Wat Khok, or the Monastery of the Mound, was located off the city island in the southern area of Ayutthaya in the Samphao Lom Sub-district.
The temple was situated near the confluence of the Lopburi River (1) and Pa Sak River opposite Phet Fortress and in a straight view of Ayutthaya's harbour area.
Wat Nang Kui was situated in the west, while Wat Noi stood in the southeast.
The site could not be reached as it is located on private property and fenced off.
Locals in its vicinity confirmed that there were no traces of the monastery anymore above ground level.
Its historical background and period of construction are unknown.
The site is only mentioned on a Fine Arts Department map drafted in 1993 CE.
Wat Khok was in geographical coordinates: 14° 20' 46.2" N, 100° 34' 28.1" E.
Footnotes:
(1) Not many people realise the Chao Phraya River was not running on the west side of the city island in the Ayutthaya period. At that time, it was the Lopburi River that flowed around Ayutthaya. Today's Chao Phraya River ran through the Bang Ban Canal to Si Kuk and from there to Bang Sai (historical site: Chedi Wat Sanam Chai), where the Lopburi River joined the Chao Phraya River. At the time, the Chao Phraya River was situated about ten kilometres west of the centre of Ayutthaya. The city was linked to the ancient Chao Phraya River in the northwest of Ayutthaya via the Khlong Maha Phram and in the southwest via the Khlong Nam Ya. Steve Van Beeck (1994), in 'The Chao Phya: River in Transition" (Oxford University Press - New York.), writes that "It was not until 1857 that an alternative path was created [for the Chao Phraya River]. A 5-kilometre channel was dug from the entrance of Wat Chulamani to Ban Mai. The river responded by following this new course and abandoning the old one, in effect making a secondary river of the stretch that ran from Ban Mai, and into the Chao Phya Noi. Half as wide as the river above and below it, the 1857 Ban Mai shunt funnels the Chao Phya down to Ayutthaya."
