Wat Phisua (1) was located off the city island in the northern area of Ayutthaya in the Khlong Sra Bua sub-district, Moo 6. The monastery was situated west of the road running parallel with Khlong Hua Ro (2), south of Wat Khruttharam and west of Wat Khae, adjacent to the former location of Wat Lamut. Wat Phisua was in Thung Kaeo (3).
Wat Phisua is an unrestored and rather large ruin, totally covered with vegetation. Access is somehow a bit difficult. Remnants of the outer wall and some chedi foundations can be seen, while orange-red flat bricks are shattered all over the place. Observing the digging holes, the site has been a victim of treasure farming in earlier times. The monastery is surrounded by a moat (clearly visible from satellite pictures).
Historical data about the monastery and its construction are unknown.
The site features in a 1993 and 2007 CE Foreign Arts Department map.
Some temple remains are found in geographical coordinates: 14° 22' 29.46" N, 100° 33' 35.91" E.
