Archaeologists digging at Grand, a Gallo-Roman town in the Vosges of northeastern France, have recovered more than 1,000 Roman bone dice, a haul the excavation’s leader, Thierry Dechezleprêtre, has called completely unprecedented. Hundreds of them lay around a single small building, 4.5 by 3.8 meters, beside an east-west road, and three more were set into its foundations.
Nobody has settled what the building was for. The leading readings are a dice workshop, a place to play, and a shrine where dice were offered to the gods.
From 500 dice in July to more than 1,000
The count grew as the dig and the cataloguing went on. Info.fr reported on July 20 and 21, 2026 that more than 500 bone dice had been found in the Vosges that month, at the end of a season led by Dechezleprêtre, chief curator at the Musée d’Archéologie nationale in Saint-Germain-en-Laye. About fifteen archaeology students from several French universities took part, and the Conseil départemental des Vosges organized the work with funding from the Ministry of Culture through the regional DRAC Grand Est. The season followed digs in 2022, 2023 and 2024, begun to reassess structures first investigated in the 1960s, and the site stayed open to visitors until July 30 before reopening for European Heritage Days on Sept. 19 and 20.
By Aug. 3, the Spanish outlet Merca2 was putting the total at more than 1,000, describing it as the largest known collection of Roman dice. It cites the French magazine Historia for Dechezleprêtre’s comments, including that everything points to a context of devotion, and notes that University of Lorraine student Doriane Blaise is extending a catalogue of the dice that began in her master’s work.
On Oct. 7, Arkeonews carried the 1,000-plus figure in its headline, and Greek Reporter followed a day later. Both name no individual excavator. Work returned to the site in 2022; the building was exposed in 2023 and 2024.
The 4.5 by 3.8 meter building beside the road
Arkeonews describes a small structure opening east, with red-painted plaster above a yellow base. Around it lay shoe nails, pottery fragments, animal bones, brooches, bronze coins, eyed needles and hundreds of bone dice. Three dice came directly from the foundations, which Info.fr reads as a sign of a strong link to the building’s function. Its description of the structure matches Arkeonews: a small annex of the same dimensions whose exact function it calls enigmatic.
Roughly 20 meters north, a narrow water conduit with iron collars, probably for wooden pipes, was uncovered, along with a rectangular pit that may have held a wooden basin. Merca2 places most of the dice around a 2nd-century ceremonial pool in one of two small rectangular buildings it describes as chapels, with others near altars and many inside or beside jars, cups and pots.
The distinction matters for the arithmetic. The total of more than 1,000 belongs to the excavated area near the basilica and the main street, where the pool, the chapels and the altars sit; the roadside building accounts for hundreds within it. No source read for this report gives a separate count for the building alone, and the July figure of more than 500 was reported before the later total.
Workshop, game room or offering
The dice are bone, marked with concentric circles cut with a fine metal tool and possibly darkened with wax and charcoal, in the “sevens” layout where opposite faces add to seven. A Demotivateur article notes that a typical Gallo-Roman dig yields perhaps 10 to 15, and quotes the departmental council calling the 500-plus collection the largest of playing dice ever found from Antiquity.
The same article says it remains hard to favor one explanation among a dice workshop, a sanctuary or a game space under divine protection. Merca2 adds that many dice carry no visible markings, probably because paint has worn away, though some may have been offered blank, and that coins from the area often show Fortuna, goddess of luck. Dechezleprêtre is reported to see divination, gambling or both, with the line between them hard to draw.
Greek Reporter closes with a caution that the evidence does not show Grand was a Roman gambling center, which tempers the “ancient Las Vegas” label Arkeonews gave the story. The town did have scale: Arkeonews puts Roman Grand at more than 70 hectares, with an amphitheater about 148 meters long that held more than 17,000 spectators, a basilica mosaic of over 220 square meters, and a sanctuary of the healing god Apollo Grannus.
Merca2 reports that the research program runs until 2027, and the catalogue of the dice is still being extended. Until that work is published, the question of whether a workshop, a game room or a shrine stood beside that road rests on hypotheses from the excavation team and the departmental council, not on a finished study.
