Founded in the city by George Bassett in 1842, the confectionery company initially operated from Broad Street in the Park district, then moved to a large site in Owlerton in 1933.
Best known for producing Liquorice Allsorts, as well as Jelly Babies and Trebor Mints, today the Beulah Road factory is run by the giant multinational Mondelēz following several mergers and acquisitions.
Here are 10 pictures looking back at the firm's history.
