Heritage features along the GreenWay corridor and within the GreenWay catchment include:
- Aboriginal archaeology and sites along the Cooks River;
- The central sandstone arch and the balustrade from the original Battle Bridge which is listed as an item of State Significance on the New South Wales Heritage Register;
- The heritage-listed cast iron sewer pipeline at Hawthorne Canal crossing the pathway at Cadigal Reserve built in the 1890s;
- The two 1880s Whipple Truss bridge sections from the railway viaduct at Lewisham which when constructed was the longest in Australia (pictured right); and
- The heritage listed Waratah Mills and Mungo Scott Flour Mill, (the former converted to unit development in 2003.)
The rich history of the area was showcased with new interpretive and orientation signs installed as part of the GreenWay Sustainability Project in late 2012.
"Hawthorne Canal - The History of Long Cove Creek" written by Mark Sabolch and published by the Ashfield & District Historical Society in Association with the Inner West Environment Group in 2006 gives an excellent account of the history of the creek and its surrounds, which include important aspects of the GreenWay.
