Here I am again... for a curiosity.
In Britain, what exactly is the "heritage movement" ? Is it a "real" movement (structured, organized) that works for the preservation of the industrial patrimony? Or what else?
As far as I know, "movement" is used loosely here as an umbrella term for all sorts of organisations, such as the National Trust. Such organisations campaign for the preservation of our "national heritage", a term which is open to interpretation itself, but can include:
Historic houses/castles/manor houses
Other historic buildings - factories, potteries, churches, workhouses
Historic roads, bridges, railways
Preservation of the open countryside
Do you get the picture?
Of course, I might be completely wrong here, and discover that there is something called "The Heritage Movement"! I don't think so, though.
