What are the foundation details? It might have a significant
possibility of toppling due to subsidence (especially given the
terrain that was there prior to the city).

Or ice. Someplace like a rain shadow desert with little sand
(Atacama?) might be ideal, at least for a couple of 10 ky or so.

Although "huge" is certainly not needed for preservation. With only
the micrometeroid flux, even the Apollo artifacts will remain in place
long after we're gone (assuming we, of course, don't mess them up
first by going back. Which is looking more & more likely).

Or using a Soletta to focus the solar image enough to melt large
chunks of regolith. As a very very *very* young feature, even after a
lot of late bombardment that would be clearly discernible to anybody
who can count craters, even 4 Ga from now.
