The Dau Pagoda Festival takes place every year on the 8th day of the 4th lunar month in celebration of Buddha Man Nuong, the goddess of fertility and childbirth. This is one of the most important Buddhist festivals in the delta region and Northern area of Vietnam.

Dau Pagoda is located in Thuan Thanh district, Bac Ninh province, about 30 kilometers from Hanoi. It is comprised of four pagodas: Phap Van, Phap Vu, Phap Loi, and Phap Dien, which together contain the word “Phap”, meaning “law” or “teaching”. The pagoda is at the center of a number of important historical and cultural sites in northern Bac Ninh Province, including the Luy Lau ancient citadel, Si Nhiep temple, and a system of pagodas, temples, villas, roads, markets, tombs, brick and pottery kilns.

The pagoda was built on the site of an important 3rd century Buddhist center. The current structure was constructed by Mac Dinh Chi during the 14th century and has undergone numerous renovations over the centuries. It incorporates the three-storey, 17-meter high Haa Phong Tower, which houses a large bronze bell cast in 1793, a bronze gong cast during the 18th year of the reign of Nguyen king Minh Mang (1817), and various Buddhist statues.

The Dau Pagoda Festival is a colorful and festive event that attracts pilgrims from all over Vietnam. The festivities include offerings to the Buddha, prayers for good health and prosperity, traditional music and dance performances, and a lantern procession.
