A real-life Asterix the Gaul-style ritual site that hosted sacred ceremonies for nearly 500 years has been uncovered by archaeologists.
The ancient complex was used for religious gatherings by elite Romans and, before them, members of the Gaulish population.
The extensive Gallo-Roman sanctuary sat on a prominent hilltop overlooking the surrounding countryside.

Experts believe its dramatic location was deliberately chosen so the sacred site could be seen from miles away.
The discovery was made at Mancey, near Tournus in Burgundy, France.
The site is reminiscent of the famous Asterix comic series about a small Gaulish village that resists the armies of Julius Caesar with the help of a magical strength potion.
The beloved series has been adapted into 18 films, 15 board games, 40 video games and even its own theme park.
For centuries, the newly discovered ritual complex had remained hidden beneath dense woodland.
But surveys carried out in 2020 revealed a series of mysterious stone mounds scattered across the forest floor, as reported by Need To Know.
Archaeologists soon realised the formations were not natural but the collapsed remains of ancient structures.
Further investigation revealed six large stone mounds along with a long linear mound believed to mark the boundary wall of the sacred enclosure.
The layout of the structures, combined with large numbers of artefacts found on the surface, indicated the site was not a simple rural settlement but a significant religious complex.
More extensive studies carried out in 2025, including metal detector surveys and soil chemistry analysis, uncovered further evidence of activity.
Researchers found large numbers of Roman shoe nails across the area, suggesting the sanctuary was frequently visited and likely hosted large gatherings of worshippers.
One of the two main buildings uncovered at the site is a rectangular temple made up of a sacred hall with a vestibule at its entrance.
Archaeologists identified four main phases in the temple’s history.
The earliest stage dates back to the late third century AD, when the first clay floor was installed.
During the 2025 excavations, researchers discovered a foundation deposit beneath this floor containing 17 late Roman coins, including a gold coin issued by Emperor Tetricus I.
Around AD 325, the temple underwent major renovations.
The floor was raised, a vestibule was added and benches were built along the walls, including a raised platform believed to have served as a cult podium.
Here, archaeologists uncovered a remarkable layer containing around 10,000 remains linked to ritual banquets.
The finds included bones from suckling pigs, chickens, small birds and fish, along with fragments of ceramic and glass cups, burned coins, jewellery, beads and numerous metal and bone pins.
The discoveries suggest worshippers gathered inside the temple for ceremonial feasts and offerings.
The quality of the objects indicates that those attending the rituals likely belonged to a high-status group, leading experts to believe the sanctuary may have served as an exclusive cult site for the region’s elite.
The final chapter in the temple’s history ended dramatically in the late fourth century.
Even after the building was dismantled and looted, ritual activity continued among its ruins.
One of the most striking discoveries from this phase was a painted altar block depicting the Celtic god Sucellus, a deity associated with agriculture, forests and prosperity.
It is the only known representation of its kind.
Archaeologists also found evidence that people continued to gather at the ruined temple for ritual feasts.
A hearth had been built among the debris, surrounded by animal bones, coins and fragments of drinking vessels, suggesting a final ceremonial meal took place inside the remains of the sacred building.
The second major structure uncovered at Mancey is a classic Gallo-Roman temple known as a fanum.
The square building featured a central sacred chamber, known as a cella, surrounded by a gallery.
Excavations uncovered thousands of fragments of painted wall plaster, indicating that the temple was once richly decorated.
Researchers also discovered around 400 fragments of limestone statues near the entrance, representing at least three sculptures that were deliberately smashed after the temple was abandoned.
Evidence from the excavations suggests the sanctuary’s origins may date back even earlier than the Roman period.
Ceramic fragments from the late Iron Age indicate the site was already being visited during the La Tène cultural horizon.
From that point onwards, the sanctuary appears to have remained active for almost five centuries.
Even after the temples collapsed in the late fourth century, worshippers continued to leave coins and offerings among the ruins.
Experts say the discoveries at Mancey are offering rare insight into how ritual landscapes evolved in Roman Gaul over hundreds of years
