Wat Arunrajawararam Rajaworamahavihara ( Wat Chaeng ) is situated on the west, or Thonburi bank of the Chao Phraya River opposite Wat Phra Chetuphon Wimonmangkhalaram (Wat Pho). Originally it was named Wat Makok, and later, Wat Makok Nok, as it was paired with Wat Makok Nai (Wat Nuan Noradis). It is said that after fighting his way out Ayutthaya, which was besigned by a Burmese army, King Taksin arrived at this temple just as down was breaking. He later had the temple renovated and renamed it Wat Chaeng, the Temple of the Dawn. During his reign, which is called the Thonburi Period, WatChaeng was the chief temple, and for time.
