Nîmes: In the Footsteps of the Roman Empire
In the heart of Roman Nemausus, the thriving colony of Augustus, a shadowy conspiracy unfolded in the 1st century AD. Priests of the imperial cult, guardians of the Maison Carrée temple dedicated to the emperor's lost heirs, inscribed a cryptic code across the city's sacred sites. This cipher concealed a prophecy foretelling rebellion against Rome—knowledge so dangerous it was meant to vanish forever. But a traitorous faction stole the key tablet, sparking a chain of omens: crumbling augural towers, poisoned springs at the Fontaine de Nemausos, and whispers of divine retribution haunting the Arènes. Recent excavations on Rue Rouget de Lisle unearthed fragments of this Volque-era plot, linking protohistoric roots to Roman intrigue within a 1.5 km radius. You are the last initiate, armed with a partial cipher. Race through the amphitheater, forum remnants, Tour Magne ramparts, temple podium, museum mosaics, Porte de France arch, and theater ruins to decode the full message. Solve the priests' riddle, expose the traitors' names, and thwart the ancient curse—or Nemausus's ghosts will drag you into oblivion. The truth awaits at the final sanctuary.
« The past is not dead, it is not even past. »— William Faulkner
From Nemausus to Nîmes, a Roman epic
Nîmes, or Nemausus as it was known in antiquity, was one of the most important cities in Roman Gaul. Founded by veterans of Augustus's army around 28 BC, it quickly became a 'colony of Latin right,' enjoying considerable privileges. Its urban planning, aqueducts, amphitheater, and temples bear witness to the grandeur and sophistication of Roman engineering, making this city a major economic and cultural crossroads.
The crocodile and palm, symbols of Augustus's victory in Egypt, still adorn the city's coat of arms today, recalling its unbreakable link with the emperor and its role in the history of Nîmes. Nîmes' monuments are open books on this fascinating era, from the Arenas to the Maison Carrée, including the Tour Magne, each stone tells a part of this glorious past that forged Nîmes' heritage.
