Originally, Wat Phra Ngam was a royal temple that was later elevated to the status of a royal monastery by His Majesty the King on April 22, 1996. Inside the temple, there are large ruins of a stupa believed to have been constructed during the Dvaravati period in the 11th or 12th century, extending to the 16th century, similar to Phra Pathom Chedi, Phra Prang of Wat Phra Protnheang Worawihan, and Wat Thung Phra Meru in the Ananta Garden area. During a visit to various temples, His Holiness Somdet Phra Mahasamana Chao Krom Phra Wachirayan Voravirot, the Supreme Patriarch, remarked that Wat Phra Ngam might have been established around the same time as Nakhon Pathom when it served as the capital of Dvaravati. This is supported by the ancient artifacts discovered in the area, which are all ancient Dvaravati items. Similar findings, including a bronze Buddha statue and beautiful earthenware, were excavated in the vicinity of Phra Pathom Chedi. The beauty of these artifacts is exceptional and hard to find elsewhere. They are currently preserved at the National Museum, while some broken pieces are kept at the Phra Pathom Chedi Museum. Wat Phra Ngam fell into disrepair over time due to changes in the surrounding area and later prospered with the establishment of a new city. Subsequently, during the reign of King Rama IV of Rattanakosin, he ordered craftsmen to renovate Phra Pathom Chedi. This was prompted by his experience during his monkhood when he visited and meditated on the northeastern side of Phra Pathom Chedi, where he witnessed a miraculous light. He was convinced that this stupa was the site containing sacred relics and thus directed improvements to be made, transforming Phra Pathom Chedi into the magnificent landmark that it is today.
