Wat Arun, Wat Chaeng, Temple of Dawn is a Buddhist temple in Bangkok Yai district of Bangkok.
The temple derives its name from the Hindu god Aruna often personified as the radiations of the rising sun. Wat Arun is among the best known of Thailand's landmarks and the first light of the morning reflects off the surface of the temple with pearly iridescence. Wat Arun was envisioned by King Taksin in 1768. It is believed that after fighting his way out of Ayutthaya, which was taken over by a Burmese army at the time, he arrived at this temple just as dawn was breaking.
