I loved this temple.  There's nothing ornate about it, and I'm not sure how historic it is.  But as a place to worship, it was lovely.  The space is rather cave like, with the god in his room, and a small priestly anteroom to the left of him.  The priests are very attentive and active, and there was singing.  I love temples with live music, and in this one, several of the worshippers sat down and joined in. 

After we stayed for a bit, Amma found out that the temple serves food to worshippers at lunch, and it was almost lunch.   So we stayed for a wonderful lunch overlooking the river

Unfortunately, I hardly took any pictures of this temple.  But I found a wonderful video here that goes inside the sanctum.
