Many of the buildings had been designed by 19th century architect, Francis Edwards, and had considerable merit.
In the film many of the buildings are easily recognisable - and must have been a sad sight for those who had maintained them in good order and worked there for many years. However it the film is worth seeing for the old gas works shots - despite being about about an American military subject.
I am attaching some of my not very good photographs taken soon after they were wrecked - taken from some distance and sadly not really showing the slogans - and I am now very sorry that I didn't get better and more interesting shots. It was a pretty dramatic site.
