Plenty of things build today will last much longer:

Every nuclear waste disposal site (hopefully)

Seed vaults

Nuclear bunkers

Plastic packaging will quickly tear into microplastics, which indeed will last centuries

Concrete doesn't last, stone does. Brick to a lesser extent.

*Concrete with rebar. Roman concrete has lasted plenty long. Though the lime in it helps.

That is true. Roman Concrete is still standing 2k years on. Ours lasts decades, maybe a century if well done.

They used ash from Mount Aetna in Sicily to make some of it. I forget the thing with the lime, how that was different than what we use?
