temples like this are all over SE Asia, I first encountered one in Malaysia and that was my first exposure to the swastika being anything other than a third Reich symbol. I never knew it before then. Did you notice how the Buddhist swastika seems to go in both directions? Maybe it is just so it is visible properly from both sides of the fence.
i hadn't noticed that until you pointed it out but looking at a wiki about it, it appears as thought i actually does go both ways
