I’ve explored Baylang Sanctuary a fair bit to look for wildlife; mostly birds. I had photographed these buildings but had never looked up the history of them. According to the Victoria Heritage Database,
The industrial complex contains buildings which relate to the former Phoenix Wool Scouring Works and as such has historical significance for its associations with the development of the woolen industry in Geelong. The timber building adjacent to Riversdale Road contains evidence of plant use for scouring and carbonizing activity. There is information, which suggest that the Phoenix works was the first business in Victoria to make a separate industry of this kind of work. Historical associations with Brig. General Robert Smith, its founder, are also important in the region.
These photos show the buildings from a closer perspective.
