An area of woodland within the Porter Valley parks. It forms part of the sequence of linked parks leading from near the city centre out to the edge of the Peak District. Whiteley Woods was gradually acquired by the city council between 1897 and 1932. The Porter Brook was a fast flowing stream which was utilised by numerous water powered industrial sites. Significant remains of these works including weirs, mill dams (ponds) and goits. The polygon contains the remains of the Whiteley Wood Rolling Mill or Wire Mill, operated by Thomas Boulsover of Old Sheffield Plate fame, and the Leather or Holme Wheel. Both wheels were constructed in the mid 19th century. Legibility of the industrial past is significant.
