Present form appears to post date the 1967 OS. The polygon represents the location of the Needle works and Royds Works buildings depicted on the 1851 OS and recorded on the OS as PRN 1699 and 1700. These buildings were built along the mill race for Attercliffe Corn Mill / Royds Mill, and may have been water or steam powered - nb- The 1851 OS shows both boilers and cisterns at these works indicating the presence of steam engines. Possible partial survivals of features from earlier character types. 1851 mapping indicates 'local fields' of strip form.
