About

Solva watched a strategic bend of the Danube on the Pannonian frontier, garrisoned by the thousand-strong Cohors I Ulpia Pannoniorum. More than twenty altars dedicated by that unit to Jupiter Optimus Maximus turned up reused as building rubble in a late Roman brick kiln near the fort, a haul that gives a rare, near-complete picture of the garrison's official religious life. The civilian settlement that grew up around the camp prospered enough that Hadrian granted it town status in 121 CE, a step that presumes a well-established fort and vicus already standing here by 117 CE, just a few years before that promotion.

What happened here

Five hundred men, sometimes a thousand, recruited from a province rather than from citizens, and often stationed a long way from where they were raised. Cavalry units get a bigger fort and far more stabling; the smell tells you which kind you are in before the plan does. The layout copies a legionary fortress at a quarter of the size — headquarters, commander's house, granaries, barracks, a bath house usually built outside the walls because of the fire risk. Duties are patrolling, escorting, customs, and policing rather than pitched battle. After twenty-five years a man is discharged with citizenship for himself and his children, recorded on a bronze diploma he keeps for life. A village grows outside the gate within a decade.
