The Genesis (1626-17th Century)

The Chilworth Gunpowder Mills were born in 1626, conceived by the East India Company to supply its forces abroad. This marked the inception of one of the earliest gunpowder mills, an industry that reigned over the region for almost three centuries. As the 17th century dawned, the management of the gunpowder works at Chilworth transitioned from the East India Company to private enterprises.

George Evelyn’s Legacy

In the first half of the 17th century, George Evelyn played a pivotal role, establishing additional mills for gunpowder production in Long Ditton, Godstone, and Wotton, all within Surrey. The Evelyn family held the exclusive rights to produce gunpowder in England for the King until 1641, when the royal monopoly system was dismantled. Subsequently, the mills evolved into a crucial supplier of gunpowder to the government.

The Wartime Takeover and Closure

During World War One, the Admiralty took control of the Chilworth works. However, as the war concluded, most Admiralty structures were razed, and in 1920, the mills shuttered their operations.
