Halifax has a rich industrial history, with many large-scale factories based here for many years.
They cover a range of industries, from confectionary, to metals and fabrics.
We've delved into our archives to find some fascinating pictures from the noughties which document the work going on inside the factories.
The pictures include staff and machinery from Nestlé, Dobsons sweet factory, Hargreaves Foundry, and John Holdsworth’s Shaw Lodge Mill.
Take a look through the gallery to see some fascinating pictures of Halifax factories and industry in days gone by.
