Have you guys seen Paris underground cavern? There was another documentary about a Cathedral which I don't remember what it is called. But, in one
line they said "they had to put rocks underneath the cathedral to stop it from collapsing." It had an underground cavern with a very deep hole that
you can see water from the lake/river. It was said they got the stone from there to build the cathedral itself. There is probably a reason why many
newly discovered cities are underwater.
Where do you think we get the rocks from? Earth of course. We dig up the rocks and build the buildings, walls and towers. This of course makes the
land vulnerable to sinking. Especially, if you place your buildings where you dig the rocks from like that cathedral I was talking about.
This is one reason why some ancient buildings like China's great wall or Greek buildings isn't underwater. The Great Wall is built on top of the
mountains, and the Greek buildings were built on top of hills. The rocks came from else where. If you dig a hole deep enough underground and put heavy
stuff on top of it, it will collapse and sink.
There is probably a reason why many civilizations or walls are buried underground or collapsed into the ocean. It is like the some sewers, you dig too
deep, the ocean/lake water has access to the tunnel easily. Therefore, can flood the tunnel due to the same ground level. With heavy buildings on top,
it will have a chance to collapse the tunnel bringing the buildings down with it.
