Giant UFO: Beneath a Massive Structure? Macchu Picchu – Peru?

Like user TomHanksYo said it needs to be:

Outside the US A large, well known, laudatory landmark “They” built a building over it (could mean US/allies or could mean a building was already built over it, but his framing suggests US or ally built it)

My theory is that since Macchu Picchu is in a really high altitude, it may have room for something underneath it? Also it was discovered (by the old world) not so long ago tbh (1902 by Hiram Bingham). Also in Peru there is Marchuasi (a usual UFO sighting site), Nazca lines depicting humanoids, Nazca mummies, facepealers, jet-pack “miners” etc.

Now recently Peru let the US army in to do some “training” but yet nobody knows where they at or what are they doing

What do you guys think? Is Peru a hint/clue?
