"Perhaps the most unique temple in the Kingdom of Thailand, the White Temple was born from the devotion of National Artist Chalermchai Kositpipat. A deeply devout Buddhist famed primarily for his religious-themed paintings, Chalermchai began the White Temple in 1997. Wat Rong Khun however is no traditional temple. Chalermchai re-imagines Thai art for the modern world. As you move through the temple grounds, you find yourself in the artist’s surreal vision of Buddhist teachings."
