Very interesting.....thanks for posting. My father worked at Ardeer during the war. Most of the dispersed munitions bunkers are still there and can be seen on Google Earth... plug in : 55°38'02.6"N 4°43'35.7"W
Never heard of this place, although I've been to a similar place long ago. Quite a bit online and this is from a 2019 article: From: https://harcruins.wixsite.com/ruina...s-abandoned-places-as-islands-of-biodiversity and Ardeer, Ici Works, Nobel's Explosives Factory | Canmore The factory was an ICI plant or ICI Noble was an explosives factory for the best part of a century before closing in the 1960s. Lots of recent reports on the site, with photos. See: Report - - Ardeer ICI bomb shelters and surrounding areas. | Industrial Sites Note a train enthusiast site states the site was open till 1996, although other sites refer to an ICI Noble factory remaining on a nearby smaller site. See: Industrial Narrow Gauge Railways This might explain better when the plant closed! The punchline is the last sentence: From: Secret Scotland - ICI Ardeer There was a local museum once. See: The Big Idea (museum) - Wikipedia Google mapping suggests the plant extended across the River Garnock; plus a photo on previous link. If you search Google maps with ICI Ardeer map there is an annotated map which is really useful. Yes, the site extended across the river.
