About

Roman engineers arrived within a year of Trajan's conquest of Dacia and drove galleries deep into these gold-bearing hills, importing Illyrian miners as an entire transplanted community. Waxed writing tablets left underground recorded contracts, wages, and burial-club dues from the settlement above the shafts. By 117 CE the mine was eleven years into what became a century and a half of continuous extraction.

What happened here

Work goes on underground by lamplight in shifts, and the lamp is also the clock. Galleries follow the ore, propped with timber, drained by wooden screws and bucket wheels worked by hand in stages up the shaft. Ventilation is a second shaft and a fire to draw the air. The labour is convicts, slaves and paid men working side by side on different terms, and the paid men do the skilled cutting. Above ground the ore is crushed, washed in long channels, and smelted, and the smoke kills the vegetation for miles. Mines of any size are imperial property, leased to contractors under written regulations covering shifts, drainage, bath-house charges and who may open a new gallery. Settlements grow around them fast and empty just as fast.
