Son Hai Temple

Located beside Chuong Duong Bridge, at No. 16, Alley 53, Bach Dang Street, Son Hai Temple (whose Sino-Vietnamese name is Son Hai Linh Tu) worships National Duke and Commander-in-Chief Hung Dao Great Prince Tran Quoc Tuan. The temple is also the only place in the city that worships the four sons of Tran Hung Dao—First Prince Tran Quoc Nghien, Second Prince Tran Quoc Hien; Third, Hung Nhuong Vuong Tran Quoc Tang; Fourth Prince Tran Quoc Uat—and 18 talented generals of the Tran dynasty.

At Dong Bo Dau wharf (identified as starting at Hang Than slope and ending at Van Kiep slope), in 1284 Saint Tran organized military drills and proclaimed the Proclamation to Officers and Soldiers to encourage the patriotism of the entire army and people; it was also the place where Tran Thai Tong, Crown Prince Hoang, Tran Hung Dao, and the people of Dai Viet drove the Yuan-Mongol invaders out of Vietnam's territory and firmly maintained the nation's independence. In all three campaigns against the Yuan-Mongol invaders, the Dong Bo Dau river wharf itself was a battlefield shrouded in smoke and fire, where people fought to the death to liberate Thang Long. For this reason, the elders of Van Chai village built a temple to worship the national hero, and the soldiers of Van An village fought day and night at the river wharf for the country and the people. Those glorious feats were posthumously honored by successive kings with royal edicts. Later, due to devastation by war, the temples were destroyed, and the people of Van Chai village and local elders appointed families to preserve and keep the temple's edicts to this day. The temple was recognized as a city-level historical and cultural relic under Decision No. 3410/QD-UBND dated July 12, 2010, by the Hanoi City People's Committee.
