A remarkable archaeological discovery has emerged from an unexpected location – the construction site of Suffolk’s Sizewell C nuclear power station. During routine drainage work, archaeologists uncovered a treasure trove of 321 silver coins dating back to the 11th century, offering a rare window into medieval England’s rich history.

The Unexpected Discovery

What began as ordinary construction work quickly transformed into an extraordinary historical moment. Oxford Cotswold Archaeology (OCA) teams were conducting standard drainage operations when they stumbled upon what appeared to be scattered bricks. However, beneath the surface lay a lead-wrapped bundle of silver coins, later nicknamed “the pasty” due to its distinctive shape. The treasure was strategically buried at the intersection of two medieval boundary lines.

The moment of discovery was particularly memorable for archaeologist Andrew Pegg, who recalled with excitement, “I was shaking when I first unearthed it. Seeing the coin edge peeking at me was stunning.”

A Glimpse into Medieval England

Royal Transitions and Economic Networks

The coin collection spans a fascinating period from 1036 to 1044, encompᴀssing the reigns of three significant monarchs: Harold I (Harold Harefoot), Harthacnut, and Edward the Confessor. This era marked a crucial transition in English history, as power shifted from Danish rule under King Cnut and his sons back to the WesSєx dynasty.

The coins themselves tell a story of medieval England’s sophisticated economic landscape. Minted across various locations including London, Thetford, Norwich, and Ipswich, they demonstrate the extensive trade networks that existed during this period.

A Wealthy Owner’s Hidden Fortune

The treasure’s value in its time was substantial – equivalent to the worth of 16 cows in the 11th century. This suggests the owner was likely a prosperous farmer or merchant who intentionally concealed their wealth, perhaps planning to retrieve it later. The fact that the coins remained undisturbed created what archaeologists now describe as an “archaeological time capsule.”

Modern Significance and Public Engagement

This extraordinary find will soon reach a wider audience through the upcoming season of Digging for Britain on BBC Two and iPlayer. Damian Leydon, site delivery director at Sizewell C, emphasized the discovery’s importance: “This project provides a rare and fascinating glimpse into Suffolk’s past, deepening our understanding of this part of Britain.”

Preserving History Amid Progress

The discovery highlights the delicate balance between modern development and historical preservation. While Sizewell C advances as a two-reactor nuclear power station, this find, along with other artifacts including WWII equipment and an Iron Age wooden axle, underscores the site’s rich historical significance.

The coins will be preserved for future generations through museum displays, offering visitors a tangible connection to England’s medieval past. This remarkable discovery not only enhances our understanding of 11th-century England but also serves as a reminder of the historical treasures that may still lie beneath our feet, waiting to be discovered.
