I read today that the minaret / chimney thing is intended as nod to Lancashire's mill heritage
Sort of. If they wanted to really celebrate local heritage they should've used New Red Sandstone or Accrington Brick for the design instead of whatever it is they're using.
I feel like the designer just went with whatever and then, realising they missed a crucial part of the brief, used their pencil rubber to rub the minaret top out, and called it a mill chimney inspiration. 🤣
