King Prasat Thong (r.1629-1656) built this royal monastery on the bank of the Chao
Phraya River in 1630 in order to make merit for his foster-mother, as well to show
himself as a man of great Buddhist merit; in fact a political goal [4]. The temple was built
on the site where his foster-mother, the wife of Okya Sri Thammathirat, resided in
Ayutthaya.
