanks to a network of pipes and taps ensuring rapid and abundant distribution.
The slightly sloping floors facilitate the flow of liquids towards drainage systems. This focus on sanitation demonstrates how central hygiene has become to the design of this type of facility.
Technical equipment for slaughtering
The internal facilities are designed to make operations more efficient and controlled. The slaughter pens are equipped with restraint systems to immobilize the animals, while devices such as winches and pulleys facilitate the handling of carcasses.
All of this equipment demonstrates a commitment to streamlining the work and improving working conditions.
Circulation spaces and the organization of flows
The organization of the slaughterhouse is not limited to the buildings themselves; it also relies on precise traffic management. The main entrance, marked by a wide gate and flanked by administrative pavilions, opens onto a large central courtyard.
This space allows for the efficient distribution of the different work areas and avoids unnecessary contact between animals, workers, and products. This organizational logic reflects a well-developed approach to ensuring smooth movement within the facility.
Ancillary spaces and the valorization of by-products
The slaughterhouse is not limited to the slaughter of animals. It also includes numerous ancillary areas for processing by-products: tallow rendering plants, scalding rooms, incinerators, and waste pits.
These facilities allow for the recovery of certain materials and the management of waste, thus preventing its accumulation and the resulting nuisances.
A coherent architectural ensemble
Beyond its utilitarian function, the Bourges slaughterhouse is designed as a structured and harmonious whole. The buildings are arranged symmetrically around a clear overall plan, with overhanging roofs providing practical shelter.
This layout reflects a desire to reconcile efficiency, robustness, and aesthetics, at a time when even industrial buildings were beginning to be the subject of genuine architectural consideration.
Like if it were yesterday
Three photographs of the slaughterhouses, taken towards the end of the 19th and the beginning of the 20th century.
They have been retouched and colorized using artificial intelligence. This colorization is based on precise research and study of the materials used in the slaughterhouse complex and the city of Bourges. Even though the final work is done using a generative algorithm, allowing for a photorealistic rendering, the entire research phase is conducted traditionally. Whether it involves archival research, on-site examination, or comparative analysis with other sites, nothing is left to chance.
This is Bourges, as life might have been 120 years ago.
Exploring the past
This video presents a demonstration of the LAAB Project – The Old Bourges Slaughterhouses mobile application, which allows users to explore the slaughterhouse complex interactively in 3D.
Developed using the Unity engine and based on 3D models created in 3ds Max, the application offers a historical and immersive experience.
Thanks to points of interest and 360° before/after views, users can visualize the complex as if they were actually there.
Each building has its own 3D model in textured or grid view, along with explanations of its history and use.
By combining technology, research, and education, the LAAB project contributes to reviving the memory of forgotten French industrial heritage.
In short, an innovative application serving cultural tourism, education, and the digital promotion of French and regional history.
