I'm looking for recommendations for really unique or unusual Buddhist temples in Thailand. I already have a few on my list.
Wat Sala Kaew Koo - Nong Khai
Wat Chedi Hoi - Pathum Thani
Wat Phai Rong Wua (hell temple) - Suphanburi
Wat Lan Khuat - Sisaket
What other temples should be on the list and why?
