Wat Chumphon, or the Monastery of the Concentration of Troops, was located off the city island in the eastern area of Ayutthaya, in Khlong Suan Phlu Sub-district.
Wat Phra Non and Wat Kradok were situated east. The three monasteries could be accessed by the canals Khlong Suan Phlu, Khlong Dusit and Khlong Phra Non.
The foundations of the monastic structures were restored, except for the chedi in the west.
Historical data about the monastery and its construction are unknown.
At least three other monasteries off Ayutthaya's city island are called "Chumphon". One site is situated in the northwest in Wat Tum Sub-district (Wat Chumphon 1), a second one in the north in Suan Phrik Sub-district (Wat Chumphon 2) and a third one in the south in Pak Kran Sub-district (Wat Chumphon 4). These monasteries were probably related to warfare and were gathering points for the local male population before going into battle.
A 1974 CE Fine Arts Department map suggests that Wat Chumphon was south of what some historians believe was a Baray (Khmer water reservoir) related to the location of Wat Yai Chai Mongkhon, which was likely a Khmer sanctuary before. (1)
Some temple remnants were excavated by the Fine Arts Department (FAD) in geographical coordinates: 14° 20' 27.20" N, 100° 35' 15.79" E.
