Wat Noina, or the Monastery of the Custard Apple, is a not restored ruin located off the city island in the southern area of Ayutthaya in the Samphao Lom Sub-district (1).
Wat Noina was situated west of Khu Cham (2) and south of the Chao Phraya River, just southeast of Wat Phutthaisawan. Wat Tamnak and Wat Tawet were located south of it.
The site lies within a village community, which uses the site for farming purposes.
In situ is a brick mound with fragmented Buddha statues. Part of the wall foundations still can be seen.
Its historical background and period of construction are unknown.
The remnants of Wat Noina are in geographical coordinates: 14° 20' 19.07" N, 100° 33' 43.20" E.
