Wat Arun Ratchawararam Ratchawaramahawihan (Thai: วัดอรุณราชวราราม ราชวรมหาวิหาร) or Wat Arun (Thai pronunciation: [wát ʔarun], "Temple of Dawn") is a Buddhist temple (wat) in Bangkok Yai district of Bangkok, Thailand, on the Thonburi west bank of the Chao Phraya River. 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 landmark. The first light of the morning reflects off the surface of the temple with pearly iridescence. Although the temple had existed since at least the seventeenth century, its distinctive prang (spires) were built in the early nineteenth century during the reign of King Rama II.
Wat Arun, locally known as Wat Chaeng, is situated on the west (Thonburi) bank of the Chao Phraya River. It is easily one of the most stunning temples in Bangkok, not only because of its riverside location but also because the design is very different from the other temples you can visit in Bangkok. Wat Arun (or temple of the dawn) is partly made up of colorfully decorated spires and stands majestically over the water. Wat Arun is almost directly opposite Wat Pho, so it is very easy to get to. From Saphan Taksin boat pier you can take a riverboat that stops at pier 8. From here a small shuttle boat takes you from one side of the river to the other for only 3 baht. The temple is open daily from 08:30 to 17:30.
