The main temple has Burmese-styled roofs (multi-layered and cone-shaped) which is rare in Thailand. Interesting and beautiful enough. Other buildings are quite ordinary.
I'd give four stars for the main temple, but unfortunately there were many dogs in the temple ground, and I was chased by a pack of puppies which seemed to consider a small chedi I tried to reach as their territory. I know this might sound humorous, but Thailand still hasn't got rid of rabies and you should avoid dogs there. Why don't they train them? Minus one for that.
By the way, if you go to this temple, pay a visit to Baan Sao Nak, a beautiful teak-wood house built in 1985. It's along the way to the temple from the town.
