1. Va Temple
Va Temple, also known as Đông Cung, worships Tản Viên Sơn Thánh - the leading deity in the folk belief of Vietnam's Four Immortals.
According to legend, after helping people build mountains and control water, the Holy Tản Viên often roamed around, aiding the locals. One day, facing the rising sun, he arrived at a low hill by the Tích River. Impressed by the beauty of the place, he decided to stop and rest. At that moment, colorful clouds swiftly covered the entire area on Ba Vì Mountain. Believing it was an auspicious sign, he built a palace right there and named it Vân Già Đông Thần Cung. This location is now Va Temple. The locals, inspired by the tale of the auspicious clouds, named their village Vân Gia. From then on, the villagers prospered, taking great care in worshiping the Holy Tản Viên. The stone stele of Vân Già Đông Thần Cung, erected at the entrance of the ancestral temple, records this event and was built in the 36th year of Emperor Tự Đức's reign (1884).
Va Temple was recognized as a national historical and cultural relic by the Vietnamese government in 1964.
Location: Vân Gia Hamlet, Trung Hưng Ward, Sơn Tây Town, Hanoi
Festival: Spring festival on the 13th to 15th day of the first lunar month


2. Soc Son Temple Complex
Soc Son Temple (Soc Temple), also known as Phu Dong Thien Vuong Temple, venerates Saint Giong, the second deity in the folk belief of the Four Immortals in Vietnam. This place is deeply rooted with the legendary iron horse hoofprints of the heroic Saint Giong, symbolizing the indomitable spirit against foreign invaders.
According to the stone stele recounting the legend at the temple, after defeating the An invaders, King Hung ordered the construction of the temple to commemorate Saint Giong's contributions. The king conferred the title of deity as Dong Thien Vuong. The temple was built at the location with the iron horse hoofprints, which is the present-day Upper Temple.
The original historical site was just a small shrine dedicated to Phu Dong Thien Vuong. According to historical records, during the fight against the Song invaders, King Le Dai Hanh and his army passed by the Phu Dong Thien Vuong shrine. King Dai Hanh performed a ceremony to pray to Saint Giong for victory in the battle against the Song invaders. Indeed, in that battle, the Song army suffered a severe defeat and had to retreat to their country. Grateful and respectful of the divine spirit, King Le Dai Hanh commissioned the carving of a sandalwood tree into a worship statue and constructed the temple into a grand Soc Son Temple.
The Soc Son Temple complex comprises six architectural structures, each with its own unique historical and artistic value. These include the Upper Temple, Mother Goddess Temple, Lower Temple, Dai Bi Pagoda, Non Pagoda, and the stele area (where there is an 8-sided stone stele). The most prominent feature of this site is the statue of Saint Giong atop Da Chong Mountain (nearly 300m high with 4,000 steps), made entirely of pure copper, standing at 11.07m tall and weighing 85 tons.
The Soc Son Temple complex was designated as a national historical and cultural site by the Vietnamese government in 1962.
Location: Located on Ve Linh Mountain (Soc Mountain) in Phu Linh hamlet, Phu Linh commune, Soc Son district, Hanoi
Festival: The Soc Son Giong Festival takes place from the 6th to the 8th day of the 1st lunar month every year.
