Following the coastal road that winds along the foot of the Nine Dragons (Cửu Long) range on the Đồ Sơn peninsula to the slope of Mount Vạn Tác in Zone 1, Đồ Sơn ward (Hải Phòng city), visitors encounter a setting wholly unlike the timber pagodas of the northern plains. Directly ahead, the waves of the East Sea wash unceasingly against rocky crags, while immediately behind rises a rugged cliff face opening into a natural stone cavern penetrating deep into the mountain. This is Chùa Hang Pagoda in Đồ Sơn, known by its classical Sino-Vietnamese title Cốc Tự (谷寺, meaning the Temple in the Cave).
Remarkable not only for a worship space formed entirely within a natural grotto, Chùa Hang holds a foundational place in the religious and intellectual history of Vietnam. According to coastal oral traditions and numerous studies in Vietnamese Buddhist history, this very cavern on the shore of Nê Lê (the ancient name of the Đồ Sơn region) was where the monk Phật Quang (locally revered as Sư Bần) from Tianzhu (ancient India) arrived aboard a merchant vessel to establish a practice center and transmit the Buddha's teachings as early as the second century BCE, predating even the celebrated Luy Lâu Buddhist center in Kinh Bắc.
IThe Indian monk Phật Quang (Sư Bần), the Nê Lê Buddhist site, and the legend of Chử Đồng Tử learning the Way
Within the heritage of Vietnamese Buddhism, Chùa Hang Pagoda in Đồ Sơn bears the classical Chinese name Cốc Tự (谷寺) or Phật Quang Cốc Tự (佛光谷寺). In classical Chinese, the character Cốc (谷) denotes a narrow mountain valley or a natural rock cavern, faithfully reflecting the temple's primal form: rather than felling timber or firing bricks to erect a grand hall, early practitioners sheltered directly within a natural stone chamber at the foot of Mount Vạn Tác (also called Mount Tiên Sơn) to meditate, keep out the elements, and set up an altar to the Buddha.
The central figure venerated as the founding patriarch of Cốc Tự is Master Phật Quang, whom fishing communities across the Đồ Sơn peninsula have affectionately called Sư Bần (or Patriarch Bần) for generations. According to oral traditions around the Nam Triệu estuary and the Đồ Sơn peninsula, around the second century BCE (late Hùng Kings to early An Dương Vương period), he was an eminent monk from Tianzhu (India) who crossed the ocean aboard merchant ships trading spices and southern goods. When his vessel anchored off the coastal territory of Nê Lê (the ancient name encompassing Đồ Sơn and its vicinity), he saw a mountain promontory reaching into the sea with auspicious terrain and a secluded cavern facing the ocean. Remaining behind, he turned the cave into a meditation hermitage, dug a freshwater well right inside the rock, and taught the compassionate Dharma to local inhabitants.
The presence of the Cốc Tự practice center is bound up with a striking cultural encounter between early maritime Indian Buddhism and indigenous Vietnamese immortalist beliefs. According to the tale of Nhất Dạ Trạch (The One-Night Marsh) in the medieval collection Lĩnh Nam chích quái and Red River delta folklore, the poor youth Chử Đồng Tử and Princess Tiên Dung (daughter of the eighteenth Hùng King) sailed out to sea on a merchant voyage and stopped at a coastal island mountain (Quỳnh Viên / Nê Lê) to draw fresh water. In a stone hermitage on that mountain, the couple met the monk Phật Quang, stayed to hear his exposition of the sutras, and received instruction in spiritual cultivation before being bestowed a bamboo staff (trượng) and a palm-leaf hat (mao) through which they manifested miraculous powers. The image of an Indian monk seated in a coastal cave transmitting the Dharma to the foremost of Vietnam's Four Immortals illustrates how Buddhism entered Giao Châu not through conflict, but through gentle harmony with indigenous spiritual consciousness.
From the perspective of Buddhist historiography and archaeology, the account of Master Phật Quang at Chùa Hang Pagoda opens a vital scholarly inquiry into the maritime introduction of Buddhism to Vietnam. In foundational histories of Vietnamese Buddhism by scholars such as Nguyễn Lang (Zen Master Thích Nhất Hạnh), Lê Mạnh Thát, and researchers at the Vietnam Buddhist Research Institute, the territory of Nê Lê (Đồ Sơn, Hải Phòng) is identified as the first maritime gateway welcoming Indian merchants and monks sailing from the Indian Ocean through the Strait of Malacca into the Gulf of Tonkin. Because the Đồ Sơn peninsula juts out into the sea like a natural beacon, ancient merchant vessels sailing north used Mount Đồ Sơn as a navigational landmark, storm shelter, and freshwater station before following the Bạch Đằng, Cấm, Thái Bình, and Dâu rivers inland toward the capital center of Luy Lâu (Thuận Thành, Bắc Ninh).
Consequently, many historians conclude that the Nê Lê Buddhist site at Chùa Hang in Đồ Sơn served as the coastal vanguard of Indian Buddhism in Giao Châu from the second century BCE to the turn of the Common Era, laying the direct foundation for the flourishing Luy Lâu Buddhist center of the first and second centuries CE (home to Dâu Pagoda dedicated to Pháp Vân), from which Buddhism subsequently spread northward to Pengcheng and Luoyang in China.
A common point of confusion for visitors listening to popular accounts is the conflation of Patriarch Phật Quang (Sư Bần) with the First Zen Patriarch Bodhidharma (Bồ Đề Đạt Ma). In reality, because both Sư Bần and Bodhidharma were Indian monks who crossed the sea to transmit the Dharma in the East and both are associated with cave meditation (Bodhidharma meditated facing a wall for nine years in a cave on Mount Shaoshi in the sixth century CE, whereas Sư Bần meditated in the Đồ Sơn cave in the second century BCE according to local tradition), the expanded grounds of Chùa Hang today feature both a monolithic blue-stone statue of Patriarch Bodhidharma outdoors and the ancient blue-stone statue of Patriarch Bần (Phật Quang) deep inside the cave. Visitors should distinguish clearly between the eras and biographies of these two masters when paying homage.
IIMore than two millennia from the Nê Lê stone hermitage to a cultural heritage site of Hải Phòng
Across more than two thousand years of coastal winds and storms, Chùa Hang Pagoda in Đồ Sơn embodies both the legendary dawn of Vietnamese nation-building and the historical milestones of the Hải Phòng seacoast through the Lý, Trần, Lê, and Nguyễn dynasties down to the present day.
When cross-referencing historical sources on Chùa Hang Pagoda and the ancient toponym Nê Lê, the library notes two scholarly distinctions so readers may grasp the full documentary picture. First, regarding the founding date and the location of Nê Lê citadel: according to Đồ Sơn oral tradition and studies published in the Journal of Buddhist Studies, the monk Phật Quang (Sư Bần) established his hermitage in the Đồ Sơn cave in the second century BCE, and the Đồ Sơn peninsula (together with Tường Long Stupa atop Mount Ngọc) is directly linked to the ancient name Nê Lê. Meanwhile, classical Chinese geographical texts (such as the Shuijing zhu quoting the Jiaozhou waiyu ji) and the Đại Việt sử ký toàn thư mentioning Nê Lê citadel or Nê Lê pagoda during the Northern Domination and Lý periods (including Emperor Lý Thánh Tông erecting a stupa at Đồ Sơn in 1058) have prompted modern archaeologists to debate the broader territorial extent of Nê Lê stretching from the Đồ Sơn peninsula inland toward Thủy Nguyên and An Dương. Regardless of the exact administrative boundaries of ancient Nê Lê, scholars agree that the Đồ Sơn peninsula and Chùa Hang remain the most prominent coastal monument preserving tangible relics and living memories of this early Buddhist landing.
Second, regarding the spatial shift of the pagoda's architecture: prior to the twentieth century, all worship activities of Cốc Tự took place right inside and in front of the natural rock cavern at the foot of Mount Vạn Tác. In the mid-twentieth century, historical upheavals and natural weathering caused partial rockfalls at the cave mouth and damaged or buried several ancient stone objects (such as an old stone altar and an earlier stone Amitabha statue). Between the 1990s and 2000s, to preserve the original grotto intact while accommodating growing numbers of pilgrims, the temple and local community constructed a new three-story pagoda complex (housing the Three Jewels Hall and the Western Paradise Hall) on the hillside about 100 meters from the ancient cave entrance. On August 10, 2010, the People's Committee of Hải Phòng City issued Decision No. 1347/QĐ-UBND ranking Chùa Hang (Cốc Tự) as a Municipal (Provincial-level) Historical and Cultural Heritage Site.
- 2nd century BCEMonk Phật Quang (Sư Bần) opens a practice center in the Nê Lê caveAccording to tradition and Buddhist historical studies, an Indian monk named Sư Bần (honored as Phật Quang) arrived by merchant ship on the Nê Lê coast (Đồ Sơn), choosing a natural cavern at the foot of Mount Vạn Tác to meditate, teach local fisherfolk, and instruct Chử Đồng Tử and Tiên Dung.
- 11th - 14th centuryFlourishing alongside the Đồ Sơn Buddhist center under the Lý and Trần dynastiesDuring the Lý and Trần eras, when the royal court erected Tường Long Stupa (in 1058 under Emperor Lý Thánh Tông) and Vân Bản Pagoda on Mount Đồ Sơn, Cốc Tự at the foot of Mount Vạn Tác remained a sacred pilgrimage site for inhabitants of Vạn Tác in Nghi Dương district.
- 17th - 19th centuryPreservation of cave worship under the Lê and Nguyễn dynastiesResidents of Vạn Tác (formerly Đồ Sơn commune, Nghi Dương district, Kinh Môn prefecture, Hải Dương province) maintained incense offerings at Cốc Tự, safeguarding the blue-stone statue of Patriarch Bần, the stone incense burner, and the freshwater well inside the cave.
- Mid-20th centuryHistorical upheavals damage part of the outer cave mouthAround the middle of the twentieth century, historical disturbances caused partial collapse of the outer rock overhang and loss of several old stone artifacts, though local residents protected the blue-stone statue of Sư Bần and the inner cave altar.
- 1990s - 2000sConstruction of the new three-story pagoda complex beside the ancient caveTo protect the original rock cavern and expand space for Buddhist practice, a new three-story temple building (comprising a support ground floor, the Three Jewels Hall, and the Western Paradise Hall) was built about 100 meters from the ancient cave.
- 2010Designation as a Municipal Historical and Cultural Heritage SiteOn August 10, 2010, the People's Committee of Hải Phòng City issued Decision No. 1347/QĐ-UBND recognizing Chùa Hang (Cốc Tự) as a city-level historical and cultural heritage site.
- 2020 - 2025Administrative reorganization into the new Đồ Sơn wardIn 2020, Vạn Sơn ward merged with Ngọc Hải ward to form Hải Sơn ward under Resolution No. 872/NQ-UBTVQH14. Effective July 1, 2025, under Resolution No. 1669/NQ-UBTVQH15, Hải Sơn ward merged with neighboring wards to form the new Đồ Sơn ward of Hải Phòng city.
IIISurvey of the 25-meter natural grotto, the blue-stone statue of Patriarch Bần, and the three-story sanctuary
The overall space of Chùa Hang Pagoda (Cốc Tự) today harmonizes two distinct zones: the original ancient rock cavern (the temple inside the cave) nestled beneath the cliff of Mount Vạn Tác and the new pagoda complex built on the adjacent hillside about one hundred meters from the old cave mouth. Stepping into the ancient cave zone, visitors immediately feel the cool air radiating from the coastal sedimentary rock. According to field measurements by Hải Phòng heritage authorities, the natural cavern has a trapezoidal cross-section penetrating approximately 25 meters into the mountain. Its seaward-facing mouth measures about 3.5 meters high and 7 meters wide.
The cave floor is divided into two natural stone terraces: an outer terrace of about 23 square meters where pilgrims stand to pay homage, and an inner terrace raised about 0.5 meters higher where the ancient altar stands. The deeper one goes into the mountain, the narrower and lower the rock vault becomes along the geological fissure: at the innermost recess at the back of the cave, the ceiling height drops to about 1.2 meters and the width narrows to about 1.3 meters, naturally compelling every pilgrim to bow low in reverence. Right within this hushed subterranean chamber rests the ancient monolithic blue-stone statue of Patriarch Bần (Phật Quang) alongside an antique stone incense burner and a freshwater well that never runs dry.
A trapezoidal natural grotto penetrating the coastal cliff of Đồ Sơn, with a mouth 3.5 m high and 7 m wide, divided inside into two stone terraces (outer terrace 23 sq.m, inner terrace 0.5 m higher) and narrowing at the rear to 1.2 m high by 1.3 m wide.
The temple's most precious sculptural relic placed on the stone altar inside the cave: carved from blue stone about 0.59 m to 0.60 m tall, depicting the Indian monk seated in auspicious meditation posture (right foot visible) on a lotus pedestal, with tightly curled hair knots, long earlobes, and a serene, compassionate countenance.
Directly in front of the stone statue of Sư Bần stands an antique blue-stone incense burner shaped like a three-legged cauldron. Beside the cave entrance and within the rock lies an ancient freshwater well that remains crystal-clear year-round despite being steps from the salty sea, traditionally used by Patriarch Phật Quang.
In the shaded hillside grounds stands a solemn statue of the First Zen Patriarch Bodhidharma carved from a single block of blue stone, accompanied by open-air shrines and patriarch stupas.
Located about 100 m from the ancient cave, the three-story hillside building houses a ground-floor dining and support area, a second-floor Three Jewels Hall venerating Shakyamuni Buddha and Bodhisattvas, and a third-floor Western Paradise Hall dedicated to Amitabha Buddha together with Mother Goddess and Saint Trần altars in the 'Buddha in front, Deities behind' arrangement.
Archaeologists and art historians examining the blue-stone statue of Patriarch Bần (0.59 - 0.60 meters tall) at Chùa Hang in Đồ Sơn have noted its distinctive iconographic features. Unlike Lê- and Nguyễn-dynasty portrait statues of Vietnamese patriarchs, which typically wear multi-layered monastic robes and sit in full lotus posture with both feet concealed, the stone statue at Cốc Tự depicts the monk seated on a lotus throne in the auspicious half-lotus posture with the sole of his right foot upturned, his head bare with small spiral curls, long thick earlobes, and a prominent nasal bridge evoking the physical traits of an Indian ascetic. Even though the surviving stone carving itself was crafted in later dynastic centuries to honor the founding master, these iconographic details faithfully preserve the historical memory of Master Phật Quang from Tianzhu.
IVThe lie of the land and orientation
This section presents the library's reading through the eyes of traditional landform feng shui based on the actual topography of the Đồ Sơn peninsula and the Nine Dragons mountain range, rather than content copied from monument inscriptions. The library states this clearly so readers may distinguish historical records from geomantic interpretation.
Examined on the topographic map at approximately 20.7202 degrees north latitude and 106.7805 degrees east longitude, Chùa Hang Pagoda (Cốc Tự) commands one of the most dramatic mountain-and-sea geomantic formations along the northern Vietnamese coast. The Đồ Sơn peninsula is a spur of earth and sandstone hills extending from the mainland into the sea along a northwest-southeast axis, consisting of nine consecutive peaks undulating like a great dragon swimming out into the ocean, whence its ancient name Cửu Long sơn (Nine Dragons Mountain). Chùa Hang forms the node (huyệt) right on the northeastern flank at the foot of the very first peak of the Nine Dragons range, Mount Vạn Tác (also called Mount Tiên Sơn, the mother peak of the peninsula). In classical landform reading, the rock cavern sits precisely at the stone bone and mountain root where the cliff meets the sea, embodying the posture of backed by mountain, facing the sea (its back resting against the solid cliff of Mount Vạn Tác, its mouth looking straight out across the East Sea).
Looking outward from inside the cavern toward the east and northeast, the vast expanse of Đồ Sơn Bay and the Nam Triệu estuary opens infinitely as a grand water-gathering bright hall (minh đường). Here, the subtlety of nature manifests through the mutual complement of yin and yang within the living rock: just a few dozen paces in front of the pagoda roll the salty waves of the ocean (outer water bright hall), yet right inside the rock cavern and at the foot of Mount Vạn Tác wells up an ancient freshwater spring that stays cool and sweet year-round, never drying up and never turning brackish. In landform feng shui, a pure freshwater spring rising out of coastal rock right beside the salt sea is called a spring hidden in stone (thạch trung ẩn tuyền), signifying where the vital qi of the Nine Dragons dragon vein (long mạch) condenses into true water to nourish spiritual practitioners. On either side, rocky spurs of Mount Vạn Tác curve around the coastal crags as a protective Azure Dragon on the left, White Tiger on the right, shielding the cave mouth from direct gale winds and preserving Cốc Tự as an enduring Dharma sanctuary for over two millennia.
VThe Chùa Hang spring festival and pilgrimage customs at the Nê Lê Buddhist cradle
For coastal communities in Đồ Sơn and pilgrims across Hải Phòng city, Chùa Hang Pagoda (Cốc Tự) is a sacred ancestral sanctuary where people pray for safety before each fishing season and at the start of every lunar new year. Annual observances at the pagoda preserve Northern Buddhist liturgy while reflecting the vibrant maritime culture of the coast.
| Lunar date | Festival and event | Ritual content and activities |
|---|---|---|
| 1st to 6th day of the 1st lunar month | Chùa Hang Đồ Sơn Spring Festival | The main annual festival of the heritage site. Residents of Đồ Sơn and pilgrims from afar gather to offer incense at the Three Jewels Hall and enter deep into the ancient rock cavern to bow before Patriarch Bần (Phật Quang), praying for national peace, favorable weather, and bountiful catches at sea. |
| 15th day of the 1st lunar month | First Full Moon Peace Prayer (Lễ Thượng nguyên) | The temple conducts Medicine Buddha sutra chanting and New Year peace prayers for all families. Pilgrims often request a small portion of freshwater from the Patriarch's ancient well for health and serenity. |
| 15th day of the 4th lunar month | Buddha's Birthday Celebration (Đại lễ Phật Đản) | Commemorating the birth of Shakyamuni Buddha. At this ancient Nê Lê Buddhist cradle, the bathing-of-the-Buddha ceremony and dharma talks recounting Master Phật Quang's arrival in Giao Châu are solemnly held. |
| 15th day of the 7th lunar month | Vu Lan Filial Piety Festival and Requiem Rites | Honoring the grace of parents while holding requiem prayers for fallen heroes and fishermen or sailors who perished at sea. |
| 1st and 15th days of every lunar month | Twice-monthly new and full moon observances | Elderly laywomen and Buddhists of Đồ Sơn ward gather to chant sutras in the Three Jewels Hall and Western Paradise Hall and offer incense to the founding patriarch inside the rock cave. |
Whenever the tolling of the temple bell mingles with the sound of waves breaking at the foot of Mount Vạn Tác, pilgrims stepping into the dim rock cavern feel transported back to the earliest wellspring of Vietnamese Buddhism. From a humble stone hermitage tended by an Indian monk on the coast of Nê Lê more than two thousand years ago, the lamp of the Dharma spread across the Red River delta to forge a Buddhist tradition that has accompanied the nation throughout its history.

?Quick Questions
Why is Chùa Hang Pagoda in Đồ Sơn called Cốc Tự and regarded as the earliest site where Buddhism entered Vietnam?
The classical name Cốc Tự means a Buddhist temple situated inside a natural rock cave. According to oral tradition and Buddhist historical studies, in the second century BCE an Indian monk named Sư Bần (honored as Phật Quang) arrived by merchant ship on the coast of Nê Lê (Đồ Sơn) and chose the natural cavern at the foot of Mount Vạn Tác to establish the first Buddhist practice center in Giao Châu before the Dharma spread inland to Luy Lâu.
How is the monk Phật Quang (Sư Bần) at Chùa Hang connected to the legend of Chử Đồng Tử and Tiên Dung?
According to folk tradition and the tale of Nhất Dạ Trạch in the Lĩnh Nam chích quái, Chử Đồng Tử and Princess Tiên Dung sailed out to sea on a merchant trading voyage and stopped at a coastal mountain to draw fresh water. There they met the monk Phật Quang meditating in his stone hermitage, stayed to study the Dharma under him, and received a bamboo staff and palm-leaf hat endowed with miraculous powers.
What are the dimensions and features of the ancient rock cave and the statue of Patriarch Bần at Chùa Hang?
The natural rock cavern of Cốc Tự has a trapezoidal shape extending about 25 meters deep into the mountain, with an entrance about 3.5 meters high and 7 meters wide that narrows toward the rear to 1.2 meters high. Inside the cave rests an antique monolithic blue-stone statue of Patriarch Bần measuring about 0.59 to 0.60 meters tall, seated in auspicious meditation posture on a lotus pedestal with curled hair knots and long earlobes, fronted by an antique tripod stone incense burner.
When was Chùa Hang Pagoda ranked as a heritage site and which administrative unit does it belong to today?
Chùa Hang (Cốc Tự) was ranked as a Municipal (Provincial-level) Historical and Cultural Heritage Site by the People's Committee of Hải Phòng City under Decision No. 1347/QĐ-UBND on August 10, 2010. Administratively, the site belonged to Vạn Sơn ward prior to 2020, Hải Sơn ward from 2020, and since July 1, 2025 belongs to the new Đồ Sơn ward of Hải Phòng city under Resolution No. 1669/NQ-UBTVQH15.
Besides the ancient rock cave, what architectural structures make up Chùa Hang Pagoda today?
About 100 meters from the original cave entrance, the temple built an expanded three-story hillside structure: the first floor houses the kitchen and support quarters, the second floor is the Three Jewels Hall venerating Shakyamuni Buddha and Bodhisattvas, and the third floor is the Western Paradise Hall dedicated to Amitabha Buddha alongside Mother Goddess and Saint Trần altars. The grounds also preserve the Patriarch's ancient freshwater well and a monolithic blue-stone statue of Bodhidharma.
