Wat Mae Nang Muk is a temple ruin located on Ayutthaya’s city island in the Pratu Chai Sub-district. The sole remaining stupa stands on the premises of the Ayutthaya College Alumni Association on the corner of Rojana Road and Chikun Road.

The monastery stood between Khlong Pratu Thep Mi and Khlong Pratu Jin, south of Wat Chatthan (defunct), west of Wat Khun Mueang Jai (ruin) opposite the Pratu Jin Canal (defunct) and east of Wat Pa Sak (ruin).

The stupa is a twenty-rabbeted-angled chedi in a square plan, popular in the fourth sub-period of the Ayutthaya era (1732-1767 CE). There are false porticos in each cardinal direction, probably containing standing Buddha images at earlier times.

The establishment and history of Wat Mae Nang Muk are unknown.


Wat Mae Nang Muk is indicated on a mid-19th century map drafted by an unknown surveyor but named Wat Noi Nang Muk (วัดนอยนางมุก). The monastery was situated just north of Wat Kaeo and west of Wat Sao Chingcha and Wat Khok Suea. The monastery stood on the west bank of Khlong Pratu Jin and south of Pa Thon Road and Wat Chatthan. The 19th-century map indicates the presence of a chedi.

There are discrepancies between the mid-19th century map and Phraya Boran Rachathanin's map drafted in 1926 CE regarding the area west of Khlong Pratu Jin. On the oldest map, Wat Chatthan is situated north of Pa Thon Road instead of south. Phraya Boran Rachathanin positions in this location the Place of the Deities or ‘Thewa Sathan.’ Phraya Boran (1871-1936 CE) was the Superintendent Commissioner of Monthon Ayutthaya from 1925 till 1929 CE.

Wat Noi Nang Muk is situated at the southwest corner created by Khlong Pratu Jin and Pa Thon Road (Chikun Bridge) and is positioned on the mid-19th century map in the location where today is believed Wat Chatthan stood.

The position of today's Wat Mae Nang Muk is on the mid-19th century map, in fact, Wat Kaeo. On the other hand, Wat Kaeo is drafted without a chedi or prang. In conclusion, the ruin called Wat Mae Nang Muk today could have been Wat Kaeo.

The ruin of Wat Mae Nang Muk is in geographical coordinates: 14° 21' 4.79" N, 100° 34' 7.31" E.
