WAT NGU (วัดงู)
Wat Ngu or the Monastery of the Snake was situated off Ayutthaya's city island in the
northern area on Ko Loi (1) in Hua Ro Sub-district.

The temple is shown an a Fine Arts Department map drafted in 1974 (FAD 74) and was
positioned southeast of
Wat Monthop and southwest of Wat Khae. This temple was not
more shown on a Fine Arts Department map drafted in 1993.

In order to find out more information on this monastic structure, author made a visit to the
spot in May 2011. The following information was gathered: A villager recalled that Wat  
Ngu existed prior to Wat Monthop and the latter monastery in fact replaced the first. A
small monastic structure on the premises of Wat Monthop is said to have belonged once
to Wat Ngu (This information is probably wrong as Wat Monthop was already
mentioned in the Royal Chronicles of Ayutthaya). Other villagers knew about the
existence of Wat Ngu, indicating it was "rang" (emptied) but could not anymore indicate
its exact former location.

Looking on the FAD 74 map, we find Wat Monthop and Wat Khae more or less
correctly positioned.
Wat Khao San Dam, which is a still existent brick mound, is not
correctly positioned but slightly too much north.

If we shove the FAD 1974 map overlay in the sense that the position of the brick mound
of Wat Khao San Dam on the satellite picture is corresponding with the Wat Khao San
Dam on the map, than Wat Ngu should have been located in Geo Coord 14°22'0.67"N
100°34'39.84"E. At the same time the location of
Wat Sri Jampa should be situated
slightly northeast of Wat Khao San Dam (the position of Wat Sri Jampa, after interview
of villagers in its vicinity, proved to be correct). In the above mentioned geographical
coordinates traces of bricks and tiles were visible.

There are no traces anymore visible of the monastery above ground level.

Historical data about the monastery and its construction are not known.

The site is not indicated on a
mid-19th century map, neither on Phraya Boran
Rachathanin's map drafted in 1926. Professor Khemnad writes in his book “Monthop”
that Wat Ngu is mentioned on old maps situated in the middle of the island. [2]

Wat Ngu was one of the seven monasteries on Ko Loi. The other temples were: Wat
Monthop, Wat Khae, Wat Sri Jampa, Wat Khao San Dam, Wat Inthawat and
Wat
Saphan Kluea.

Wat Ngu was located in Geo Coord: 14° 22' 3.31" N. 100° 34' 36.85" E.

Footnotes:

(1) Ko Loi or "Floating Island" is surrounded in the north by Khlong Chong Lom, in the
east by the
Pa Sak River and in the west by the (new) Lopburi River. Khlong Chong
Lom has been dug in the early 20th century to reduce the whirlpools near Wat Tong Pu
and the
Chantra Kasem Palace, separating Wat Chong Lom from the eastern mainland.
As the Lopburi River and the Pa Sak River were joining near Wat Tong Pu and the
erosive force of the two rivers were destroying the embankment in front of the Chantra
Kasem Palace, the idea rose to deviate the Pa Sak River. This was done shortly after the
digging of Khlong Chong Lom.
Khlong Sai, a  small canal cutting through the eastern
main land, from Wat Chong Lom to the present Ayutthaya Ship Building Industrial and
Technology College, was widened and deepened. The Pa Sak River instead of running in
front of Wat Tong Pu, changed its course and ran straight from
Wat Pa Kho to Wat
Phanan Choeng. [1]
