WAT RONG THAM (วัดโรงธรรม)
Text & maps by Tricky Vandenberg - May 2010
Wat Rong Tham was a monastery situated off the city island in the eastern area of
Ayutthaya in present Phai Ling Sub-district.

The monastery stood (likely) south of
Wat Pradu on the south bank of the today defunct
Khlong Wat Pradu. The premises of Wat Rong Tham and Wat Pradu were merged to
become Wat Pradu Rong Tham, presently known as Wat Pradu Songtham. (1)

Its historical background and period of construction are unknown.

The site is indicated on
Phraya Boran Rachathanin's [PBR] map drafted in 1926. PBR
indicates Khlong Pradu south of Wat Rong Tham, but this might be incorrect and
possibly be another canal. Kaempfer positions Khlong Pradu north of
Wat Nang Chi
and above the mouth of
Khlong Pratu Ho Ratanachai on the opposite side on his map
drafted in 1690, hence Wat Rong Tham and Wat Pradu were separated by the canal.

Wat Rong Tham must have been located approximately in Geo Coord: 14° 21' 48.61"
N, 100° 35' 14.79" E.


(1) The renaming of "Rong" by "Song" seems to come from the following: "rong" which
means building, sounds also as coffin (Th: long). The word "rong" was not felt as a very
auspicious name for a temple, hence the name change. The same occurred to Wat Wong
Khong, before known as Wat Rong Khong and later changed into
Wat Wong Khong.
Other Ayutthayan temples which were merged at a certain stage are Wat Sri Pho (
Sri Pho & Wat Phrom Kalayaram) and Wat Tha Ka Rong (Wat Tha & Wat Ka Rong).
