Located in Hien Luong, the temple honors Au Co, a central figure in Vietnamese origin mythology. According to legend, Au Co married Lac Long Quan and gave birth to a pouch of one hundred eggs, from which one hundred sons emerged. This story symbolizes the shared ancestry of the Vietnamese people and underpins the enduring tradition of honoring Au Co as the nation’s ancestral mother. The temple was established during the Later Le Dynasty and was recognized as a national historical and cultural relic in 1991.
The temple’s main sanctuary houses a revered wooden statue of Mother Au Co, dating to the 19th century and recognized as a National Treasure of Vietnam in 2020. The site remains an important center of spiritual life, particularly during the annual festival held around the seventh day of the first lunar month, when pilgrims gather to offer incense and participate in traditional ceremonies. A visit offers insight into Vietnam’s beliefs about ancestral origins, filial gratitude and cultural continuity.
