Wat Sra Si Liam, or the Monastery of the Square Pond, was located off the city island in the southern area of Ayutthaya in the Samphao Lom Sub-district (1).
The monastery stood west of the Khu Cham (2), south of the Chao Phraya River below Wat Phutthaisawan and Wat Tha Rap and west of Wat Noina.
The site is only mentioned on a Fine Arts Department (FAD) map drafted in 1974 CE.
A visit to the area with a request to locals to indicate the site resulted in finding brickwork and pottery shards in geographical coordinates: 14°20' 9.42" N, 100° 33' 39.04" E.
In situ is a brick mound covered with vegetation. In close vicinity of the mound stands a Ficus Religiosa (Bodhi tree) with brickwork nestled in its roots. The site is quite large.
Its historical background and period of construction are unknown. A 2007 FAD CE GIS map positions the site in geographical coordinates: 14° 20' 9.42" N, 100° 33' 39.04" E.
The two locations are about 250 meters from each other. This issue needs further research.
