WAT THAM NIYOM (วัดธรรมนิยม)
Wat Tham Niyom or the Monastery of the Revered Dhamma is a temple in use by
the monastic clergy and located off the city island in the eastern area of Ayutthaya in Hua
Ro Sub-district.
Wat Nang Chi (defunct) stood in the north, while Wat Jan (defunct -
formerly opposite of the railway station) stood on its southern side.

Wat Tham Niyom features on a
mid-19th century map as Wat Yom Thai. The map
indicates no chedi nor prang in its location. Wat Yom Thai and
Wat Yom Mon were
situated about 200 meters from each other following a Fine Arts Department excavation
map drafted in 2007. Wat Yom Thai stood south of Wat Yom Mon, identical as
indicated on the mid-19th century map. On
Phraya Boran Rachathanin's map drafted in
1926, the monastery is named
Wat Yom.

Wat Yom had before mural paintings illustrating scenes of a royal barge procession
almost fitting the scribes made during King Narai's reign on royal processions both on
water and on land (1). Phraya Boran Rachathanin had the murals at Wat Yom copied on
a manuscript in 1897. Prince Damrong Rachanuphap had the mural paintings recopied
on manuscript in the begin of the 20th century and preserved at the National Archives in
Bangkok. The original murals are unfortunately destroyed.

In 1985, the Muang Boran Publishing House released entire books about the murals at
Wat Pradu Songtham and Wat Yom. The murals at both monasteries are viewed as
