It couldn’t possibly be an old monastery or anything else?

At a 12,000 foot altitude? On that utterly barren mountain?

I dunno. Sounds like an unlikely place to build a monastery, even if you wanted a remote location. The top of Mt. Ararat might as well be Mars.

I'd like to see some detailed drawings/photos of the layout of that structure to get a better sense of what it might have been.

Average settlement altitude in Tibet: 16,000 ft.

Facts are utterly stubborn things.
