History

In 1798, Moses Austin, a settler from Connecticut, obtained a Spanish land grant of one square league (approximately 3 square miles) of land after learning of the richness of the area's rich mineral deposits. After bringing in equipment and workmen from Virginia, he began mining and smelting lead despite frequent problems with the neighboring Osage tribe. In 1808, Austin and Samuel Hammond laid out a town at the mouth of Joachim Creek. The purpose of the new town was to serve as a shipping point for the lead smelted at mines in Jefferson and Washington Counties. It is believed the town was named by Austin, who called it Herculaneum because the limestone strata were so eroded that they resembled seats in the amphitheater of the ancient Roman city of Herculaneum buried by Mt. Vesuvius in 79 A.D.

The first post office in Jefferson County was at Herculaneum, established soon after the town was laid out, and it remained the only post office in the county for nearly thirty years.

By 1813, three shot towers had been constructed on the bluffs. These were designed for the production of shot balls by dropping molten lead through copper sieves. The balls were then caught in a water basin and taken to an adjoining building, to be turned through cylinders to round and smooth the pellets for use as projectiles in firearms.
