Walking up from the foot of the mountain, the first thing that catches the eye is not a towering triple-arched gate, but an earthen wall. Rammed from compacted earth mixed with broken bricks, roof tiles, and earthenware funerary urn shards, the wall runs along the hillside for nearly four hundred meters, standing about two meters at its lowest points and up to five meters at its highest. Behind that earthen wall stand nearly one hundred interconnected bays roofed with weathered handmade tiles, and farther behind lies a hillside garden densely packed with brick stupas.
This is Bổ Đà Pagoda on the slope of Phượng Hoàng Mountain (also called Bổ Đà Mountain), whose main monastery bears the Sino-Vietnamese name Tứ Ân tự (Four Gratitudes Pagoda), known locally as Chùa Bổ or Chùa Ông Bổ. The site preserves two treasures rarely found together at any other temple, namely an almost intact set of Buddhist sutra woodblocks carved on persimmon wood (gỗ thị) and a stupa garden holding the relics of more than twelve hundred monks and nuns who practiced here across generations. Both speak to a single theme, the lineage transmission of a monastic mountain school (sơn môn).
INames and Buddhist lineage
This monastic complex carries several names tied to different historical layers. Its full name after the mountain and the ancient shrine on the peak is Bổ Đà Sơn Quán Âm tự (Avalokiteshvara Pagoda of Bổ Đà Mountain). Tứ Ân tự is the formal literary name of the great monastery expanded in the 18th century at the mountain base. Locals call it Chùa Bổ, Chùa Ông Bổ (tied to the legend of the woodcutter), or Chùa Tam Giáo (Pagoda of the Three Teachings, because its main hall venerates the Buddha, Confucius, and Laozi together). The Chinese characters at the top of this page represent the literary name Tứ Ân tự.
Tứ Ân refers to the Four Gratitudes in Buddhist teaching that practitioners must remember, namely gratitude to parents, gratitude to sentient beings, gratitude to the nation, and gratitude to the Three Jewels. Naming the monastery after the Four Gratitudes declares right at the outer gate that spiritual practice here is inseparable from repaying kindness. Meanwhile, Bổ Đà is a vernacular pronunciation of Phổ Đà (Mount Potalaka), the scriptural mountain regarded as the sacred abode of Bodhisattva Avalokiteshvara (Quán Thế Âm). Bestowing that scriptural mountain name upon the Phượng Hoàng hill range on the north bank of the Cầu River was how early generations anchored a sacred Buddhist geography onto their own homeland.
A distinctive feature in the sanctuary arrangement of Tứ Ân Pagoda is the spirit of harmonizing the Three Teachings (Tam giáo đồng nguyên). Alongside Mahayana Buddha statues, Bodhisattva Avalokiteshvara, and the Three Patriarchs of Trúc Lâm (Trúc Lâm Tam Tổ), the main hall also houses statues of Confucius (Khổng Tử) and Laozi (Lão Tử), while the complex includes a shrine dedicated to Thạch Linh Thần Tướng (a mountain spirit linked to ancient legends of defending the country against foreign invaders).
Regarding lineage, the heritage dossier of the Department of Cultural Heritage states that Bổ Đà Pagoda primarily follows the Lâm Tế (Linji) Zen school, which spread into this region in the late 17th and early 18th centuries. Research published on Phật Sự Online likewise affirms that the Bổ Đà monastic school served for centuries as a major ordination and training center of the Lâm Tế Zen lineage in the Kinh Bắc region.
At the same time, several other accounts describe Bổ Đà Pagoda as a major Buddhist center associated with the Trúc Lâm Yên Tử Zen school, noting that the Three Patriarchs of Trúc Lâm are venerated inside the pagoda. Scholars explain these two descriptions through two historical layers, noting that the Kinh Bắc region lay within the sphere of influence of Trúc Lâm Zen from the Trần dynasty, and when Lâm Tế Zen masters arrived in the 18th-century Restored Lê period, they harmonized both Zen streams and preserved texts from both the Lâm Tế and Trúc Lâm lineages. In July 2025, Bổ Đà Pagoda was also inscribed by UNESCO as a component site of the Yên Tử - Vĩnh Nghiêm - Côn Sơn, Kiếp Bạc Complex of Monuments and Landscapes.
A common misconception surrounds the term ancestral seat (chốn tổ). Hearing that Bổ Đà is an ancestral seat, some visitors assume the entire Lâm Tế Zen school originated here. That is not the case. Here, chốn tổ means the head monastery of a monastic mountain network (sơn môn Bổ Đà), a network of branch pagodas sharing a common transmission line that sent novices here to receive ordination and study sutras, and brought their relics back to the stupa garden after they passed away. The vast size of the stupa garden is the direct result of that head-monastery role, not proof that the pagoda is older than all others.
IITwo chronological layers
When speaking of the age of Bổ Đà Pagoda, it is essential to separate two chronological layers, because conflating them causes most misunderstandings about the site.
The first layer is the legendary date. The heritage dossier records that according to oral tradition the pagoda dates back to the Lý dynasty, around the 11th century, associated with the Avalokiteshvara shrine (Chùa Cao) near the mountain peak. Local folklore tells of a poor woodcutter surnamed Bùi who was deeply filial to his aged mother. One day, while chopping into an old pine stump on the mountain, thirty-two gold coins suddenly sprang out, corresponding to the thirty-two manifestations of Bodhisattva Avalokiteshvara. After receiving a dream omen and praying for a son, whom he named Tất Đạt, he built a small hermitage on the peak dedicated to Child-Giving Avalokiteshvara (Quán Âm Tống Tử), and villagers called him Ông Bổ (Mr. Woodcutter) and named the mountain Ông Bổ Mountain. That story belongs to folk tradition without contemporary textual verification.
The second layer is the date of the standing structures. The entire architectural complex visitors see today, including Tứ Ân Pagoda, Tam Đức Hermitage, the rammed-earth walls, the stupa garden, and most of the statues, was expanded and shaped during the Restored Lê dynasty (Lê Trung Hưng) in the 18th century and maintained into the Nguyễn dynasty. According to temple records, under King Lê Dụ Tông (Bảo Thái reign, 1720 - 1729), Founding Master Phạm Kim Hưng led a major restoration of Quán Âm Pagoda. Later, under King Lê Hiển Tông (Cảnh Hưng reign, 1740 - 1786), the second patriarch of the monastic school, Zen Master Tính Ánh (surnamed Ngô, Dharma name Ngô Tuệ Không, posthumous title Most Venerable Hảo Tiết), founded and built Tứ Ân Pagoda and Tam Đức Hermitage at the foot of the mountain. The prized persimmon-wood sutra blocks in the pagoda were likewise carved beginning in the Lê Cảnh Hưng era (with dated blocks spanning from around 1740, 1741, and 1744 into the early 20th century). In short, this is an 18th-century monastic complex standing on a mountain whose legendary roots reach back to the 11th century. Both layers deserve recognition, but they should not be merged into one.
- 11th centuryLegendary founding dateAccording to oral tradition, a shrine to Avalokiteshvara (Chùa Cao) was erected on Bổ Đà Mountain under the Lý dynasty, linked to the tale of the woodcutter surnamed Bùi. Official dossiers explicitly label this layer as legendary.
- 1720 - 1729Restoration by Founding Master Phạm Kim HưngDuring the Bảo Thái reign of King Lê Dụ Tông, Founding Master Phạm Kim Hưng carried out a major restoration and expansion of the ancient pagoda on Bổ Đà Mountain.
- Mid-18th centuryZen Master Tính Ánh builds Tứ Ân PagodaDuring the Cảnh Hưng reign of King Lê Hiển Tông (1740 - 1786), Zen Master Tính Ánh (Ngô Tuệ Không) founded Tứ Ân Pagoda and Tam Đức Hermitage, establishing the scale of the Bổ Đà monastic seat.
- From the 1740sCarving of the persimmon-wood sutra blocksThe collection of Buddhist sutra woodblocks on persimmon wood began to be carved under the Lê Cảnh Hưng reign (sources cite 1740, 1741, or 1744) and was supplemented through the Nguyễn dynasty into the early 20th century.
- 18th - 19th centuriesCompletion of earthen walls and stupa gardenThe 92-bay interconnected monastery, enclosing rammed-earth walls, and stupa garden for generations of monks and nuns were built and restored across the Restored Lê and Nguyễn periods.
- 1992National heritage siteThe Bổ Đà Pagoda complex was designated a national historical and cultural heritage site.
- 2016Special national heritage siteDesignated a special national heritage site under Decision No. 2499/QĐ-TTg dated December 22, 2016.
- 2017 and 2025National Treasure and UNESCO World HeritageIn 2017, the Bổ Đà Festival was inscribed as national intangible cultural heritage (Decision No. 217 dated January 23, 2017) and the woodblock collection was recognized as a National Treasure (Decision No. 2089/QĐ-TTg dated December 25, 2017). In July 2025, Bổ Đà Pagoda was inscribed by UNESCO as part of the Yên Tử - Vĩnh Nghiêm - Côn Sơn, Kiếp Bạc World Heritage complex.
IIIRammed-earth walls, stupa garden, and woodblocks
The entire heritage complex covers roughly 51,784 square meters, divided into three zones comprising an outer orchard and forest area of about 31,000 square meters, the main monastery compound of about 13,000 square meters, and the stupa garden of about 7,784 square meters. Because the monastery hugs the slope of Phượng Hoàng Mountain (Bổ Đà Mountain), its rows of halls step upward along the gradient rather than sitting on a single flat terrace.
Rammed-earth walls and the internally connected, externally enclosed layout
What sets Bổ Đà Pagoda apart from contemporary northern Vietnamese pagodas is its material. The perimeter walls are built not of fired brick, but of rammed red-gravel earth mixed with broken bricks, roof tiles, and shards of Thổ Hà stoneware funerary urns resting on a laterite footing. The heritage dossier records the enclosing earthen wall as nearly 400 meters long, standing 2 to 5 meters high and about half a meter thick. The roof tiles and floor bricks were also hand-fired locally, giving the entire compound a unified earthen-brown tone.
The architectural plan follows the internally connected, externally enclosed (nội thông ngoại bế) style. The heritage dossier records that the Tứ Ân Pagoda compound comprises 16 buildings with 92 interconnected bays linked by covered corridors and interior courtyards, allowing one to walk from one end of the monastery to the other without stepping outdoors. That layout suited the function of an ancestral monastic seat, designed first and foremost as a place of residence and study for the monastic community.
The stupa garden
The stupa garden lies on the hillside to the left (northwest) of the main monastery. Built of fired brick and blue stone and arranged in terraced rows along the slope, each stupa has a sealed base, with a nectar vase crowning the stupas of monks and a lotus bud crowning the stupas of nuns. Each stupa enshrines the cremated relics and ashes of one or several monastics who practiced within the Bổ Đà mountain school.
Published figures for the stupa garden and the woodblock collection vary across sources and are stated here directly. Regarding the number of stupas, the Department of Cultural Heritage dossier records 110 stupas and ancient tombs of various sizes (including 97 named or unnamed ancient brick stupas), a VietnamPlus report cites 107 stupas, and several other articles cite 102 stupas. Regarding stupa garden area, the dossier records nearly 8,000 square meters while other sources specify 7,784 square meters. Regarding the number of monks and nuns enshrined, the dossier records 1,214 monastics while VietnamPlus records over 1,218. Regarding the number of woodblocks, the Department of Cultural Heritage dossier and Phật Sự Online record 1,935 blocks, VnExpress cites 1,953 blocks or nearly 2,000 blocks, and some articles write over 2,000 blocks. The library records the figures from each source rather than choosing one arbitrarily.
The persimmon-wood sutra blocks
This is the treasure that makes Bổ Đà Pagoda unmistakable. The woodblocks began to be carved under the Lê Cảnh Hưng reign (sources cite 1740, 1741, or the earliest explicitly dated block in the 5th year of Cảnh Hưng, 1744) and continued to be supplemented until 1930. Carved in reverse relief in Chinese, Nôm, and Sanskrit scripts, their contents cover Mahayana sutras, monastic discipline (Vinaya) codes, and liturgical manuals such as the Surangama Sutra (Kinh Lăng Nghiêm Chính Mạch), Karmavacana manual (Kinh Yết Ma Hội Bản), Records of the Southern Sea (Nam Hải Ký Quy), Universal Gate Chapter of Avalokiteshvara (Quán Thế Âm Bồ Tát Phổ Môn Phẩm), and Diamond Sutra (Kim Cương Bát Nhã Ba La Mật Kinh), alongside ordination rules and lineage records of the Lâm Tế and Trúc Lâm Zen schools.
The blocks are made of persimmon wood (gỗ thị), a pale, fine-grained, flexible wood resistant to warping and woodborers, ideally suited for carving small, intricate characters. Typical blocks measure about 50 to 60 centimeters long, 25 to 30 centimeters wide, and around 2.5 centimeters thick, and are stored on wooden racks inside the archive room. The collection was recognized as a National Treasure under Decision No. 2089/QĐ-TTg dated December 25, 2017.
The main architectural compound of 16 buildings with 92 interconnected bays (Three Jewels hall, Patriarch hall, front hall, monks' quarters, guest hall, corridors). Beside Tứ Ân Pagoda stands Tam Đức Hermitage, built in the Restored Lê period to venerate the founding patriarchs of the monastic school.
A small temple near the summit of Phượng Hoàng Mountain (Bổ Đà Mountain) worshipping Child-Giving Avalokiteshvara, tied to the Lý-era legend of the woodcutter surnamed Bùi.
A shrine dedicated to Thạch Linh Thần Tướng, the tutelary spirit of Bổ Đà Mountain credited in legend with helping defend the country, commemorated on the 12th day of the 9th lunar month.
Perimeter walls of compacted earth mixed with broken bricks, red gravel, and stoneware urn shards, nearly 400 meters long and 2 to 5 meters high, preserving a rustic centuries-old appearance.
A hillside stupa compound covering about 7,784 square meters with roughly one hundred brick and stone stupas enshrining the relics of over twelve hundred monks and nuns.
IVThe lie of the land and orientation
This section presents the library's reading through the lens of traditional feng shui, not content recorded on stone steles or in official heritage dossiers. The library states this clearly so visitors can distinguish documentary records from geomantic interpretation.
The pagoda sits against Phượng Hoàng Mountain (Bổ Đà Mountain) and faces the alluvial plains along the north bank of the Cầu River. In traditional geomancy, this exemplifies the classical configuration of sitting on mountain and facing water (tựa sơn hướng thủy) in a complete and legible form, which is fairly rare among northern lowland pagodas that lack real hills and must rely on earthen mounds or ponds instead. At Bổ Đà both elements are present, with the pine-covered mountain serving as the backrest hill (hậu chẩm) behind and the Cầu River acting as the water vein channeling qi in front.
Even more telling is the sloped terrain. Rather than leveling the hillside into a single flat platform, the builders stepped the rows of halls upward along the grade, mirroring the graduated stages of monastic study and cultivation from low to high. In practical terms, this stepped slope is equally sound, because rainwater drains rapidly down the incline so the hall floors never stay damp, allowing the persimmon-wood sutra blocks to survive for nearly three hundred years without rotting.
Through the lens of feng shui, the rammed-earth wall acts as an outer protective ring, just tall enough to break the wind and enclose a distinct field of qi. Combined with the internally connected, externally enclosed layout inside, the entire monastery functions as a vessel that gathers qi, allowing energy to enter and circulate gently through the interior courtyards and corridors rather than rushing straight out. This is the spatial design of a long-term monastic training ground, not a roadside shrine built merely for brief visits.
Finally, there is the stupa garden. The stupa compound rests on the adjoining hillside at an elevation higher than most of the main monastery. In classical geomancy, a high, dry, and quiet slope suits a place of eternal rest for accomplished practitioners. Placing past generations of patriarchs on higher ground watching over the monks practicing below sets monastic transmission in its proper place.
VBổ Đà Pagoda festival
The Bổ Đà Pagoda festival takes place in the second lunar month as the largest annual gathering in the region, inscribed on the national list of intangible cultural heritage under Decision No. 217/QĐ-BVHTTDL dated January 23, 2017.
One discrepancy in dates across official sources should be noted. The monument dossier on the Department of Cultural Heritage website states that the festival runs from the 15th to the 18th of the second lunar month, whereas the intangible heritage festival dossier on the same website lists the main festival from the 16th to the 18th of the second lunar month (and some news reports cite the 16th to the 19th). The library records both. What all sources agree on is that the 17th of the second lunar month is the death anniversary of the Founding Patriarch and the 18th of the second lunar month is the main festival day.
| Lunar date | Ritual | Activities |
|---|---|---|
| Before the 16th of the 2nd lunar month | Preparing offerings and statue cleansing | Surrounding villages prepare offerings while the monastery opens its gates on the 15th and cleanses the statues and ritual vessels (lễ bao sái). |
| 16th and 17th of the 2nd lunar month | Festival opening and Patriarch memorial | Incense offerings at Tứ Ân Pagoda, as monks and nuns from branch temples across the Bổ Đà monastic network return to observe the memorial day of the Founding Patriarch and chant sutras. |
| 18th of the 2nd lunar month | Main festival day and Buddha offering | On the morning of the main day, the monastic assembly performs the grand offering to the Buddha at the Three Jewels hall, followed by village palanquin and offering processions accompanied by flag teams, drum troupes, and ritual officiants. |
| During the festival | Traditional Quan họ folk singing | Because the Vân Hà - Tiên Sơn area belongs to the ancient Quan họ cultural zone on the north bank of the Cầu River, Quan họ singing contests and exchanges are a signature feature of the festival. |
| 12th day of the 9th lunar month | Memorial of General Thạch Linh | The second annual observance at the complex, honoring the tutelary spirit of Bổ Đà Mountain at Thạch Tướng Temple. |
One aspect of this gathering stands out. The Bổ Đà Pagoda festival is not simply a lowland agricultural village festival, but first and foremost the annual convocation of a monastic mountain network (sơn môn), when monks and nuns from branch temples across many provinces return to pay homage to their patriarchs at the ancestral seat. The village palanquin processions and Quan họ singing represent the communal cultural layer woven around that monastic core.

Because this is an active monastic training center rather than a museum, temple etiquette must be observed. Visitors are reminded to dress modestly, remove hats when entering interior halls, walk and speak quietly near the monks' quarters and Patriarch hall, and never touch the woodblocks. The stupa garden holds the relics of generations of patriarchs, so please stay on the paved paths and do not climb onto stupa bases. The rammed-earth walls are original structures nearly three hundred years old, so please do not lean on or climb them.

?Quick Questions
Who is worshipped at Bổ Đà Pagoda
The pagoda worships the Buddha according to Northern Buddhism, with the main sanctuary at Tứ Ân Pagoda arranged in the spirit of harmonizing the Three Teachings (Tam giáo đồng nguyên), enshrining Mahayana Buddhas, the Three Patriarchs of Trúc Lâm, Confucius, and Laozi. The complex also includes Tam Đức Hermitage and the Patriarch hall honoring patriarchs of the Bổ Đà monastic school, High Pagoda (Chùa Cao) on the peak worshipping Child-Giving Avalokiteshvara, and a shrine to Thạch Linh Thần Tướng.
Which Zen school does Bổ Đà Pagoda belong to
The heritage dossier of the Department of Cultural Heritage records that the pagoda primarily follows the Lâm Tế (Linji) Zen school, introduced in the late 17th and early 18th centuries. Local accounts also connect the pagoda to the Trúc Lâm Zen stream of the Kinh Bắc region, and the Three Patriarchs of Trúc Lâm are worshipped inside. In July 2025, the pagoda was inscribed by UNESCO as a component site of the Yên Tử - Vĩnh Nghiêm - Côn Sơn, Kiếp Bạc World Heritage complex.
When was Bổ Đà Pagoda founded
Two chronological layers must be distinguished. The heritage dossier notes that according to oral tradition Quán Âm Pagoda on the mountain dates back to the Lý dynasty in the 11th century. However, all standing architecture today dates from the 18th-century Restored Lê period (restored under King Lê Dụ Tông in 1720 - 1729 by Founding Master Phạm Kim Hưng and expanded with Tứ Ân Pagoda under King Lê Cảnh Hưng by Zen Master Tính Ánh) with subsequent Nguyễn dynasty restorations.
What wood are the Bổ Đà woodblocks made of and when were they carved
The blocks are carved from persimmon wood (gỗ thị), a pale, fine-grained wood resistant to termites. Carving began under the Lê Cảnh Hưng reign (sources cite around 1740, 1741, or the earliest dated block in 1744) and continued into the early 20th century, featuring Chinese, Nôm, and Sanskrit scripts. The Department of Cultural Heritage dossier lists 1,935 blocks while press reports cite 1,953 or nearly 2,000 blocks, recognized as a National Treasure in 2017.
How many stupas are in the Bổ Đà Pagoda stupa garden
Sources vary slightly. The Department of Cultural Heritage dossier records 110 stupas and ancient tombs across nearly 8,000 square meters, VietnamPlus cites 107 stupas on 7,784 square meters, and other articles mention 97 or 102 ancient stupas. The number of monks and nuns whose relics rest here is recorded between 1,214 and over 1,218.
