It became a Grade II* listed building in 1980 as a distinctive work of British industrial architecture.
The main 5-storey spinning building is faced with local limestone and styled to resemble a country house, with square towers at each corner topped by stone urns.
Unusually, a large chimney for the furnace to power the mill's steam machinery issues from a dome at the top of a circular tower built into one façade.
Inside, the building is supported by cast iron columns that carry beams bearing brick vaults.
The millworkers went on strike for eight months from December 1913 to June 1914, over the right of workers to join a trades union, but the mill prospered in the First World War after receiving a large order for khaki cloth for the British Army.
