Wat Phutthai Sawan or the Monastery of Lord Buddha of the Heavens is located
on the south bank of the Chao Phraya River in an area presently called Samphao Lom
(the Capsized Junk sub-district), east of Khlong Thakian. It is situated opposite the
mouth of Khlong Chakrai Yai, also called Khlong Tho, a canal linking the former
Lopburi River (present Khlong Mueang or northern moat) with the Chao Phraya River
and runs adjacent the former Royal Palace grounds. The temple complex faces east and
is bordered on the north by the Chao Phraya River.
