Wat Arun Ratchawararam, commonly known colloquially as Wat Chaeng or simply Wat Arun, is an ancient temple that was established during the Ayutthaya period. The temple earned the nickname "Wat Chaeng" because King Taksin returned from battle just as dawn broke. The temple's central stupa is often highlighted by international visitors for its stunning beauty, both inside and out. Located alongside the Chao Phraya River, it is easily accessible and offers a refreshing atmosphere. The riverside views provide a perfect backdrop for capturing beautiful photographs.
