Horace Mills, Cononley

In 1837, two separately owned textile mills were built close together and in parallel, by the River Aire.

In 1910, it partly rebuilt the mill, adding a fourth floor, and possibly reconstructing the north wall, with larger windows.

The southern part of the mill was given over to the production of motors, under the direction of Peter Green's son, Horace.

The site was steadily expanded over the following decades, and during World War II, it produced high frequency alternators for ADSIC.

Meanwhile, the larger part of the Aireside Mill was destroyed in a fire in 1992, the remaining single-storey section becoming a business park.
