Prompt: in the centre of a large abandoned dirty field where a chemical spill was, is an extremely tall, 180 metre tall Victorian brick chimney. It is all that remains of the former chemicals factory that caught fire and exploded many years ago. Several more modern warehouses surround the site, though still grubby and unpleasant. This view is seen from the motorway. You can see the chimney from miles away. The site is bordered off by a large barbwire fence around the parameter of the site.
