Wat Chong Lom (1) was situated off the city island in the northern area of Ayutthaya, in the Phukhao Thong Sub-district. The monastery stood on the east bank of Maenam Ban Pom (2), the Chao Phraya River and south of Khlong Maha Nak. (3) The temple stood southeast of Wat Chang Thong (defunct), on the edge of the Phukhao Thong Plains.

In situ are the remains of a wall of the former monastery as some other brickwork spread over the area. The remaining wall is situated between houses and still shows some stucco work.

Wat Chong Lom figures in the Royal Chronicles of Ayutthaya. It was in the vicinity of this monastery (4) that Prince Naresuan (reign 1590-1605 CE) and his brother Prince Ekathotsarot (reign 1605-1610/11 CE) set up an army camp after having attacked the rear guard of the retreating forces of the Burmese Maha Uparat at Bang Kradan. Forces were gathered here starting on Wednesday, the first day of the waxing moon of the month of July 1586 CE. Big guns were lowered and fixed into junks, and after a week of preparation, Prince Naresuan attacked the camp of the King of Hongsawadi, Nanda Bayin (reign 1581-1599 CE), set up in the fields north of Ayutthaya. The Burmese camp was so heavily bombarded that the King of Hongsawadi had to break up his camp and order a retreat towards Pa Mok. [1]

“On Wednesday, the first day of the waxing moon of the seventh month, the Kings proceeded forth to establish their victory army in the vicinity of Chòng Lom Monastery. On Thursday, the eighth day of the waxing moon of the seventh month, the Phra Marüttayurat gun was loaded onto a junk and taken up to fire on the King of Hongsawadi’s stockade at the Pak Khu customs house. The King of Hongsawadi, seeing that the inhabitants of the Royal Metropolis had brought a great gun loaded on a junk and were able to reach the stockade with its fire, withdrew his army and encamped at Pa Mok Yai.” [2]

Historical data about the monastery and its construction is unknown.

Wat Chong Lom shows on Phraya Boran Rachathanin's map drafted in 1926 CE and features on 1974, 1993 and 2007 CE Foreign Arts Department (FAD) maps. Phraya Boran (1871-1936 CE) was the Superintendent Commissioner of Monthon Ayutthaya from 1925 to 1929 CE but occupied important functions since 1896 CE in Monthon Ayutthaya.

(3) Khlong Maha Nak is situated off Ayutthaya's city island in the northern area, in the Phukhao Thong Sub-district. The canal was dug during the period of the Siamese-Burmese war of 1563-1564 CE called the "White Elephant War". The Maha Nak Canal ran from Wat Pa Phlu towards Khlong Phukhao Thong.
