The former National Filling Factory in Barnbow, Leeds, employed 16,000 women to produce high-explosive shells for use in the Great War.

However, the factory became the setting for tragedy in December 1916 when 35 women – known as the ‘Barnbow lasses’ – were killed in what remains the single largest loss of life in the city’s history.

Heritage minister Tracey Crouch MP said: "As we mark the centenary of the First World War, it's so important that we remember the sacrifices of those who supported on the home front – especially women.

“The Barnbow lasses played such a vital role in the war effort and by scheduling this factory, we continue to pay tribute to their contributions and sacrifices 100 years on."

The remains of the factory lie near the proposed East Leeds Orbital Road and the area of a proposed housing development.

However, Historic England claims to have had constructive discussions with Leeds County Council and partners to ensure that the newly protected site has been taken into account during planning.

Councillor Judith Blake, leader of Leeds City Council, added: "The role of Barnbow in the history of Leeds is huge, and the women and men at the former munitions works showed huge determination, fortitude and sacrifice which kept the city and the country going during the First World War.

"By giving the site heritage protection the story behind the Barnbow lasses can continue, helping preserve their legacy and ensure future generations understand the impact they had on lives today."
