Wat Tha Chai Siri

Wat Tha Chai Siri, also called Wat Tai, lies on Phetkasem Road with the Phetchaburi River on its north side. Its founding year is not recorded; the temple register says it received a royal grant for an ordination hall boundary (wisungkhamsima) in 1367, in the Sukhothai period, and again in 1682 under King Narai, the same year the ordination hall was built.

The principal image in the ordination hall, Phra Phuttha Siri Rot Chai Mongkhon (also called Phra Ruang Wat Tha Chai), is a standing Buddha in the gesture of warding off illness, in Lopburi style, over 700 years old and 2.75 metres tall.

The temple's landing is where water from the Phetchaburi River is drawn for royal coronation ceremonies, and it supplied bathing and drinking water for the royal court in the reigns of Kings Rama IV to Rama VI.
