Following the gentle course of the Nhuệ River through the scholarly heartland of Thượng Phúc south of old Thăng Long (now in Gia Phúc hamlet, Thượng Phúc commune, former Thường Tín district), visitors come upon a stately monastic complex shaded by ancient frangipani trees and crowned by a two-story, eight-roofed bell tower with soaring curved eaves. Passing through the Three-Entrance Gate and across a broad brick courtyard facing a crescent pond, a pair of vigorous Trần-dynasty stone dragons flanking the Front Hall steps and rows of ironwood pillars supporting moss-grown tile roofs carry pilgrims back to the atmosphere of an imperial National Temple once frequented by kings and princes.
This is Đậu Pagoda (Chùa Đậu), formally known as Thành Đạo Tự or Pháp Vũ Tự, the historic seat of Dharma Rain (Đức Pháp Vũ, or Lady Đậu) within Vietnam's ancient Four Dharma Goddesses (Tứ Pháp) pantheon. Beyond preserving Trần-dynasty stone dragons, Mạc-dynasty glazed floral bricks, and records of bronze plates inscribed with the legend of Mother Man Nương, Đậu Pagoda has astonished researchers worldwide with its two National Treasure whole-body relics (mummified statues) of seventeenth-century Zen Masters Vũ Khắc Minh and Vũ Khắc Trường, who have remained seated in meditation for nearly four hundred years.
IThành Đạo Tự, the cult of Dharma Rain (Lady Đậu), and the two self-mummified patriarchs of the Vũ clan
In the history of Vietnamese Buddhism (Buddhism), Đậu Pagoda bears several titles reflecting successive layers of sacred heritage. Its formal Sino-Vietnamese name inscribed on horizontal plaques and Restored Lê stelae is Thành Đạo Tự (成道寺, Temple of Attaining the Way), while its title derived from the principal deity enshrined in the Upper Hall is Pháp Vũ Tự (法雨寺, Temple of Dharma Rain). During the seventeenth-century reign of Emperor Lê Thần Tông and Lord Thanh Đô Vương Trịnh Tráng, because the royal court and lordly palace directly sponsored its grand reconstruction, the monastery was also honored as Quốc Tự (National Temple) and Đệ nhất danh lam (Foremost Scenic Sanctuary). Meanwhile, the vernacular name Đậu Pagoda (Chùa Đậu, or Bà Đậu) reflects both the old Nôm place name of the Gia Phúc area and the aspirations of farmers praying for timely rain and Confucian scholars praying to pass imperial examinations (đậu đạt).
The earliest spiritual stratum at Đậu Pagoda is the worship of Đức Pháp Vũ (the Goddess of Rain), the second deity of the Four Dharma Goddesses (Tứ Pháp): Pháp Vân (Cloud), Pháp Vũ (Rain), Pháp Lôi (Thunder), and Pháp Điện (Lightning), born in the early centuries CE from the synthesis of Indian Buddhism at Luy Lâu with indigenous Vietnamese agricultural spirit worship.
According to the ancient Sino-Nôm text Cổ Châu Pháp Vân Phật bản hạnh ngữ lục and regional lore of Luy Lâu and Thượng Phúc, during the second to third centuries CE (around the time of Governor Sĩ Nhiếp in Giao Châu), the Indian monk Khâu Đà La (Ksudra) taught at Linh Quang Pagoda in Luy Lâu (Bắc Ninh) and spiritually awakened a native maiden named Man Nương (Buddha Mother Man Nương). When a sacred ancient mulberry tree washed ashore at Luy Lâu, its trunk was carved into four wooden statues of the Four Dharma Buddhas to help farmers pray for rain: Pháp Vân (enshrined at Dâu Pagoda), Pháp Vũ (Dharma Rain), Pháp Lôi, and Pháp Điện. The wooden statue of Pháp Vũ was carried in procession to Gia Phúc beside the Nhuệ River, giving rise to Pháp Vũ Tự (Đậu Pagoda).
Historical chronicles and temple inscriptions record that across the Lý, Trần, and Lê dynasties, whenever severe drought struck the realm or great state ceremonies were held, the court dispatched high ministers or the monarch himself to escort the palanquin of Pháp Vũ from Đậu Pagoda to the capital Thăng Long for rain-invocation rites. Tradition further records that under Emperor Lý Thánh Tông and later under Emperor Lê Thần Tông, inscribed bronze plates (bronze books) recording the origin legend of the Four Dharma Goddesses and imperial charters were bestowed upon Pháp Vũ Tự (the text Cổ Châu Pháp Vân Phật bản hạnh ngữ lục was also later carved onto woodblocks in the 13th year of Cảnh Hưng, 1752, at Dâu Pagoda).
If Pháp Vũ embodies the early fusion of Buddhism and agricultural rain worship, in the seventeenth century Đậu Pagoda became the setting for an extraordinary attainment of Vietnamese Zen cultivation through Zen Master Vũ Khắc Minh (Dharma name Đạo Chân) and Zen Master Vũ Khắc Trường (Dharma name Đạo Tâm). According to Gia Phúc tradition and the official National Treasure dossier, the two masters were uncle and nephew born in Gia Phúc hamlet who succeeded one another as abbots of Đậu Pagoda during the Restored Lê dynasty (around the Dương Hòa era, 1635 - 1643). Around 1638 - 1639, Zen Master Vũ Khắc Minh entered a small hermitage cell behind the pagoda to undertake a hundred-day solitary retreat with only a jar of water and a jar of lamp oil. He instructed his disciples that once the sound of his wooden fish and chanting ceased completely, they should wait a full hundred days before opening the door: if his body had decayed, they should seal the cell with earth, but if it remained intact, they should coat it with natural lacquer and oil to preserve it as a relic. When the door was opened, his body remained seated upright in full lotus posture, remarkably light and untouched by decay. His nephew and successor, Zen Master Vũ Khắc Trường, later passed away and left behind an incorrupt whole-body relic through the very same ascetic practice.
Many people hearing of the mummified statues of Masters Vũ Khắc Minh and Vũ Khắc Trường assume they were preserved through chemical embalming similar to ancient Egyptian mummies (which required surgical removal of internal organs and chemical immersion). Repeated X-ray examinations and anthropological studies conducted by Vietnamese scientists (led by Assoc. Prof. Dr. Nguyễn Lân Cường and the Vietnam National Museum of History in 1983, 1999, and 2016) have proven the exact opposite: inside both statues lies a complete, naturally articulated human skeleton with no perforation of the skull and no surgical incision to remove organs. This is the East Asian Buddhist practice of self-mummification or whole-body relic preservation (tượng táng / nhục thân xá lợi): prior to passing, the master practiced strict dietary purification (subsisting on light herbs and roots before tapering down to pure water alone) combined with deep meditative breath control to deplete body fat and moisture, and after his passing, disciples sealed the exterior with aromatic sandalwood powder, refined clay, gauze cloth, and multiple coats of natural lacquer (sơn ta) to exclude air and moisture.
IINearly two millennia from the Sĩ Nhiếp era to the Lê - Trịnh National Temple and National Treasure status
From an early sanctuary honoring the Rain Goddess Pháp Vũ in the first centuries CE, Đậu Pagoda underwent major expansions under the Lý, Trần, and Mạc dynasties before reaching its grandest architectural form as an imperial National Temple in the seventeenth century under Emperor Lê Thần Tông and Lord Trịnh Tráng.
Cross-checking the antique stone stelae preserved at the pagoda (notably the stele erected in the fifth year of the Dương Hòa era, 1639, under Emperor Lê Thần Tông with an inscription composed by Doctorate scholar Bùi Bỉnh Quân, alongside the Mạc-dynasty stele of the sixth year of Sùng Khang, 1571), the library documents the royal restorations and notes a minor variation in the recorded name of the palace consort who served as chief patron. Under the Mạc dynasty (16th century), Empress Dowagers and royal princes donated generously to restore the pagoda, leaving behind its celebrated Mạc-dynasty glazed floral bricks. In the Restored Lê period, in the seventh year of the Đức Long era (1635), Emperor Lê Thần Tông, Lord Thanh Đô Vương Trịnh Tráng, and a favored palace consort (recorded in some stele translations as Consort Ngô Thị Ngọc Nguyên and in other sources as Ngô Thị Ngọc Loan, who gave birth to an heir after praying at the pagoda) sponsored a massive reconstruction encompassing over a hundred bays, bestowing the titles Đệ nhất danh lam (Foremost Scenic Sanctuary) and Quốc Tự (National Temple).
In modern heritage law, Đậu Pagoda was ranked a Grade-A National Historical and Artistic Heritage Site by the Ministry of Culture in 1964. On December 22, 2016, the Prime Minister signed Decision No. 2496/QĐ-TTg recognizing the Statues of Zen Master Vũ Khắc Minh and Zen Master Vũ Khắc Trường at Đậu Pagoda as a National Treasure (fifth batch). Regarding the monument's ranking level, while Hanoi authorities included Đậu Pagoda on a 2016 tentative list proposed for Special National Heritage consideration, its official statutory designation remains a National Historical and Cultural Heritage Site housing a National Treasure. Administratively, under Resolution No. 1656/NQ-UBTVQH15 dated June 16, 2025 of the Standing Committee of the National Assembly, former Nguyễn Trãi commune merged with Tân Minh, Dũng Tiến, Quất Động, and Nghiêm Xuyên communes of former Thường Tín district to establish the new Thượng Phúc commune of Hanoi (reviving the historic prefecture name of Thượng Phúc).

IIIInner-Công outer-Quốc royal architecture, the Pháp Vũ statue, and the National Treasure mummified masters
The architectural complex of Đậu Pagoda follows the classic inner-Công, outer-Quốc (內工外國) layout characteristic of seventeenth-century royal monasteries. Entering from the outside, visitors pass beneath the Three-Entrance Gate and Bell Tower (Tam quan - Gác chuông), a two-story, eight-roofed ironwood structure whose soaring corner eaves curve like phoenix wings. Its upper loft houses a bronze bell cast in the ninth year of Cảnh Thịnh (1801) alongside a gilded wooden gong. Across the wide brick courtyard stands the central Công-shaped sanctuary comprising the Front Hall (Tiền đường), Incense Hall (Thiêu hương), and Upper Hall (Thượng điện), flanked by two long side corridors leading back to the Rear Hall and the two brick Relic Stupa Shrines (Nhà Tổ / Am Nhục Thân).
In the innermost chamber of the Upper Hall, framed by magnificent seventeenth-century gilded openwork doors carved with dragons and phoenixes, sits the nearly two-meter wooden statue of Đức Pháp Vũ (Lady Đậu). Sculpted as a noble yet compassionate Vietnamese woman seated upon a giant lotus throne, the statue is finished in a deep plum-brown lacquer characteristic of the Four Dharma icons, her serene eyes cast gently downward and her right hand raised in the gesture of teaching the Dharma and bestowing rain.
Scientific specifications of the National Treasure mummified statues and four-dynasty antiquities
Behind the main sanctuary stand two ancient brick stupa shrines housing the National Treasure Statues of Zen Master Vũ Khắc Minh and Zen Master Vũ Khắc Trường inside climate-controlled glass enclosures. According to the National Treasure dossier of the Department of Cultural Heritage (dsvh.gov.vn) and the 1999 scientific conservation report led by Assoc. Prof. Dr. Nguyễn Lân Cường: the mummified statue of Zen Master Vũ Khắc Minh measures 57 cm to 58.5 cm in seated height and weighs an astonishingly light 7 kg to 7.5 kg, his head inclines slightly forward, his left hand rests upon his right in the samadhi mudra, his nasal bridge remains prominent, his lips are gently closed, and real beard hairs still survive beneath his chin. The mummified statue of Zen Master Vũ Khắc Trường sits slightly taller (about 63 cm to 75 cm including its built-up base) and weighs about 11.5 kg to 12 kg after having been scientifically conserved with traditional natural lacquer following twentieth-century flood damage from the Nhuệ River.
Alongside these two peerless whole-body relics, Đậu Pagoda preserves stone and ceramic masterpieces spanning four dynasties: flanking the Front Hall steps is a pair of Trần-dynasty stone dragons over two meters long carved in the round with robust bodies, large scales, and flowing manes, and inside the halls are Mạc-dynasty glazed floral bricks molded in relief with dragons, phoenixes, and lotuses, together with dozens of stone stelae dating from 1571 to the nineteenth century.
Two 17th-century whole-body relics recognized as a National Treasure in 2016: Master Vũ Khắc Minh's statue stands about 58 cm tall and weighs just over 7 kg, Master Vũ Khắc Trường's stands about 63 - 75 cm tall, each enclosing a complete, unembalmed human skeleton in lotus posture.
A nearly 2 m wooden statue finished in deep plum-brown lacquer atop a lotus throne inside the Upper Hall, representing the Goddess of Rain in Vietnam's ancient Four Dharma system.
Two monolithic blue-stone stairway balustrades from the Trần dynasty (13th - 14th centuries) carved with undulating dragons holding pearls in their mouths, attesting to the Lý - Trần antiquity of Pháp Vũ Tự.
An ironwood Tam quan bell tower with two stories and eight sweeping roofs, complemented by openwork relief panels, dragon-head brackets, and ceremonial doors from the 1635 royal reconstruction.
A rare collection of Mạc-dynasty glazed terracotta bricks molded with lotuses and sacred animals, alongside major stone stelae erected in the 6th year of Sùng Khang (1571) and 5th year of Dương Hòa (1639).
IVThe lie of the land and orientation
This section presents the library's own field reading through the lens of traditional form-school feng shui in Gia Phúc hamlet beside the Nhuệ River, rather than statements copied from the pagoda's stelae. We state this clearly so that readers can distinguish historical records from geomantic interpretation.
Viewed within the hydrography and alluvial plain south of old Thăng Long at coordinates 20.85240°N, 105.85820°E, Đậu Pagoda occupies a high, tortoise-shell-shaped rise of land in Gia Phúc hamlet directly on the left (eastern) bank of the ancient Nhuệ River. In the feng shui of the Red River delta, where high mountain ranges are absent, watercourses (rivers and ponds) serve as the primary conductors of dragon veins and gatherers of qi: the Nhuệ River (Nhuệ Giang), drawing its water from the Red River, curves gently around Thượng Phúc like a jade-girdle waterway (ngọc đái thủy) embracing the monastery grounds. Moreover, because the principal deity of Đậu Pagoda is Đức Pháp Vũ (the Goddess of Rain, belonging to the Water element), siting the sanctuary right beside the Nhuệ River with a broad crescent pond in front of the Tam quan establishes a resonant communion of Water qi, making the pagoda the preeminent rain-prayer sanctuary of the dynastic era.
In terms of orientation and spatial hierarchy, the sacred axis of Đậu Pagoda (running from the Tam quan Bell Tower through the Front, Incense, and Upper Halls to the two Relic Stupas at the rear) sits in the North slightly toward the East and faces South slightly toward the West (sitting on Quý facing Đinh, or sitting on Sửu facing Mùi), looking directly out over the large front pond as the inner bright hall (nội minh đường) and the Nhuệ River beyond as the outer bright hall (ngoại minh đường). Facing South is the classical imperial orientation (the ruler faces south to govern the realm), befitting a National Temple (Quốc Tự) patronized by Emperor Lê Thần Tông and Lord Trịnh Tráng. Flanked by two long side corridors and ancient bamboo and frangipani groves forming the Azure Dragon on the left, White Tiger on the right, the elevated rear terrace behind the Upper Hall gathers the deepest, most tranquil yin-yang balance to shelter the incorrupt whole-body relics of Zen Masters Vũ Khắc Minh and Vũ Khắc Trường across four centuries.
VThe grand Đậu Pagoda festival and traditional water-procession and rain-prayer rites
The Đậu Pagoda festival is one of the largest Buddhist and agricultural festivals south of Hanoi, preserving the ancient palanquin processions of the Four Dharma Goddesses, memories of royal progressions to the National Temple, and deep veneration for the two self-mummified patriarchs.
| Lunar date | Festival name | Key rituals and cultural activities |
|---|---|---|
| 8th to 10th day of the 1st lunar month | Grand Spring Festival of Đậu Pagoda | Palanquin processions from the villages of the Gia Phúc - Thượng Phúc area, water-fetching procession from the Nhuệ River, grand sacrifices to Đức Pháp Vũ (Lady Đậu), incense offerings at the stupas of the two Vũ Zen Masters, and dragon dances. |
| 8th day of the 4th lunar month | Buddha's Birthday and Four Dharma Rain-Prayer Festival | Traditional bathing of the Buddha statue and sutra recitations praying for timely rain and bountiful harvests according to the ancient Four Dharma calendar. |
| Autumn and death anniversaries of the two Vũ Patriarchs | Memorial rites for Zen Masters Vũ Khắc Minh and Vũ Khắc Trường | Monks and residents of Gia Phúc hamlet hold solemn patriarchal memorial services at the two brick relic stupas behind the Upper Hall. |
| Prior to major academic examinations | Scholarly prayers for examination success (Cầu Đậu) | A cherished custom in the scholarly land of Thượng Phúc - Thường Tín (homeland of Nguyễn Trãi and 68 Confucian doctorate laureates), where students visit Đậu Pagoda to pray for wisdom and academic success. |
Because the Thượng Phúc - Thường Tín region is famed both as a land of a hundred traditional crafts and a cradle of Confucian scholarship that produced 68 imperial doctorate laureates, alongside its ancient rain-prayer role for rice farmers, the word Đậu (meaning to pass an examination) in the pagoda's name has made it a beloved spiritual destination for generations of students before major exams.

?Quick Questions
Who is worshipped at Đậu Pagoda, and why was it honored as a National Temple (Quốc Tự)?
Đậu Pagoda (Thành Đạo Tự / Pháp Vũ Tự) primarily enshrines Đức Pháp Vũ (Lady Đậu, the Goddess of Rain in Vietnam's ancient Four Dharma pantheon) alongside the Three Jewels of Buddhism and the two patriarchs Vũ Khắc Minh and Vũ Khắc Trường. In 1635, under Emperor Lê Thần Tông and Lord Trịnh Tráng, the royal court sponsored a massive reconstruction and regularly held state rain-prayer rites here, elevating the pagoda to a National Temple and Foremost Scenic Sanctuary.
Whose mummified statues are preserved at Đậu Pagoda, and when were they named a National Treasure?
They are the whole-body relics (mummified statues) of two seventeenth-century abbots of Đậu Pagoda who were uncle and nephew: Zen Master Vũ Khắc Minh (Dharma name Đạo Chân, who passed away around 1638 - 1639) and Zen Master Vũ Khắc Trường (Dharma name Đạo Tâm). On December 22, 2016, the Prime Minister signed Decision No. 2496/QĐ-TTg recognizing both statues as a National Treasure.
How have the bodies of the two Zen Masters survived nearly 400 years without chemical embalming?
X-ray examinations by Vietnamese scientists confirm that each statue contains a complete, naturally articulated human skeleton with no skull perforation or surgical removal of internal organs. Both masters practiced solitary dietary tapering (gradually fasting down to water alone while meditating for 100 days in a sealed cell) to eliminate body fat and moisture, and after their passing, disciples sealed the exterior with aromatic wood powder, gauze cloth, and natural lacquer (sơn ta).
Besides the two mummified statues, what other rare antiquities are preserved at Đậu Pagoda?
Đậu Pagoda preserves the nearly two-meter wooden statue of Đức Pháp Vũ in the Upper Hall, a pair of monolithic Trần-dynasty stone dragons (13th - 14th centuries) flanking the Front Hall steps, a collection of Mạc-dynasty glazed floral terracotta bricks (16th century), major stone stelae from 1571 and 1639, and a two-story, eight-roofed ironwood Bell Tower.
Following the 2025 administrative reorganization, which commune of Hanoi does Đậu Pagoda belong to?
Prior to July 2025, Đậu Pagoda belonged to Gia Phúc hamlet, Nguyễn Trãi commune, Thường Tín district, Hanoi. Under Resolution No. 1656/NQ-UBTVQH15 dated June 16, 2025 of the Standing Committee of the National Assembly, Nguyễn Trãi commune merged with Tân Minh, Dũng Tiến, Quất Động, and Nghiêm Xuyên communes to form Thượng Phúc commune of Hanoi.
