As you’re walking the long path through the water gardens, you’ll note that the right side is excavated, so you can see the pattern of the gardens, the stonework and brickwork created by the pools — the left side is mostly a big pond, not yet excavated by archeologists.
I don’t know if that’s a deliberate choice, so you can see the process of archeology and the effect of time and history on what King Kasyapa tried to build? It all disappeared into the jungle for centuries, and while locals would have known it was there, and stories would be passed down, it took some serious work to unearth it all again. It’d be cool, if they did this deliberately, and planned to leave it that way — but maybe they just haven’t gotten to the left side yet? I don’t know!
Another view of the unexcavated side.
