Recently, I decided to visit some well-known Thai temples here in Bangkok. It had several years since my first visit and wanted to see what had changed. The first temple I visited is called Wat Arun or the Temple of Dawn.
Wat Arun, commonly known as Wat Jaeng or the Temple of Dawn was formerly Wat Makok in the Ayutthaya period. When King Tak Sin made Thomburi his capital and decided to build his palace on the West bank of Chao Phraya River, Wat Makok was made the palace temple and renamed Wat Jaeng. King Rama lV later changed the name to Wat Arun Ratchavararam as it is called today.
BTW, I did not know these facts offhand, I just copied from the brochure.
First came the warnings. It seems some tourist guides are not always what they seem to be.
