Wat Khok Yai Mi or the "Monastery of the Mound of Grandmother Mi" was located on the city island in the southern area at Pratu Chai sub-district, east of Somdet Phra Sri Nakarin Park.
The monastery was situated between Khlong Chakrai Yai, a canal presently called Khlong Tho and Khlong Chakrai Noi.
There are no traces anymore visible of the monastery above ground level, although a commemoration vihara exists on the premises of the Ayutthaya Hospital.
Historical data about the monastery and its construction are unknown.
The site is indicated on Phraya Boran Rachathanin's (PBR) map drafted in 1926. The temple is situated south of what PBR mentions as Thanon Rong Krai (street). Wat Khok Yai Mi seems to have been situated on an island formed by Khlong Chakrai Yai, the present Chao Phraya River and a canal of unknown name, which ran on its northern and eastern sides; linking Khlong Chakrai Yai with the present Chao Phraya River. The temple stood though within the city walls.
