Wat Khok, or the Monastery of the Mound, was located off the city island in the eastern area of Ayutthaya in the Hantra Sub-district.
The temple was south of Khlong Hantra (1) on the east bank of a now-defunct canal leading to the latter. Wat Pa Kho stood northwest, while Wat Dusittharam was southeast.
There are no traces anymore of the former monastery.
Historical data about the monastery and its construction are unknown.
The site is indicated on 1974 and 2007 CE Fine Arts Department maps but is missing on the 1993 CE FAD map.
Wat Khok was in geographical coordinates: 14° 22' 19.53" N, 100° 35' 10.77" E.
Footnotes:
(1) Khlong Hantra flows through the sub-district of the same name and is formerly referred to as Thung Hantra or Hantra Fields. This canal was once a stretch of the Pa Sak River, meandering around the former Ban Ma (Horse village) east of Ayutthaya. When the latter was diverted towards the Front city moat at some stage, the old riverbed was divided up into different canals: Khlong Hantra (from Wat Pa Kho till Wat Krasang), Khlong Kramang (from Wat Krasang till the entry of Khlong Doem), Khlong Dusit (called after Wat Dusit on its west bank) and Khlong Khao San (with its mouth at the present Pa Sak River, being the southern end of the former Front moat). Khlong Hantra was one of the most important former canals, east of Ayutthaya, bordering the ancient Ayothya area.
