WAT SING PAK NAM (วัดสิงปากน้ำ)
Wat Sing Pak Nam or the "Monastery of the Dwell at the Mouth of the River" was
located off Ayutthaya's city island in the southeastern area at Ko Rian sub-district. The
temple stood on the east bank of the Chao Phraya River and at the mouth of the
Suan
Phlu canal just opposite the English settlement in an area called Pak Nam Mae Bia
(ปากนำแม่เบี้ย).

The mouth of the canal was in the Ayutthayan era, a thriving market (Pak Khlong Suan
Phlu floating market) and a gathering point of merchants from the South. [1]

There are no traces remaining in situ.

Its historical background and period of construction are unknown.

Wat Sing Pak Nam is mentioned on
Phraya Boran Rachathanin's map drafted in 1926.
