Traveling from Đền Xưa (Xưa Temple) in Nghĩa Phú hamlet to Chùa Giám (Giám Pagoda), and from Chùa Giám on to Đền Bia (Bia Temple) in Văn Thai hamlet, the entire route covers only a few kilometers of country roads across rice fields. All three places have low roofs, wide courtyards and dense canopies of ancient trees, looking from the outside much like other village temples and pagodas of the northern Vietnamese delta. What sets them apart is that all three burn incense for the same person, and that person is neither a nature deity nor a king, but a physician.
That figure is Tuệ Tĩnh, born Nguyễn Bá Tĩnh, both a Zen monk and a renowned physician, born right in Nghĩa Phú village around the year 1330. The three sanctuaries divide his life into three clear roles, as Đền Xưa stands where he was born, Chùa Giám is where he practiced monastic life and dispensed medicine, and Đền Bia is linked to the stone stele bearing the parting message he sent home from a foreign land. One human life is held in trust by three plots of land, each keeping one chapter.
IThe honored figure and two overlapping layers of worship
Tuệ Tĩnh is a Buddhist Dharma name, not a birth name. According to widely cited records, his birth name was Nguyễn Bá Tĩnh, born around 1330 in Nghĩa Lư estate, now Nghĩa Phú hamlet, popularly called Xưa village, in the old Cẩm Giàng district. Orphaned of both parents at age six, he was raised and educated by monks at Hải Triều Pagoda and Giao Thủy Pagoda, taking the Dharma name Tiểu Huệ and then Huệ Tĩnh, later commonly read as Tuệ Tĩnh. At age twenty-two he passed the Thái học sinh doctoral examination under King Trần Dụ Tông but declined mandarin office, remaining in the monastic life and making the healing of poor villagers his life's work.
His guiding principle is summed up in a six-word maxim still repeated by practitioners of traditional medicine in Vietnam today, Southern medicine treats Southern people (Nam dược trị Nam nhân). That phrase was not a mere slogan, but a practical method, as he taught villagers to grow medicinal herbs right in their home gardens and use familiar local plants to treat common illnesses rather than relying on costly imported herbs. Two medical treatises associated with his name are Miraculous Efficacy of Southern Medicine (Nam dược thần hiệu) and Medical Compendium of Hồng Nghĩa (Hồng Nghĩa giác tư y thư).
It should be made clear that this complex holds two overlapping layers of worship, which visitors can observe as soon as they visit all three sites. The first layer is the veneration of a Zen master, because he was an ordained monk bearing a Dharma name, and Chùa Giám enshrines him in its Patriarchs' Hall (nhà tổ) in accordance with Buddhist monastic custom. The second layer is the veneration of a craft founder (tổ nghề), as traditional physicians and herbalists from across the country regard him as the founding master of their profession and come here to offer incense as disciples paying homage to a patriarch.
In traditional Vietnamese thought, those two layers do not conflict. The pagoda venerates the monk as a patriarch, the villages venerate the public benefactor as a tutelary human spirit (nhân thần), and the medical profession venerates the pioneer as a craft founder. One historical figure can receive all three forms of worship simultaneously, and Tuệ Tĩnh is one of the clearest examples of this convergence among heritage sites in northern Vietnam.
The final chapter of his life is recorded differently across sources. Most accounts state that in 1385, when he was fifty-five years old, the royal court sent him to Ming China, where he cured the Ming Empress of an illness, was granted the title Great Physician Zen Master (Đại y thiền sư) by the Ming Emperor and served at the Imperial Academy of Medicine before passing away in the Yangtze River region of Jiangnan, unable to return home. Some sources record that he was sent as tribute (bị cống), while others state that he was appointed as an envoy (đi sứ). The library records both accounts without choosing one arbitrarily, because those two expressions lead to very different readings of his final years.
What all sources agree upon is the inscription carved on his tomb stele in that foreign land, asking that if anyone from his homeland should visit in later times, they remember to bring his remains back home. That parting plea gave rise to the third sanctuary in this complex.
Many visitors assume that all three sites are temples dedicated solely to the physician, and that Chùa Giám is merely another name for a shrine. That is not the case. Chùa Giám is a complete Buddhist pagoda, bearing the Sino-Vietnamese name Nghiêm Quang Tự, with a Three Jewels hall, Buddha statues, a Patriarchs' Hall and regular monastic practice like any other Buddhist temple. Tuệ Tĩnh is venerated there as a monk who once resided and practiced medicine at the pagoda, rather than the pagoda having been built exclusively as his shrine. Understanding this distinction explains why a single heritage complex includes both a Buddhist pagoda and village temples, and why ceremonies at Chùa Giám follow Buddhist liturgy while festivals at Đền Bia and Đền Xưa follow village custom.
IIThree sanctuaries built in three eras
The three sites in the complex were neither built at the same time nor founded for the same immediate reason. Đền Xưa was raised at his birthplace according to the village custom of honoring a native son of great merit. Chùa Giám was already an ancient Buddhist pagoda where he practiced, predating his lifetime. Đền Bia arose last, born out of a diplomatic mission at the end of the 17th century.
- Around 1330Tuệ Tĩnh born in Nghĩa Phú villageNghĩa Lư estate, now Nghĩa Phú hamlet, popularly called Xưa village, in the old Cẩm Giàng district. This is where Đền Xưa was later erected.
- Lý eraFounding of Chùa GiámBearing the Sino-Vietnamese name Nghiêm Quang Tự and founded under the Lý dynasty beside the Thái Bình River, this pagoda was where Tuệ Tĩnh practiced Buddhism and treated patients in the 14th century.
- 17th centuryĐền Xưa established as a substantial templeBased on surviving architectural remains, heritage authorities have determined that by the 17th century a sturdy, finely carved temple stood on this site.
- 1677 to 1701First relocation of Chùa Giám and building of the Lotus HallIn 1677 the pagoda was moved away from eroding riverbanks. Two steles dated 1696 and 1701 record the large-scale rebuilding of the pagoda together with the Lotus Hall (nhà phẩm) housing the Nine-Tiered Lotus Tower.
- Around 1690The stele brought back to Văn ThaiDoctorate laureate Nguyễn Danh Nho (1638 to 1699), a native of the same Nghĩa Phú village, went on an embassy to Qing China, found Tuệ Tĩnh's tomb beside the Yangtze River and made a rubbing of the inscription to carve onto a new stone stele at home. When the boat carrying the stele capsized in the fields of Văn Thai hamlet, villagers raised the stele and built a shrine.
- 1846The Sacred Manifestation at Đền BiaOn the 1st day of the fourth lunar month in the sixth year of Thiệu Trị (1846), an event called the Sacred Manifestation (Thánh ứng) drew thousands of people to ask for medicine. A local mandarin had the stele confiscated to the Hải Dương provincial judge's residence and its characters chiseled off, before a storekeeper alerted Văn Thai villagers to bring the stele back to the temple.
- 1974 to 1975National ranking and relocation of Chùa GiámChùa Giám was ranked as a national heritage site in 1974 (followed by Đền Xưa in 1990 and Đền Bia in 1994). Between the seventh full moon of 1974 and the second full moon of the following year, the entire pagoda was dismantled and moved about seven kilometers to its present site to escape flooding.
- 2017Special national heritage siteThe Prime Minister signed Decision 2082/QĐ-TTg on December 25, 2017, ranking the Đền Xưa, Chùa Giám and Đền Bia complex as a special national heritage site.
The story of the stele at Đền Bia is closely tied to Doctorate laureate Nguyễn Danh Nho (1638 to 1699), a native of Nghĩa Phú village like Tuệ Tĩnh. While serving as an envoy to the north, he came upon the tomb of the Great Physician Zen Master beside the Yangtze River, and moved by the plea on the tomb stele, he took a rubbing of the inscription back to Vietnam and hired stonecutters to carve a new stele for his home village. According to local tradition, when the boat carrying the stele reached the flooded fields of Văn Thai hamlet, a storm sank the vessel, and the people of Văn Thai raised the stone and built a shrine around it. In 1846 local mandarins had the inscribed face chiseled away, yet the villagers preserved the stone stele inside the rear sanctuary. To honor the envoy who brought the message home, following the 2005 restoration a throne and ancestral tablet for Tiến sĩ Nguyễn Danh Nho were placed in the front hall of Đền Bia.
IIIThree sites, three architectural forms
Visiting all three sites reveals three distinct architectural layouts corresponding to three modes of worship. Written at the level of the complex, this section outlines the core structure of each sanctuary.
Located in Nghĩa Phú hamlet on the ground of his birthplace, built in a two-parallel-hall (chữ nhị) layout with a five-bay front hall and a three-bay rear sanctuary housing a wooden statue of Zen Master Tuệ Tĩnh. The temple preserves about fifty antiquities, including a bronze bell cast in 1855 and thirteen royal investiture edicts.
Sino-Vietnamese name Nghiêm Quang Tự, set on about two hectares in an inner-công outer-quốc layout comprising the triple gate, front hall, Three Jewels hall, Patriarchs' Hall and the Lotus Hall sheltering the Nine-Tiered Lotus Tower. The pagoda also preserves two great bronze bells cast in 1762 and 1848 along with sixteen stone steles from the 17th to 19th centuries.
Located in Văn Thai hamlet, first built in the Lê period, restored in 1936 in a front-nhất rear-đinh layout facing north, and comprehensively renovated in 2005 with over twenty structures. The rear sanctuary houses the stone stele and statue of Tuệ Tĩnh, the front hall enshrines the tablet of Tiến sĩ Nguyễn Danh Nho, and the grounds include a medicinal herb garden and traditional clinic.
Housed inside the Lotus Hall of Chùa Giám, nine tiers high and six-sided, each face about 1.2 meters wide, with eighteen statues per tier and 145 statues in all. Weighing roughly four tons, the wooden tower can be rotated by just a few people pushing it, and was recognized as a national treasure in 2015.
Regarding the height of the Nine-Tiered Lotus Tower, sources record different figures, which the library states directly rather than picking one arbitrarily. Some sources give a height of 4.44 meters. Others record 5.32 meters or 6 meters, noting that on the topmost tier sits a large statue of Amitabha Buddha about 1 meter tall whose head nearly touches the ceiling, or cite a total height of 6.52 meters including pedestal and finial. The discrepancy likely comes from measuring the timber shaft alone versus including the base and crowning statue, so readers should be aware of these different figures.
More important than the exact measurement is how the tower functions. The Nine-Tiered Lotus Tower is a nine-story wooden column mounted on a vertical axle so that it turns smoothly around its center. Worshippers chant the Buddha's name while pushing the tower to revolve, each full turn counting as one round of recitation. This kinetic form of devotion belongs to northern Vietnamese Pure Land and Zen practice, and because very few rotatable nine-tiered lotus towers survive in Vietnam today, the intact Late Lê example at Chùa Giám is a national treasure.
IVThe lie of the land and orientation
This section presents the library's reading through the lens of traditional feng shui, not content copied from stele inscriptions or the heritage dossier. The library notes this clearly so that readers can distinguish between historical documentation and interpretive reading.
All three sites lie on the alluvial delta of eastern northern Vietnam, flat and mountainless, crisscrossed by rivers, canals and ditches. In traditional site reading, such terrain has no mountain ranges to lean upon, so watercourses take the place of mountain veins, with flowing streams guiding qi and ponds gathering qi. That is why nearly every temple and pagoda in this delta region has a pond dug in front of its gate.
What is distinctive about this complex lies not in any single point, but in the relationship among the three points. The three sanctuaries neither line up along a single axis nor form a closed ring, but lie spread across a few kilometers of rice fields, each corresponding to a stage of life, namely birthplace, place of practice and place of homeward summons. Read in traditional terms, this is a tripartite distribution (thế phân tam), where qi is not compressed into a single node (huyệt) but spread across a landscape. Such a three-part pattern of veneration often arises around a figure who traveled far away and never returned in the flesh, leaving later generations to hold his memory across the home district.
Đền Bia in particular offers a striking geomantic story. The temple sits neither on a high mound nor inside an old residential hamlet, but right where the sunken stone stele came to rest in the middle of the fields. In traditional geomancy, finding a node usually means searching the terrain, whereas here the node revealed itself through the halting of a sacred object, and villagers simply built upon that spot. Taking the resting place of a relic as the site of a sanctuary reflects the old belief that the land itself claims its master rather than human beings forcing a site upon the land.
Chùa Giám represents the exact opposite case. Twice moved away from its old foundations to escape riverbank erosion and flooding, in 1974 the entire pagoda was dismantled and re-erected some seven kilometers from its former site. In traditional thought, once a building leaves its original ground, the old earth force no longer applies, and the anchor of the sanctuary shifts from the land to the sacred objects themselves, namely the ancient timber frame, the statues and the Nine-Tiered Lotus Tower carried along with it. While most northern Vietnamese monuments remain tied to their original foundations, here continuity resides in the timber structure and ritual treasures rather than the soil.
Regarding orientation, whereas temples and pagodas in the northern delta generally favor facing south or southeast, Đền Bia turns its front facade northward, looking back toward Nghĩa Phú village as if maintaining a line of sight and devotion toward the Zen Master's birthplace. Across these three sanctuaries honoring a patron of medicine, another telling detail is the placement of the medicinal herb garden. At Đền Bia, the garden of Southern medicinal plants grows right inside the temple compound, putting the sanctuary and the healing craft on the very same ground. In traditional terms, that is rightful placement (đắc vị), where form and purpose occupy their proper place.
VThe fourth lunar month festival and custom of asking for herbs
The largest festival of the complex falls at the beginning of the fourth lunar month, opening at Đền Bia with a procession to Đền Xưa, while Chùa Giám holds its own traditional festival in the middle of the second lunar month. Early fourth lunar month is when traditional medicine practitioners from many provinces gather to offer incense, giving the festival the character of a professional pilgrimage alongside a village celebration.
| Lunar date | Location | Details |
|---|---|---|
| 1st to 4th of the 4th month | Đền Bia | The main festival day is the 1st (commemorating the Sacred Manifestation). Includes announcement rites, ceremonial sacrifices, a foot procession between the two temples, commemorative incense offerings and the custom of asking for medicinal herbs. |
| Early 4th month and 15th of the 2nd month | Đền Xưa | Commemorative rites at the birthplace linked to the Đền Bia festival procession in the fourth month, along with the observance of the Zen Master's death anniversary on the full moon of the second lunar month. |
| 14th to 16th of the 2nd month and 15th of the 7th month | Chùa Giám | The traditional Chùa Giám festival runs from the 14th to the 16th of the second lunar month, alongside Ullambana (Vu Lan) and new- and full-moon Buddhist observances. |
| Early spring | All three sites | New Year pilgrims commonly visit all three sanctuaries in a single trip to pray for health. |
The most distinctive custom here is asking for medicinal herbs (lệ xin thuốc). Pilgrims place a few familiar home-garden medicinal leaves on the altar, commonly bamboo leaves, mugwort, chrysanthemum or areca, offer their prayers and then receive them back to use at home. This custom differs from ordinary temple blessings in that what is requested is neither coin nor votive paper, but the very healing craft of the figure worshipped. Because the grounds of Đền Bia also house a garden of Southern medicinal plants and a traditional clinic dispensing herbal prescriptions, the ritual of asking for herbs connects directly to real herbal medicine.
One point about the custom of asking for herbs should be stated clearly. Placing leaves upon the altar at the temple is a gesture of faith and remembrance honoring the founder of Southern Vietnamese medicine, whereas the act of placing a leaf on an altar does not by itself turn that leaf into a cure for every illness. The very master honored here taught that medicine must match the illness, that one must understand the properties of each herb, and that local plants must be grown and prepared with knowledge. Keeping the commemorative custom while seeking proper medical diagnosis and treatment is the truest way to honor his legacy.

- Getting there
- Đền Xưa in Nghĩa Phú hamlet and Đền Bia in Văn Thai hamlet both belong to Tuệ Tĩnh commune, while Chùa Giám belongs to Cẩm Giang commune, all within Hải Phòng city and separated by only a few kilometers of country roads. Visiting all three sites in a single trip is the most convenient approach.
- Coordinates
- 20.9778, 106.2536
All three sanctuaries are active places of worship, so visitors should observe local etiquette by dressing modestly, removing hats when entering inner halls, walking quietly and speaking softly in rear sanctuaries and Buddha halls, and placing donations in merit boxes rather than on ritual objects. At Chùa Giám, the Nine-Tiered Lotus Tower is a national treasure, so visitors should ask the pagoda caretakers before touching or pushing the tower. At Đền Bia, visitors wishing to take part in the custom of asking for medicinal herbs should ask the temple attendants about the proper local manner of presenting and receiving the leaves.

?Quick Questions
Who is worshipped at the Đền Xưa, Chùa Giám and Đền Bia Complex
All three sites honor Tuệ Tĩnh, born Nguyễn Bá Tĩnh around 1330, a Zen master and renowned physician who laid the foundations of Southern Vietnamese herbal medicine under the principle that Southern medicine treats Southern people. Đền Xưa honors him at his birthplace, Chùa Giám at the pagoda where he practiced, and Đền Bia around the stone stele bearing his parting message home.
Why does one person have three places of worship
Because the three sanctuaries preserve three chapters of his life. Đền Xưa marks his birthplace, Chùa Giám preserves the monastery where he practiced Buddhism and treated patients, and Đền Bia houses the stele brought back from the north by envoy Nguyễn Danh Nho after the Zen Master passed away in China. Located a few kilometers apart, all three are united in a single special national heritage dossier.
What is special about the Nine-Tiered Lotus Tower at Chùa Giám
Built at the end of the 17th century, it is a nine-tiered, six-sided wooden tower mounted on a vertical axle so that it can rotate, holding 145 statues and weighing about four tons. Worshippers chant while pushing the tower to turn. Recognized as a national treasure in 2015, its recorded height varies across sources from 4.44 meters and 5.32 meters to 6.52 meters.
When do the Đền Bia and Chùa Giám festivals take place
The main festival at Đền Bia runs from the 1st to the 4th day of the fourth lunar month, with the principal rites on the 1st, featuring ceremonial sacrifices, a foot procession between Đền Bia and Đền Xưa, and the custom of asking for herbs. The traditional festival at Chùa Giám takes place from the 14th to the 16th day of the second lunar month.
What is the custom of asking for medicine at Đền Bia
Pilgrims place familiar medicinal leaves such as bamboo, mugwort, chrysanthemum or areca on the altar, pray and receive them back for use, while the temple grounds also maintain a Southern herb garden and traditional clinic. Local records trace this custom to the 1st day of the fourth lunar month in 1846, remembered locally as the year of the Sacred Manifestation.
