Why are ancient buildings, cities and structures usually found buried underground?
In: 62
In addition to the other stuff mentioned in this thread, many cities and towns were just abandoned. For centuries. Sometimes due to plague decimating the population, or war, or the reason for the city’s existence ceasing to be there any more (a bend in a river moves, a sand dune moves and covers the city, a local mine getting depleted, etc.). So people pick up and move and never return.
So the buildings sit there, exposed to the wind, rain, floods, dust, and other weather with no people to sweep off the streets and sidewalks. And that just accumulates over the years.
If one seasonal flood can leave an inch or two of new dirt/mud on an abandoned city, it only takes 10 years for you get a foot of dirt. 60-ish to cover a typical 6 foot high wall. And if you come across a city covered in dirt and mud, you’re less likely to take up residence there. You’re going to search for a city with the modern conveniences you’re looking for. And over the course of a hundred years, or a few hundred, the city slowly gets buried and people tend to forget both that it ever existed, and where.
