TL;DR: Bạch Mã Temple on Hàng Buồm Street in Hanoi is the eastern guardian temple of the Thăng Long Tứ Tran system, dedicated to the deity Long Đỗ, the original spirit of the land of Thăng Long. Legend holds that the god appeared as a white horse to help King Lý Thái Tổ build the citadel, and was thereafter honored as tutelary god of the whole capital. The temple was ranked a Special National Relic in 2022, and its festival is held on the 12th and 13th of the second lunar month each year.
What is Bạch Mã Temple and why is it called the Eastern Guardian?
Bạch Mã Temple is an ancient temple at 76 Hàng Buồm Street, Hoàn Kiếm District (before July 2025), Hanoi. It worships the deity Long Đỗ, the guardian spirit of the Thăng Long capital, guarding the East within the Thăng Long Tứ Tran (Four Guardian Temples of Thăng Long) system. Among the four temples guarding the four directions of the capital, Bạch Mã Temple is considered the oldest and the one dedicated to the most important deity.
According to Nhân Dân newspaper and the Vietnam News Agency, Thăng Long Tứ Tran comprises four temples worshipping four deities in four directions to protect the Thăng Long capital:
| Guardian direction | Temple name | Deity worshipped | Present location |
|---|---|---|---|
| East | Bạch Mã Temple | Deity Long Đỗ | Hoàn Kiếm District (before July 2025) |
| West | Voi Phục Temple | Deity Linh Lang Đại Vương | Ba Đình District |
| South | Kim Liên Temple | Deity Cao Sơn Đại Vương | Đống Đa District |
| North | Quán Thánh Temple | Deity Huyền Thiên Trấn Vũ | Ba Đình District |
This division shows that the worship of guardian deities of the directions is a cultural layer predating the founding of the Thăng Long capital, but when Lý Thái Tổ moved the capital here, that system was reorganized to serve a new center of power. Bạch Mã Temple sits in the East, the direction of growth and also the direction of the main traffic axis in the old quarter, near the Red River and the old boat wharves.
Who is the deity Long Đỗ and why was he honored as tutelary god of the capital?
The deity Long Đỗ is the original spirit of the land of Thăng Long, worshipped before the capital was established. The name "Long Đỗ" is tied to the image of the navel of the land, where the vital energy of heaven and earth converges. Legend holds that when King Lý Thái Tổ moved the capital to Thăng Long, the citadel kept collapsing as it was built, so the king came to the temple to pray to Long Đỗ. From within the temple, a white horse walked out. The king followed the horse's hoofprints to build the citadel and succeeded, so he honored the deity as tutelary god of the Thăng Long capital.
This event explains why the temple bears the name Bạch Mã, meaning white horse. The white horse in the legend is not merely a fantastical detail but a symbol of guidance, of the link between the divine and the work of nation-building. King Lý Thái Tổ's active visit to pray to Long Đỗ shows that the new court sought to connect with indigenous belief to consolidate its legitimacy.
Later dynasties followed suit, conferring on the deity the title Quảng Lợi Bạch Mã toi linh thuong dang than. This title shows the special status of Long Đỗ within the capital's pantheon. More than a village deity, Long Đỗ was regarded as tutelary god of the entire capital, a distinctly higher level of belief.
Why did a local deity become the tutelary god of the whole capital?
This is the central question of Thăng Long belief. When a new dynasty chose a land as its capital, it did not only build palaces and ramparts but also had to establish relations with indigenous spiritual forces. Long Đỗ was the deity who had reigned over this land before, so acknowledging and honoring him was a way to legitimize the court's power over a new land.
On the other hand, the difficulty in building the citadel was explained by divine intervention. When King Lý Thái Tổ prayed and was helped by the deity, the relationship between royal power and divine power was established. Long Đỗ went from a deity of one land to patron deity of the entire capital, and Bạch Mã Temple became the state's official place of worship.
What notable architecture and artifacts does Bạch Mã Temple have?
Bạch Mã Temple today bears the distinctive features of Nguyen dynasty architecture on a fairly large scale, facing South. The structures are harmoniously arranged along a vertical axis, including the nghi mon (ceremonial gate), phuong dinh (square pavilion), dai bai (main hall), cung cam (forbidden sanctuary), thieu huong (incense burner), and the hoi dong house at the rear.
Over more than 1,000 years, the temple has been restored many times but still retains its solemn landscape and rare ancient traces. It currently preserves many precious artifacts of great historical value:
- Stele inscriptions recording the legends, myths of the temple's construction and rituals of worship, and renovations over more than 1,000 years
- Imperial edicts of various dynasties
- Altars, vases, and pedestals
- Bronze bells and palanquins
These artifacts are not only of artistic value but also precious materials for studying the history of belief and court ritual through the periods. According to the Vietnam News Agency, through the Ly, Tran, and Le dynasties with 52 kings who established the capital at Thăng Long, Bạch Mã Temple is the place that most fully witnessed the formation and development of ancient Thăng Long and today's Hanoi Capital.
When is the Bạch Mã Temple festival held and what is special about it?
The Bạch Mã Temple festival is held on the 12th and 13th of the second lunar month each year. It is a blend of folk belief culture and court ritual, creating a distinctive character. This combination reflects the temple's special status: both a place of worship for the old quarter community and a venue for official rituals of the feudal state.
The rituals in the festival typically include palanquin processions, incense offerings, and folk cultural activities. The festival's continuation to this day shows the vitality of Long Đỗ worship in contemporary life, even though its political function has changed over time.
Why was Thăng Long Tứ Tran recognized as a Special National Relic?
On January 18, 2022, the Prime Minister signed Decision No. 93/QD-TTg ranking five relics nationwide as Special National Relics, including the Historical and Architectural-Artistic Relic of Thăng Long Tứ Tran. This cluster comprises Bạch Mã Temple, Voi Phục Temple, Quán Thánh Temple, and Kim Liên Temple.
This recognition affirms the typical historical and belief values of the relic complex in Hanoi Capital. According to the Vietnam News Agency, Thăng Long Tứ Tran is tied to the birth of the Thăng Long Capital in the Ly era, worshipping four deities guarding the four vital directions, protecting day and night so that ancient Thăng Long Citadel and today's Hanoi Capital remain peaceful.
On the evening of June 18, 2022, at Bạch Mã Temple, the Hoàn Kiếm District (before July 2025) People's Committee held a ceremony to receive the Special National Relic recognition certificate. Representatives of Hoàn Kiếm District (before July 2025) leadership pledged to continue promoting conservation solutions and enhancing the value of Bạch Mã Temple.
What role does Bạch Mã Temple play in Hanoi's cultural life today?
Today, Bạch Mã Temple is not only a spiritual destination but also an important part of the Capital's cultural heritage system. Mr. Phạm Tuấn Long, Chairman of the Hoàn Kiếm District (before July 2025) People's Committee, said Bạch Mã Temple receives attention from city and district authorities for conservation and promotion of the relic's values to serve research on history and culture and to become a distinctive tourist destination for domestic and foreign visitors.
Hoàn Kiếm District (before July 2025) is also focusing resources on site clearance for dozens of relics, relocating hundreds of households with over 2,000 people, and conserving relic structures in the area. At the same time, the district mobilizes social resources to promote intangible heritages, restore craft streets, and organize traditional festivals in the old quarter and around Hoàn Kiếm Lake.
These efforts show that Bạch Mã Temple is not frozen in the past but continues to participate in contemporary life, both as a space of belief and as a resource for tourism and cultural-economic development.
