Wat Khok Chang, or the Monastery of the Mound of the Granary (1), was located on Ayutthaya’s city island in the northwestern part of the Pratu Chai Sub-district. The temple was located on the north bank of an ancient canal called Khlong Chang Maha Chai (2). Wat Sing was north of the temple, while Wat Jom Thong stood south.

There are no traces anymore of the former monastery. A Thai Army camp (Old Cantonment) had been constructed on the site. I classified the temple as defunct. Historical data about the monastery and its construction are unknown.

Wat Khok Chang on the maps

In my opinion, Wat Khok Chang figures under the name of Wat Rat (วัดราช) on a 19th-century map by an unknown surveyor. Wat Rat stands north of Khlong Chang Maha Chai, opposite Wat Ket (Wat Jom Thong on Phraya Boran Rachathanin’s map). Wat Noi and Wat Sop Suan stood west and Wat Lok Sutha east.

Wat Khok Chang shows on Phraya Boran Rachathanin’s map drafted in 1926, as mentioned above, north bank of Khlong Chang Maha Chai. Wat Jom Thong stood on the opposite side of the canal in the south, Wat Sop Sawan west and Wat Lok Sutha northeast. Phraya Boran (1871-1936 CE) was the Superintendent Commissioner of Monthon Ayutthaya from 1925 till 1929 CE but occupied important functions since 1896 CE in Monthon Ayutthaya.

Wat Khok Chang is indicated on a 2007 Fine Arts Department (FAD) GIS map south of Khlong Chang Maha Chai in geographical coordinates: 14° 21' 13.94" N, 100° 33' 2.11" E.

The two oldest maps positions Wat Khok Chang north of the Chang Maha Chai Canal, which lets me presume that the brickwork found in the mentioned coordinates by the FAD should belong to another unidentified structure.

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


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

(2) Khlong Chang Maha Chai, or the Great Victory Granary Canal, is a defunct waterway on Ayutthaya's city island in Pratu Chai Sub-district. The east-west running canal had its mouth at the old Lopburi River in front of Wat Thamma and linked up with Khlong Pak Tho. The canal passed the fortified city wall at the Chang Maha Chai Gate, a large water gate between Wat Suan Luang and Wat Sop Sawan. The canal has been filled up somewhere after the fall of Ayutthaya (1767 CE), and no traces of the waterway are left today.
