There is so much structure to the Sigiriya gardens, and without the water, you can really see all the shapes they built. Structure is so important to gardens, but when I look at this I do notice the labor involved. So much work!
As a gardener myself, I know just how much of a pain it is moving even a few bricks or stones! Kings can command a lot of labor, though.
(That twisting path in the third photo would have been a little trickling stream. Just picture everything except that big main path filled in with water, and you’ll get a better sense of what it might have looked like in the 5th century.)
