This month, the theme for the City Daily Photo community is "Mystery Object". I had a couple of excellent candidates for that, but unfortunately, I had used them before, here and here; so now I've had to rummage through a jumble of images to come up with this one.
All I can tell you is that it is on top of the Thirusoolam hill. What was it used for? I'm not sure, but I guess it was just a shaded rest / lookout point.... like the chattris on some forts in north-western India. I do hope some of the readers will be able to throw more light on this!
