Poudredrie Royale De Wetteren

Poudredrie Royale de Wetteren (Koninklijke Buskruitfabriek Cooppal) was a royal gunpowder works in the Belgian town of Wetteren, known in the local dialect as "'t Poerkot" — a nod to "poeder" or the French "poudre", meaning gunpowder. Almost two centuries of production have left behind mainly a director's residence and a castle park, but the site's history stretches back to the late 18th century and runs through several chapters of European military politics.

Who founded the factory, and when?

The works were established in 1778 by Jan Frans Cooppal (1724–1804). In the early years, other merchant families held stakes alongside him, but from 1838 onward the factory became the sole property of his successor, Pieter Frans Cooppal. Gunpowder production quickly turned Wetteren into a notable center of the region's arms industry.

How did the factory survive the Napoleonic era?

In 1796, French occupying authorities shut the plant down — a common move aimed at controlling explosives production in conquered territory. It wasn't until late 1815, after Napoleon's fall, that the newly formed United Kingdom of the Netherlands granted permission to reopen the powder works. The restart coincided with the broader rebuilding of Europe's military order in the aftermath of Waterloo.

Where does the "Royal" title come from?

In 1847, King Leopold I granted the factory the distinguished title "Koninklijke Buskruitfabriek" — Royal Gunpowder Factory. It was recognition of the company's national importance, and a mark of prestige the works carried in its name from then on.

What role did the Crimean War play in the factory's growth?

The Crimean War (1853–1856) brought the factory very large orders for war powder destined for England. To meet demand, production had to be scaled up and equipment modernized: steam engines were introduced, replacing the cart horses previously used to move materials around the site. In 1857, a second steam engine was installed, this one driving as many as sixteen powder mills at once.

What happened after the catastrophic explosion?

In 1880, the factory suffered a catastrophic explosion. In its wake, the company decided to build a new plant at Kaulille, shifting part of production away from Wetteren, though activity at the original site continued.

How did the factory's output change in the 20th century?

In 1898, Cooppal opened an ether factory across the street, broadening the business beyond traditional gunpowder. After the First World War, gunpowder was steadily displaced by newer types of explosives, forcing the company to rethink its strategy. In 1919 it was reorganized and renamed Poudreries Réunies de Belgique (PRB). In 1952, the Wetteren site began producing polyurethane foam under license from Bayer — a striking departure from its original military-industrial purpose. The Cooppal factory ultimately closed for good in 1966.

What can visitors see on site today?

Of the original industrial complex, the most notable survivor is the factory director's residence, built in 1869–70 at Cooppallaan 91, together with the surrounding castle park known as Kasteel Cooppalfabriek. This ensemble was listed as a protected monument on 3 June 2005, preserving a fragment of the old Royal Gunpowder Factory's history for residents and visitors to Wetteren alike.
