Archaeologists discovered five pairs of iron shackles at a 2,300-year-old Celtic site in Allonnes, France, indicating the settlement served as a hub for slave trading during the Late Iron Age. According to the French National Institute for Preventive Archaeological Research (INRAP), these rare restraints provide physical evidence of a hierarchical society where prisoners of war, convicts, and debtors were enslaved by Gallic tribes.
Iron Shackles Reveal Slave Trade in Late Iron Age Gaul
The discovery at the Allonnes site in France’s Loire Valley includes a double-wrist restraint, an ankle restraint, and three other metal restraint fragments. These items are considered extremely rare for the period between 450 and 50 B.C., as the Celts left few written records of their own social structures. The ankle restraint weighed over 2.2 pounds (1 kilogram), which INRAP reports highlights the physical burden carried by enslaved people.
Thierry Lejars, a specialist in Celtic metalwork, stated in an interview with INRAP that the presence of both weapons and restraints suggests a social organization divided into dominant and subordinate groups. The small diameter of one wrist restraint—measuring 2.4 inches (6 centimeters)—suggests it was likely used on a child or woman.
Specialized Metalworking and Commercial Activity at Allonnes
The settlement was established in the third century B.C. alongside a religious complex. Excavations revealed that Allonnes was a center for high-level craftsmanship, featuring workshops for blacksmiths, coppersmiths, bronze workers, and sheet-metal workers. Beyond shackles, archaeologists recovered high-quality metal goods, including:
- Swords and spearheads
- Keys
- Horse harness fittings
The site’s location at the intersection of several major ancient roads likely facilitated its role as a commercial and trading center, making it an ideal location for the movement of both luxury goods and enslaved people.
Ritual Offerings and Mutilated Currency
Alongside the evidence of slavery, researchers found a religious sanctuary containing offerings of jewelry, rings, amulets, and clothing. Many of these items were deliberately deformed. According to the INRAP statement, this mutilation was intended to transform a common possession into a sacred gift for the gods.
Isabelle Bollard-Raineau, an ancient-coin expert with the French ministry of culture, identified hundreds of coins at the site with mint dates spanning five centuries. About one-third of these coins were etched with chisels or sheared. Bollard-Raineau explained that these modifications removed the coins’ commercial value, dedicating them to the sacred and ensuring the permanence of the offering.
Summary of Findings at Allonnes
| Category | Findings | Significance |
|---|---|---|
| Restraints | 5 pairs of iron shackles | Evidence of slave trading and social hierarchy |
| Craftsmanship | Workshops for bronze, copper, and iron | High-level industrial specialization |
| Rituals | Mutilated coins and jewelry | Sacred offerings to remove commercial value |
| Trade | Intersection of major roads | Strategic hub for regional commerce |
The Allonnes discovery fills a critical gap in the historical record of pre-Roman Gaul. By providing tangible evidence of the tools used to restrain the powerless, the site offers a rare glimpse into the lives of those typically omitted from ancient Celtic history.
