I don’t know what this building used to do at Royal Ordnance Factory (ROF) Wrexham, but I suspect it was something dangerous that involved making or processing something lethal. Either way, it’s remained unused for over 60 years, the only evidence left being the foundations for something, and a large sunken pool of water at one end of the building. With the majority of the old ROF buildings long since demolished, I wonder how much longer this will last, hidden amongst the thick brambles and nettles.
