After wandering around for 40 minutes, I stumble upon this really cosy corner, behind a minor temple at the edge of the complex. It is so serene and peaceful, that I actually sit on a rock there for a good 15 minutes, savouring the ambience and the bird-songs. There's a high stone wall behind the bulding, and the forest beyond it.
I notice stacks of pebbles under the tree. Must be the work of visitors (hopefully!), but I have no clue of its significance.
