Indeed, the axial lines of a nave guide people just as a well‑planned corridor guides a thief; if you align the transepts precisely you can predict where a suspect will turn, just as a good plan anticipates every step. But even the most symmetrical structure still allows a clever mind to find a loophole, like a misplaced window.

You’re right, a single window breaks the rhythm of the whole plan, and that is where a thief will focus his attention. In a perfectly executed design the window is either covered or reinforced, so the “unsymmetrical” element becomes a warning sign rather than an opportunity.

Exactly, a window that’s not just a passage but a sensor of sorts turns the thief’s advantage into a trap. It’s the same principle that keeps a building safe during a storm – you plan for the unexpected, and the structure responds before the threat does.
