My neighbour has a tall chimney (for a wood burning stove) with a

from that direction (in fact the cable is to the SE of the chimney, and

poles. Any explanation? Is the pole put in at a bit of an angle so
it's always leaning one way?

Are you sure it's a cable and not a rigid rod/pipe that braces the flue?

I can't see from this far away. Are you suggesting it can take a force
in more than one direction? Even if it can, it would only be push and
pull, not sideways.

Maybe there is a second solid brace you can't see. That would
make a triangle.
Those are pretty solid.

If there's anything else it's under the roof tiles.
