Wat Mai is a vanished temple formerly located on Ayutthaya's city island in present Pratu Chai sub-district, in the vicinity of an area formerly called Laem Sarapha.
Making an assessment off all the monastic structures, in the zone demarcated by Chikun Rd, Pa Thon Rd, Pridi Banomyong Rd and U-thong Rd is rather difficult, as the position and name of the structures varies on different maps. On a 19th century map there are 15 structures counted, while on the 20th century PBR map there are 13 mentioned. There is inconsistence in the names and the positions. Even a map drafted in the 90's by the Fine Arts Department, what I presume, based on excavations in the zone, shed no light on this matter. Positions of monastic structures can be asserted, but their ancient names will remain questioned forever.
