The Tomares Treasure: A Remarkable Roman Coin Hoard Discovered in Spain

In April 2016, construction workers in Tomares, a suburb of Seville, Spain, stumbled upon an extraordinary archaeological discovery while installing electrical lines in El Zaudín public park. While operating a mechanical digger, the crew unexpectedly unearthed a vast collection of Roman coins hidden in 19 large ceramic amphorae. Buried about a meter underground, these ancient containers had remained untouched for nearly 1,700 years.

Unfortunately, 10 of the amphorae were damaged by the digger during the excavation. However, nine remained intact, still sealed, and preserved in their original state. This extraordinary hoard, weighing over 1,300 pounds (600 kg) and containing more than 50,000 bronze coins, dates from the late 3rd and early 4th centuries AD, a time of great political and economic transition within the Roman Empire.

A Glimpse into Ancient History
Each coin bore the likenesses of emperors such as Diocletian (284–305 AD) and Maximian (286–305 AD), who were pivotal figures in stabilizing the Roman Empire through economic and administrative reforms. Their reigns were marked by efforts to tackle inflation, reorganize the empire, and strengthen borders, which makes the discovery of such coins particularly significant. The coins, likely minted to pay soldiers or officials, may have been stockpiled during times of uncertainty or crisis.

An Enigma Beneath the Earth
The amphorae, traditionally used to store olive oil, wine, or grain, were repurposed to safeguard these coins. They were carefully buried with bricks and ceramic filler to prevent detection, suggesting that whoever hid them intended to retrieve the treasure at a later time. However, the purpose and owners of this enormous hoard remain unknown. Were these coins intended as an emergency reserve for military operations, or were they the hidden wealth of an individual or institution fearing theft or conflict?

This find offers a rare glimpse into the economic landscape of the later Roman Empire. The sheer quantity of coins and the deliberate act of concealment suggest that the region may have been involved in important trade routes or military logistics. Moreover, it highlights the complexities of imperial finance during a time of monetary reform.

Preservation and Public Display
After the discovery, the amphorae and coins were carefully transferred to the Archaeological Museum of Seville, where they were analyzed and preserved. The museum is working on a conservation plan to stabilize the coins, some of which were corroded after centuries underground. Experts aim to determine the full historical context and meaning behind the treasure, enhancing our understanding of Roman rule in the Iberian Peninsula.

The Tomares hoard stands as one of the most significant Roman coin finds ever discovered in Spain, offering valuable insights into a turbulent period in history. Beyond its historical value, this discovery serves as a reminder of how the past can unexpectedly resurface, buried beneath the surface, waiting to be rediscovered by chance.
