A rare Cornish factory site that supplied the Royal Navy with explosives during the First World War has been given heritage protection.
The National Explosives Factory in Hayle has been given protected status on the advice of Historic England.
Initially built to supply explosives to the mining industry, the factory later produced cordite during the First World War.
At the height of production, the site employed 1800 people from the local area - mainly women.
Historic England says recognising the site acknowledges its "outstanding historic interest".
Commenting on the announcement the factory has been given heritage protection, Rob Nolan of Cornwall Council said:
“As the owners of most of the site of the Explosives Works, Cornwall Council is thrilled that the important role this site played in history has been recognised with this designation".
There are almost 400,000 items on the heritage protection list, covering England's most valued historic places.
