Hang Son - a temple and pagoda within a stone cave Nestled entirely within Son Cave, part of the Chu Coc mountain range in Yen Tu ward, Hang Son temple and pagoda, also known as Coc Tu, is a sacred spiritual site steeped in history and legend. Revered for its dramatic natural setting and cultural significance, it is closely associated with the myth of Bat Hai Dai Vuong, a revered sea deity, and the legendary brotherhood pact between him and National Hero Tran Quoc Tuan (Hung Dao Dai Vuong). 15:47 | 30/07/2025
