These are very hard rocks, so there are no cavities within the rock. I think it was proven that the water on the Sigiriya castle was stormwater, waterborne from the rain. not the groundwater. So there are no pipes, no elevators, and no cavities within the Sigiriya rock. The Sigiriya rock is older than two billion years. Imagine that this rock still stands while some of its contemporary mountains are eroded away. There was a huge mountain range in the New York City area. which assumed something like the Alps. Now that it had been completely eroded away, the remaining mountains existed as the Appalachian Range.  <a href="https://gizmodo.com/how-an-ancient-mountain-range-made-nycs-skyscrapers-pos-1596992514" target="_blank">https://gizmodo.com/how-an-ancient-mountain-range-made-nycs-skyscrapers-pos-1596992514</a></p></blockquote><p></p>
