Renovation work on government buildings in the Belgian coastal town of Nieuwpoort has come to a sudden halt following a series of significant archaeological finds. What began as a routine construction project has transformed into a deep dive into centuries of military history, revealing both medieval stone weaponry and unexploded ordnance from the First World War.

A Medieval Arsenal Under the Streets

The most striking discovery involves dozens of carefully crafted stone cannonballs dating back as far as the 14th century. Found near the site of what was once the city’s southern fortification wall, the sheer volume and organized nature of the find suggest something more significant than mere debris.

Archaeologists believe they have uncovered an intentional ammunition stockpile —a dedicated depot used to defend the town. The location of the find, situated near the historic Stadshalle (civic center) and the local belfry, reinforces the theory that this was a strategic military hub.

Why these artifacts matter

The discovery of these stone balls provides a window into a critical transitional era of warfare (roughly 1350–1600). During this period, projectile technology was evolving rapidly:
Versatility: These projectiles could be launched via traditional mechanical engines like trebuchets and catapults, or fired from early explosive cannons.
Specialization: The varying sizes of the recovered cannonballs suggest the town maintained a “mixed arsenal,” prepared to supply different types of weaponry depending on the siege requirements.

From Medieval Siege to Modern Warfare

As archaeologists dug deeper into more recent soil layers, the timeline of Nieuwpoort’s military importance shifted from the Middle Ages to the industrial scale of the 20th century.

Experts recovered an unexploded artillery shell from World War I. While the artifact posed a significant safety risk, it was successfully neutralized and removed by Belgium’s explosive ordnance disposal teams.

This find highlights a grim historical pattern: Nieuwpoort’s geographic position near the English Channel has made it a perennial target in European conflicts. During WWI, the town served as a frontline city, enduring heavy combat and widespread destruction.

A City Defined by its Strategic Location

The excavation has underscored the reality that in Nieuwpoort, history is a physical presence just beneath the surface. Local officials have noted that the site has exceeded all archaeological expectations, revealing a continuous thread of military readiness that spans centuries.

“These excavations confirm that every construction phase in Nieuwpoort is also a journey of discovery into our own history,” noted Ann Gheeraert, the town’s Heritage Alderman.

Conclusion
The discovery of both medieval stockpiles and WWI munitions serves as a powerful reminder of Nieuwpoort’s enduring role as a strategic military outpost. These finds transform a simple construction site into a profound historical record of how warfare has evolved over the last 700 years.
