Excavations near the Limes Germanicus in modern-day Bavaria have uncovered a rare Roman military industrial site dedicated to the mass production of artillery bolts. Archaeologists found hundreds of standardized iron bolt-heads for the Scorpio, a powerful torsion catapult used by the Roman legions to defend the frontier. The presence of specialized tempering vats and coal-fired forges indicates that this was a high-volume factory capable of equipping an entire legionary detachment.
The site also yielded a significant collection of military leather stamps, suggesting that the projectiles were quality-checked and cataloged before being sent to nearby border forts. Analysis of the iron suggests the ore was sourced from local Alpine mines, highlighting the self-sufficiency of the Roman military machine in the northern provinces. This discovery provides new insights into the logistical complexity of maintaining the empire's borders against Germanic tribes.
