Archaeologists Uncover 16th-Century Gallows Site in Grenoble Linked to Protestant Rebellion
GRENOBLE, France — A chilling reminder of the turbulent religious conflicts that roiled 16th-century Europe has emerged from beneath the soil of southeastern France. Archaeologists working in the city of Grenoble have unearthed a rare gallows site dating back to the Protestant Reformation, where rebels opposing royal authority were executed and publicly displayed as a warning to others.
The discovery, made in 2024 but only announced late last year, was conducted by France’s national institution for preventive archaeology, Inrap. The team was excavating ahead of redevelopment on the city’s Esplanade when they uncovered a square masonry structure with eight stone pillars, a design indicating royal jurisdiction rather than local feudal control. This gallows complex, dating as early as 1544, was used to execute and exhibit prisoners, many of whom were Protestant rebels challenging the crown during the Reformation.
Among the 32 individuals buried in ten pits near the gallows, archaeologists identified notable figures such as Benoît Croyet, accused in 1573 of participating in an attack on Grenoble, and Charles du Puy Montbrun, a Huguenot leader who was beheaded and displayed at the site in 1575. The graves contained mostly men, with a few women, often interred in groups ranging from two to eight.
Initially, the structure was mistaken for a religious building, but further investigation revealed its grim purpose as a place of execution and post-mortem display. Nicolas Minvielle-Larousse, a researcher with Inrap, explained that medieval gallows sites are rare finds in France. He noted that the Grenoble gallows’ square plan and eight pillars reflect its high status within the kingdom’s criminal justice hierarchy, administered by the Parliament of the Dauphiné region.
This discovery provides a stark window into the harsh realities of royal justice during a period marked by violent religious strife. The Protestant Reformation, which swept across Europe in the 16th century, led to widespread conflict between Catholic monarchies and Protestant factions, with France enduring a particularly bloody series of wars and uprisings.
The site’s royal affiliation distinguishes it from more common feudal gallows, underscoring the crown’s direct involvement in suppressing dissent. Such executions were not only punitive but also served as public spectacles intended to deter rebellion.
Similar gallows sites have been documented elsewhere in Europe, but the Grenoble find stands out for its preservation and the detailed historical context it provides. The National Park Service’s archaeology program highlights the importance of such sites in understanding the social and political mechanisms of past societies.
As redevelopment plans continue, archaeologists are working to preserve the site and its findings, which contribute valuable insights into the intersection of justice, religion, and power during one of France’s most volatile eras. The discovery also complements other recent archaeological revelations, such as the uncovering of ancient villages and artifacts that illuminate the complexities of historical life in the region.
For those interested in the broader historical framework, the National Archives provides extensive resources on the Reformation’s impact across Europe, including France’s internal conflicts. Meanwhile, the Library of Congress offers a rich collection of maps and documents contextualizing the era’s religious and political upheavals.
The Grenoble gallows site stands as a poignant testament to the severe measures employed by monarchies to maintain control and the enduring scars left by religious wars that shaped modern Europe.
