The site is not indicated on a mid-19th century map, but features on Phraya Boran Rachathanin's map drafted in 1926. Some remains of the temple were excavated by the Fine Arts Department (FAD) in Geo Coord: +14° 20' 15.49" N, +100° 33' 12.74" E.
Footnotes:
(1) It is more than likely Wat Daeng in the southern area and not Wat Chedi Daeng in the north as first, Wat Krachai, Wat Tao and Wat Thong were located in the southern area; second, the chronicles state that the Burmese General Posuphla just established his stockade at Pho Sam Ton; and third it is still the year 1766 and still a few months before the fall of Ayutthaya.
