Three Mills Wall River, Bow London – The Three Mills Wall River is part of a system of canals and waterways that once powered the mills located at Three Mills and just beyond on what is today the London Olympic Park. An old industrial slice of London where grain, gin and acetone were once produced is slowly being eroded by the march of apartment blocks and the alure of canal side living. I am sure a few vestiges of the industrial past will remain, perhaps a lone chimmney – to remind the new residents of what came before here.
