Probably Japanese architecture. They make some insane stuff.
Its either that or the great wall of china
Actually proven? Pyramids probably.
The pyramids at Giza immediately leap to mind. They've withstood thousands of years of the elements, primarily because they were built by people who were clever enough to figure out that certain places don't make for great longevity. If you build something where there are volcanoes, earthquakes, tsunamis, hurricanes, tornadoes, landslides, flash floods, avalanches, wild fires or Mormons, your structure will eventually be destroyed. The moral of the story? Everything should be built at Giza.
Clearly you've never been to Utah.lol, whut? all they do is knock on your door during supper and engage in group sex. they don't destroy stuff
is that forreal? lol. srsly what IS that arch made out of.
