WAT KHOK CHANG (วัดโคกชาง)
Wat Khok Chang or the Monastery of the Mound of the Granary (1) was located
on the city island in the northwestern area of Ayutthaya in Pratu Chai sub-district. The
temple was located on the north bank of an ancient canal called
Khlong Chang Maha
Chai. Wat Sing was north of the temple, while Wat Jom Thong stood on its south.

There are no traces anymore of the former monastery. A Thai Army camp  (Old
Cantonment) had been constructed on the site. The temple has been classified as defunct.

Historical data about the monastery and its construction are unknown.

The site is mentioned on
Phraya Boran Rachathanin’s map drafted in 1926 and on a mid-
19th century map. On the latter map the monastery is denominated Wat Racha
(วัดราช). To its west was Wat Noi.

Wat Khok Chang is indicated on a 2007 Fine Arts Department GIS map south
of Khlong Chang Maha Chai in Geo Coord: 14° 21' 13.94" N, 100° 33' 2.11" E. The
two oldest maps positions Wat Khok Chang clearly north of the Chang Maha Chai
Canal, which let me presume that the brickwork found in the mentioned coordinates
should have belonged to another unidentified structure.

Wat Khok Chang should have been approximately located  in Geo Coord: 14° 21'
13.94" N, 100° 33' 2.11" E.

Footnotes:

(1) ฉาง = barn, granary or storehouse. The temple was likely named after the
Maha Chai granary in its vicinity.
