Wat Pom Noi, or the Monastery of the Little Fortress, was located off the city island in the western area of Ayutthaya in the Ban Pom Sub-district.
The monastery was located along the connection canal leading to the Chao Phraya River (1) at Hua Taphan via Khlong Maha Phram (2).
The site can be accessed via Road No 3412.
Wat Pom Yai was north.
Wat Phukhao Thong was on the opposite side of the Chao Phraya River in the northeastern direction. Wat Tha (Ka Rong) stood southeast.
Between Wat Pom Yai and Wat Pom Noi was a canal called Khlong Wat Pom (some maps have Khlong Worachet as the waterway led to Wat Worachet). Opposite the origin or mouth of this klong was another canal leading to Wat Phukhao Thong called Khlong Yai.
The name of the monastery is related to the prominent wooden forts which were in the four directions in the late Ayutthaya era. The position of one of these forts can be seen on a map by Jacques Nicolas Bellin (1703-1772 CE): Carte du Cours Du Menam Depuis Siam Jusqu'a La Mer Levee sur les Lieux par un Ingenieur Francois and published as plate no. 5 in volume 9 of the 1752 French edition of Abbe Provost's L'Histoire Generale des Voyages.
There are houses situated on the site, which are private property. Although I could not access the site, nothing likely remains of this monastery above ground level.
The monastery's historical background and period of construction are unknown.
The site was in geographical coordinates: 14° 21' 42.8" N, 100° 32' 07.4" E.
