Wat Pho is considered one of the biggest amongst hundreds of Buddhist temples in Bangkok. There’s no clear evidence to tell us when the temple was firstly built. According to the earliest historical record, historians suggest that the temple has existed here for over 250 years before the founding of both the capitals of Thonburi and Bangkok. Eventually, when King Taksin made Thonburi the capital of Siam on the other side of the river in 1767. The King then ordered renovation to the temple and made this temple a Royal Monastery.
