On the pages of alexandrafl's livejournal, a photo of the Roman Forum was posted in the comments from this perspective:
Note the ground level on the left side of the arch. It would be absurd for the ancient builders to place it close to a wall or hill. I propose to see photos of the ruins of Rome in this place and draw some conclusions.
The cathedral on the right in this photo is above the level of the arch itself. We can, of course, assume that the builders adapted the architectural plan to the area, but in my opinion, this cathedral is just a younger building. And the point is not in the accumulated cultural layer, the thickness of which simply does not exist.
The entire area of ancient ruins is several meters lower than the surrounding (and whole) buildings. One gets the impression that this was all excavated.
But the soil has not been removed yet. Look at how thick it is - five meters, no less …
In the Middle Ages (or even in our time), they tried to build something out of bricks (or mask).
More recently, in our time, a road passed here. But later, apparently, they decided to continue excavations …
Ancient masonry of the base of some structure.
And here you can see how the base is covered under the columns.
An ancient stone base, and on top - a brick remake.
Reconstruction of the appearance of this territory. No hills or hills are expected.
Old photo (the road has not yet been poured)
The conclusion suggests itself this: as in the engravings and paintings of artists, you can see in more detail here we are observing the consequences of some kind of catastrophe that brought the buildings of Rome with a multi-meter layer of soil.
Addition. Excavations of Rome.
And, after all, skeptics and official historians are convinced that it was either a flood or just cultural layers. But the photographs show the excavation of the consequences of a large-scale planetary catastrophe that destroyed not only Rome …
