Find the origin of that painting with the towers, since that is your evidence, let's start there. 

There is no point discussing it, if it was never meant to show the event you speak of, no matter how many websites post it as such.  Also no point if the painting was done in the 14th or 15th century, or any time not contemporary with the event, since they would just have been dreaming up the scene and there would be nothing to look for.

It's not a painting. It's an illustration from a medieval manuscript which is all I can recall about it.

Both the VMS drawing and this illustration were likely made after the event, which could account for one or the other making a mistake regarding the top of the cone, as pointed out by JP. From a distance, a very narrow saddleback might look like a cone. A cone with two flags from a small opening on the top would be another possibility.

There can be no doubt that the illustration depicts Montségur: the winding path, the catapult, the French soldiers on the left, and the bonfire in a field below, all point to Montségur.
