A televised dig led by Manchester academics has unearthed details of the historic city's first cotton mill.
The team spent three days excavating the Miller Street site
Excavations reveal the outline of the mill and its water wheel pit.
The dig, being shown on Channel 4's Time Team on Sunday, is led by the University of Manchester's Archaeological Unit.
Presenter Tony Robinson and the team spent three days on the site for Rubble at the Mill: The Birth of the Industrial Revolution in Manchester.
The findings at the Miller Street site, which is under a car park in Manchester - one of the world's earliest industrial cities - are believed to date from the early 1780s.
The cotton mill burnt down after it was hit by a bomb in World War II and has been the site of a car park ever since.
Time Team were assisted by eight specialist staff from The University of Manchester Archaeology Unit, including Director Mike Nevell.
Mr Nevell said: "This site is of national and even international importance.
"The mill was built by Richard Arkwright who is often considered the father of the modern industrial factory system.
He added: "Within 18 years, Manchester became the biggest mill town in the world boasting around 50 mills.
"That set the pattern for every other industrial city."
