Wat Prasat or the "Monastery of the Castle (Tower)" was located on the city island in the southern area at Pratu Chai sub-district, east of the Somdet Phra Sri Nakharin Park.
The monastery was situated between Khlong Chakrai Yai, a canal presently called Khlong Tho and Khlong Chakrai Noi. It stood along one of the most important streets of the city, being the Maha Rathaya Street also called Thanon Luang, a laterite paved road, about 12 meters wide, which ran through the center of the capital and linked the Royal Palace with the southern city gate. Wat Prasat was located west of the temple cluster made by Wat Khok Khemi, Wat Khok Khema and Wat Khok Yai Mi.
The remnants of the temple stands on what is now the Ayutthaya Hospital. Only a large octagonal base of a chedi in the classic Ayutthayan style and its toppled part are visible.
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 north of what PBR mentions as Thanon Rong Krai (street).
