Founding period: The pagoda was initiated and founded in the first year of Hong Duc (1470), during the reign of King Le Thanh Tong. This historical evidence is corroborated by the ancient stone stele "Thien Phuc Tu bi ky" preserved at the relic site.
History of repairs: The pagoda has a history of continuous restoration through dynasties. Ancient inscriptions record a major reconstruction in the first year of Canh Hung (1740), initiated by Royal Concubine Tran Thi Ngoc. In the Nguyen period, the structure continued to undergo major renovations in the first year of Thanh Thai (1889), the reign of King Khai Dinh (1918), and the reign of King Bao Dai to preserve its spacious and imposing appearance.
Worship significance: The pagoda worships Buddha according to Mahayana Buddhism, guiding people toward compassion, encouraging good and deterring evil, educating benevolence and righteousness, and closely linking with the spiritual life of village residents.
Revolutionary imprint: During the period of secret pre-uprising activities and the resistance war against the French colonialists, Dong Duong Pagoda was a base for sheltering and safely protecting many high-ranking revolutionary cadres of the Party and State, such as comrades Do Muoi, Hoang Quoc Viet, Van Tien Dung, Nguyen Van Loc....
