View of Marshall's Mills on Marshall Street. On the right is part of the original building while on the left is the Temple Works extension. The original six-storey mill dates back to 1791-92 when John Marshall established his flax-spinning business here, drawing water from the Hol Beck to power revolutionary machinery developed by Matthew Murray, who was employed as an engineer in Marshall's mill at Adel. In the 1840s the Egyptian-style Temple Works were added, believed to house the largest single room in the world at the time. Together the two mills employed over 2,000 workers, using 7,000 steam-powered spindles. The original mill, now a Grade II* listed building, was comprehensively redeveloped in the 1990s and is now used for offices. Temple Works, Grade I listed, is presently being used as an arts centre.
