When we think of medieval castles, our minds drift to the distant past, imagining fortresses that have stood the test of time, weathering wars, conquests, and centuries of history. But what if we told you that there’s a castle whose history is still in the making, being built not centuries ago but right here in the modern era? Welcome to Guédelon Castle—a marvel that’s rewriting history one stone at a time.
Located in the heart of the Burgundy region of France, Guédelon Castle is not your typical medieval stronghold. Instead of being a relic of the past, it’s a physical demonstration of human ingenuity and dedication to bring medieval construction techniques into the 21st century. No modern tools, all traditional materials. This unique project aims to build a castle using the very techniques and materials that would have been employed in the 13th century. Intrigued yet? Let’s enter the fascinating world of Guédelon and discover what makes this ongoing project so extraordinary.
The Vision and Beginnings of Guédelon

The brainchild of Michel Guyot, a passionate historian and entrepreneur, Guédelon Castle began as an ambitious dream. Guyot, inspired by the restoration of a nearby castle, envisioned a place where history could be brought to life through the process of creation rather than restoration. His vision was to build a castle from scratch, using only the methods and materials available to medieval craftsmen.
In 1997, construction commenced on a pristine site devoid of any pre-existing structures. The chosen location, a former sandstone quarry, provided an abundant supply of the necessary building materials. The project quickly attracted a team of dedicated builders, historians, and volunteers, all eager to turn Guyot’s dream into reality.

The initial stages of the project involved meticulous planning and research. Guyot assembled a team of historians, archaeologists, architects, and craftsmen, each bringing their expertise to the table. They pored over medieval manuscripts, architectural drawings, and historical records to develop a comprehensive plan for the construction of the castle. This collaborative approach ensured that every aspect of the project adhered to the principles and practices of 13th-century castle building.
The project quickly attracted a team of dedicated builders, historians, and volunteers, all eager to turn Guyot’s dream into reality. What began as a small group of enthusiasts soon grew into a vibrant community, united by a shared passion for history and craftsmanship. The team included stonemasons, carpenters, blacksmiths, and other skilled artisans, each committed to mastering the techniques of their medieval counterparts.
Crafting a Medieval Masterpiece

The architecture of Guédelon Castle is a blend of Romanesque and early Gothic styles, reflecting the transitional period of the 13th century. The layout includes all the essential features of a medieval stronghold: a keep, curtain walls, corner towers, a great hall, and a chapel.
One of the most remarkable aspects of Guédelon is the commitment to authenticity. Builders employ traditional techniques, using only hand tools and following medieval construction methods meticulously. Every stone is cut by hand, every piece of wood hewn with axes, and lime mortar is mixed on-site. The use of these ancient techniques provides invaluable insights into the craftsmanship of the era, turning the site into a living laboratory of medieval construction.
A Journey Through Construction Techniques

The stonemasons at Guédelon use techniques documented in medieval manuscripts. Stones are quarried, shaped, and laid with precision, following the architectural plans developed by a master mason. The mortar, a crucial component, is made from local lime and sand, mixed to the exact proportions used in the medieval period.
Building a castle from scratch using only medieval techniques is no small feat. The project has faced numerous challenges, from sourcing authentic materials to overcoming technical difficulties inherent in using ancient methods. However, each obstacle has provided an opportunity for learning and innovation.
One particularly challenging aspect of the project has been the construction of the castle’s intricate stonework. Medieval stonemasons were highly skilled craftsmen, and replicating their techniques required extensive research and practice. The team at Guédelon meticulously studies historical records and surviving examples of medieval masonry, experimenting with different methods until they achieve the desired results.
Another significant challenge has been the use of traditional tools and methods. Modern construction relies heavily on machinery and technology, but at Guédelon, every task is performed by hand. This includes quarrying stone, shaping timber, and mixing mortar. The labor-intensive nature of the work has slowed progress but has also deepened the team’s appreciation for the skill and dedication of medieval builders.
Woodworkers are equally dedicated to historical accuracy. They fashion beams, joists, and planks using traditional tools like adzes and froes. The roofing of the castle is particularly impressive, with wooden shingles crafted and laid in the same manner as they would have been centuries ago.
A Living Laboratory of Medieval Techniques

Guédelon Castle serves as a living laboratory, offering invaluable insights into the techniques and daily lives of medieval craftsmen. The project’s commitment to authenticity extends to every aspect of the construction process, from the tools and materials used to the methods of organization and management.
The builders at Guédelon work under the supervision of a master mason, much like their medieval counterparts. The master mason is responsible for overseeing the entire project, ensuring that each element of the construction adheres to historical standards. This hierarchical structure mirrors the organization of medieval building sites, where apprentices and journeymen worked under the guidance of a master craftsman.
The project also emphasizes the importance of sustainability and resourcefulness, key principles of medieval construction. The team uses locally sourced materials, including sandstone from the quarry and timber from the surrounding forests. They employ traditional methods of transportation, using oxen and carts to move heavy loads. This approach not only enhances the authenticity of the project but also reduces its environmental impact.
The Drawbridge Dilemma

In the early stages of Guédelon Castle’s construction, the team faced a particularly amusing yet challenging dilemma: the drawbridge. The drawbridge is a quintessential feature of any medieval castle, providing both security and a dramatic entrance. The builders at Guédelon were determined to create an authentic drawbridge using only medieval techniques and materials.
Initially, the team designed and constructed the drawbridge based on historical blueprints and records. They meticulously crafted the wooden bridge, incorporating all the traditional elements, including a counterweight system meant to allow the bridge to be raised and lowered with ease. However, once completed, they encountered a significant problem: the drawbridge was too heavy for the counterweights to lift.
This unexpected issue led to a series of head-scratching moments and lively debates among the builders. The team had followed medieval principles to the letter, but something was clearly amiss. After several attempts to adjust the counterweights and mechanisms, they realized that the bridge’s weight distribution was not quite right. The solution required a combination of re-engineering and a bit of creative thinking.
The builders decided to lighten the bridge by modifying its design slightly, all while maintaining the historical accuracy. They also adjusted the counterweight system, ensuring it could handle the revised weight of the bridge. This process involved numerous trials and errors, with the team learning valuable lessons about medieval engineering and the importance of precision.
The Carpentry Conundrum: Building the Great Hall Roof

Another fascinating story from Guédelon involves the castle’s carpenters and their ambitious task of constructing the roof of the great hall. The great hall is one of the central features of any medieval castle, serving as a communal space for feasts, gatherings, and important ceremonies. The roof of the great hall, with its complex timber frame, posed a significant challenge for the carpenters at Guédelon.
The team of carpenters, armed only with medieval tools such as adzes, axes, and froes, set out to create a timber frame that was both sturdy and historically accurate. They began by selecting and felling trees from the surrounding forest, just as their medieval counterparts would have done. Each piece of timber was carefully hewn and shaped by hand, a labor-intensive process that required immense skill and precision.
However, the process was far from straightforward. The carpenters faced numerous trials and errors, with some joints not fitting perfectly and others needing to be reworked entirely. The challenge was not only to create a frame that was structurally sound but also to ensure it adhered to the aesthetic principles of medieval architecture.
One particularly challenging aspect was the construction of the roof’s trusses, the triangular frameworks that support the roof. The carpenters had to ensure that each truss was identical in size and shape, requiring a high degree of accuracy. The process involved lifting and positioning heavy timbers, often requiring the coordinated effort of several workers.
Despite the difficulties, the team persevered, drawing on historical records and their growing expertise. Their hard work paid off when they finally completed the timber frame, creating a stunning example of medieval carpentry. The experience not only honed their skills but also deepened their appreciation for the craftsmanship required to build such structures.
