Wat Hip, or the Monastery of the Chest, was located on Ayutthaya's city island, east of the Somdet Phra Sri Nakharin Park and part of the Ayutthaya Historical Park in the Pratu Chai Sub-district.
The site is first indicated on a 19th-century map on the east bank of Khlong Chakrai Yai, south of Wat Som Noi (Wat Som) and northeast of Wat Phram (Wat Jao Phram) on the opposite side of the canal.
Wat Hip must have been located approximatively in geographical coordinates: 14° 20' 40.4" N, 100° 33' 25.1" E.
Phraya Boran Ratchathanin [PBR] situates Wat Hip also on the east bank of Khlong Chakrai Yai, south of Wat Som, but southeast of Wat Ubosot, while on its east stood Wat Khok Khemi and Wat Khok Khema. The temple was situated north of what PBR mentions as Thanon Rong Krai. This position is about 250 meters more to the south than Wat Hip’s position on the 19th-century map and matches more or less with Wat Pa Fuk on the latter.
The conclusion of above is that the location of Wat Hip is different on both maps.
The Fine Arts Department followed PBR’s map regarding the position of Wat Hip and excavated the area in geographical coordinates: 14° 20' 31.68" N, 100° 33' 25.27" E (the corner of present Khlong Tho Road and Soi Khlong Tho 4). Apparently, some brickwork was found.
Historical data about the monastery and its construction are unknown.
I put the location for Wat Hip opposite Wat Jao Phram and considered the site excavated by the FAD opposite Wat Jao Phrap as Wat Pa Fuk.
