What's more gothic than dark satanic mills

You are getting downvoted because the largely American audience here doesn’t get the reference: https://oxfordsong.org/song/jerusalem

There doesn't seem much mention of gothic in that https://en.wikipedia.org/wiki/And_did_those_feet_in_ancient_...

One of the interpretations of the poem is that it criticises organised religion and that the mills in question are the church as an organisation represented in concrete terms by the church buildings.

I think they moved them to Canary Wharf and covered them in glass.
