For decades archaeologists have exploring Egypt’s Eastern Desert, uncovering among other things the remnants of its vast ancient mining industry that functioned as an economic engine for the empire in ancient Egyptian times.
Since 1994, the French Archaeological Mission has excavated over 20 sites in the region, with a focus on Roman forts and Ptolemaic-era mines. This resource-rich landscape was heavily exploited during the Hellenistic period (332–30 BC), and recent discoveries at an ancient site known as Ghozza have provided a stark look at the brutal conditions endured by the slaves who toiled in the gold mines of ancient Egypt.
A Gold Boom in the Ptolemaic Period
Egyptian gold has long been prized, as was long found in abundance in the Eastern Desert. Mining surged during the New Kingdom (c. 1500–1000 BC) and again in the Hellenistic period, following Alexander the Great’s conquest of Egypt in 332 BC.

“The new dynasty founded by Ptolemy I needed gold to fund military campaigns in the Mediterranean, prestige projects abroad and monumental buildings in Alexandria, reflecting its power and wealth,” explained French Archaeological Mission associate Bérangère Redon, in an article about the Mission’s discoveries published by Antiquity.

The Ptolemaic rulers rapidly expanded mining operations starting in the late fourth century BC. Nearly 40 new mines were established under their rule, highlighting the greedy ambition that motivated their efforts to exploit the ancient world’s most coveted resource.
One of the earliest of the Ptolemaic gold mines, Samut North, was excavated by French archaeologists in 2014–2015. The site provided valuable insight into the gold extraction process, but appears to have been operational for only four to five seasons in the 310s BC. The workforce was tightly controlled, with at least some workers housed in guarded dormitories.
Excavations at Ghozza, the northernmost Ptolemaic gold mine, began in 2020 and uncovered two primary phases of occupation, each lasting several years in the latter half of the third century BC. Unlike Samut North, Ghozza functioned as a self-contained village, featuring residential blocks, streets, administrative structures, and even bathhouses, hinting at a different social and work environment.
The mining techniques that were used varied. While Samut North relied on collective grinding using large mills, Ghozza’s miners processed ore by hand using grinding stones. Hundreds of ostraca—pieces of pottery used for writing—found at the site suggest that some miners received wages (which would undoubtedly have been low).

The absence of fortified buildings raises questions about the nature of labor at Ghozza. Despite indications of a mixed workforce, evidence has emerged suggesting that forced labor was still present.
A Shackled Workforce, Toiling for the Kingdom
In January 2023, archaeologists unearthed iron shackles in Sector 44, an area on the village’s eastern edge. This sector, primarily used for storage and food preparation, also contained charcoal reserves and iron slag, indicating on-site metalworking.

Within these buildings, two sets of shackles were discovered. One, consisting of seven foot-rings and two linked restraints, was neatly arranged in a pit. Another set, featuring four links and two ring fragments, was found scattered across the floor of a room, amid a collection of iron artifacts.
These shackles were not designed for animals, as rope ties were typically used for livestock. Instead, they were specifically crafted to restrain human beings. Once locked around a person’s ankles, they could not be removed without the use of a key. While the hands remained free, movement would have been painfully slow and exhausting due to the weight of the restraints, which were designed to severely restrict mobility.

This find aligns with historical accounts from Agatharchides, a second-century BC writer who described the horrific conditions slaves and prisoners experienced in Ptolemaic gold mines:
"Those who have been condemned in this way—and they are of a great multitude and all have their feet bound—work at their tasks unceasingly both by day and throughout the entire night."
He identified these laborers as prisoners of war and convicted criminals, though it is likely that individuals who followed other routes into slavery could be counted among their ranks.
Shackles are rarely found in the Egyptian archaeological record. Beyond Agatharchides’ writings and a contemporaneous papyrus mentioning ‘a pair of shackles,’ physical evidence of such restraints is scarce. The Ghozza shackles rank among the oldest ever discovered in the Mediterranean, predating Late Iron Age and Roman-era shackles found in Europe.
This shouldn’t be taken as proof that slavery was relatively rare in Ptolemaic Egypt, however. It is more likely that the metal from discarded shackles was melted down or otherwise repurposed, meaning they wouldn’t be so commonly found during modern excavations.
Interestingly, the restraints found at Ghozza closely resemble depictions of fettered individuals in Greek art, and are similar to shackles unearthed in the silver mines of Laurion, Greece, in the 1870s. This connection reinforces the idea that Greek and Macedonian engineers, brought to Egypt by the Ptolemies, imported the mining technologies and labor control methods they’d relied on to get results in other places.

The Harsh Realities of Ancient Egyptian Mining
The discovery of human shackles at Ghozza provides undeniable evidence that forced labor played a role in Ptolemaic mining operations. However, the exact living conditions of these individuals remain unclear, as their dwellings have yet to be identified.
The village layout suggests that at least some of the population was free to move about, adding further complexity to the labor system that was employed in these mines. What can’t be known is if the increased intensity of gold mining operations in Ptolemaic-era Egypt required the use of slaves to supplement paid labor, or if slaves were used initially and paid laborers added to the mix later.
With over half of Ghozza still unexcavated, archaeologists hope future digs will reveal whether holding areas for slaves existed.
The discovery of the ancient shackles is certainly revealing, as it shows the high human costs behind Egypt’s legendary wealth. The gold that funded military campaigns and grand monuments came at a heavy price, extracted through the grueling work of laborers who at least in some cases were brutally exploited and forced to toil against their will, as their punishment for crimes real or imagined.
