Uong bi: Yen Tu historical relic and scenic spot located in Uong Bi ward, Quang Ninh province, was ranked as a special national relic in 2012 and in 2025 was recognized by the World Heritage Committee, UNESCO as a World Cultural Heritage. The beauty of Yen Tu is the grandeur and tranquility of the mountains and forests mingled with the serenity and ancientness of the system of pagodas, towers, and Zen realms.

According to Vietnam News Agency, Yen Tu has become a Buddhist centre of Vietnam since King Tran Nhan Tong gave up the throne, put on a monk’s robes, and established a typical Buddhist sect of Vietnam, namely Truc Lam Zen Buddhism. He built hundreds of large and small works on Yen Tu Mountain as places for practicing and preaching Buddhism.

The noble cultural and historical values of Yen Tu open up opportunities to develop tourism to reach international level.
