Greenfield Valley Heritage Park, Holywell, Flintshire, Wales,
The Lower Cotton Mill lies in the Greenfield Valley, Holywell, North Wales. The large rectangular ruins are all that remains of the six storey cotton mill built here in just 10 weeks in 1785. The Cotton Twist Company employed up to 300 apprentices, many of them under 10 years old. The cotton mill closed in 1840 but it reopened as a corn mill in 1850, producing flour until the early 1900's.
