Bac Ninh, also known as Kinh Bac region, is considered the most sacred ancient land in Vietnam, the ancestral land of Vietnam Buddhism, the homeland of Ly Dynasty and also the main town in the north of former Thang Long, Hanoi. Talking about Bac Ninh, people often think about its famous ancient temples such as Dau Pagoda, But Thap Pagoda, Phat Tich Pagoda and Kinh Duong Vuong Temple. Located in the Red River Delta of the northern part of the country, the province's name derives from Sino-Vietnamese "northern serenity". Bac Ninh is rich in culture and is known nationally for Quan họ folk music. Quan ho was recognised as the Intangible Cultural Heritage by the UNESCO in 2009.
