    Funny enough. I just thought about it. I searched and couldn't point out any.

    Isn't that sad?  We modern folks tear down to make room to build anew. We continually erase traces of ourselves. I think that is very peculiar. Thank you for your reply palmagolden and Happy Saturday! :)

    The human race will never think in those terms anymore. I guess you can say that our mindset has dumbed-down through the centuries. This post was edited by Zack at November 4, 2017 1:37 AM MDT

    We build for short-term, not long-term. We don't treasure the past. We erase it. Go figger! Thank you for your reply Zack and Happy Saturday! :)

    Greece has the largest Rubbish tip in the world....they recycle noting ....the site is so vast and the ground level has risin 700 metres higher......when Rubbish lorries drive across the site the whole Rubbish pile moves.....

    They  never sweep up or keep the site clean and the whole place looks like a tip.......

    Quiet a few would if left to Nature, though change of use or disuse, and erosion, would considerably alter them. It is highly unlikely any would survive millennia intact.
     
    So what would leave at least significant traces?

    Large earthworks like road and railway embankments, cuttings and tunnels, to some extent.

    Massive concrete structures such as military blockhouses and bunkers, at least some dams and harbour walls to some degree.

    The more heavily-built roads though probably not recognisably, and after centuries of disuse their ruins would be buried below soil and vegetation.

    Quarries (if you can call big open holes in the ground, "structures" and "built").

    Some mines, though probably not coal-mines.

    Foundations of buildings, below the soil and vegetation.
