    I watched a show that asked this question. The undisputed champ was Hoover damn Mt. Rushmore with an estimated expected life of hundreds of thousands of years.

    EDIT: It was Mt Rushmore not Hoover Dam.

      Hoover Dam is also expected to last a long time. The forces on the structure are mainly compression and it isn’t a seismically active area. The big question is whether the electricity generating turbines would fail open or shut.

        What about servicing those turbines so they don’t fail at all? “This dam powers our city since 4000 years.” Sounds nice and Star Trek-ish doesn’t it?

          You can service them so they last forever as long as there are people to service them.

          I’m talking about when a piece of infrastructure becomes a ruin.

        For sure, but Rushmore and the Pyramids have basically no time limit. The Pyramids might get buried by the sands though.

        No. It was one of those History Channel (maybe TLC or Discovery) thought experiment shows like “what would happen if all humans disappeared”. The dogs was a hard watch. I didn’t need to think about doggos starving to death at home as they waited for their humans to return. Strong Futurama’s Jurassic Bark feels.
