The road up to the pagoda winds beneath a forest canopy, and if visitors arrive in winter, both sides of the trail are arched with liquidambar maple leaves turning red and gold. The pagoda sits on the slope of Tam Ban mountain with low roofs and a stone courtyard, backed by a stupa garden. Within that garden stands a stupa named Viên Thông, and nearby rests a blue-stone stele mounted on a tortoise base, its faces densely engraved with characters.
Erected in 1362, that stele records about five thousand characters chronicling the life of Second Patriarch Pháp Loa, the second patriarch of the Trúc Lâm Zen school. The stupa enshrines his relics. For that reason, practitioners of the Trúc Lâm lineage revere Thanh Mai as an ancestral seat, the resting place of the Second Patriarch and the site that preserves the primary epigraphic chronicle of his life.

IThe ancestral seat of Second Patriarch Pháp Loa
The Trúc Lâm Zen school is an indigenous Vietnamese Zen lineage founded in the late thirteenth century, led by three successive patriarchs, namely Trần Nhân Tông as First Patriarch, Pháp Loa as Second Patriarch, and Huyền Quang as Third Patriarch. Each left his deepest imprint in a distinct locale. The founding of the school on Yên Tử mountain, the Quỳnh Lâm academy where Pháp Loa lectured at the Trần-dynasty complex in Đông Triều, and the Third Patriarch's seat at Côn Sơn Pagoda are covered in those three entries. This entry focuses on Thanh Mai, the sanctuary that holds the stupa and stele of the Second Patriarch.
According to the stele inscription cited by Heritage World (Thế Giới Di Sản) and VnExpress, Second Patriarch Pháp Loa bore the secular name Đồng Kiên Cương (written Đồng Kim Cương in both articles) and was born on the 7th day of the 5th lunar month of the Giáp Thân year, Thiệu Bảo 6 (1284), in Đồng Hòa village, Cửu La township, Nam Sách Giang (in the area of former Hải Dương city). He entered monastic life under Buddhist Emperor Trần Nhân Tông in 1304 and officially succeeded as Second Patriarch of Trúc Lâm on the 1st day of the 1st lunar month of Hưng Long 16 (1308). Over more than twenty years at the helm of the Trúc Lâm Sangha, he trained over thirty eminent disciples, ordained and nurtured some fifteen thousand monks and nuns, oversaw the casting of more than one thousand three hundred statues, and established over two hundred monasteries and study centers according to Hải Phòng Newspaper and Heritage World. In 1329, one year before his passing, he expanded the mountain precinct of Thanh Mai according to Nhân Dân newspaper. On the 3rd day of the 3rd lunar month of 1330, he passed away at Quỳnh Lâm Monastery, and his relics were brought to be enshrined in Viên Thông Stupa behind Thanh Mai Pagoda.
Trúc Lâm differs from later Zen lineages in Vietnam in two fundamental ways. The first is its origin, since the Lâm Tế (Linji) and Tào Động (Caodong) schools entered Vietnam from China, whereas Trúc Lâm was founded by a Vietnamese king who renounced the throne, taking the mind as root and teaching engaged practice in the midst of worldly life. The second is its mode of transmission, as Trần-dynasty Trúc Lâm passed the Dharma seal directly from master to certified disciple without using a generational Dharma-name gāthā like later Lâm Tế branches. Consequently, at Thanh Mai there is no generational verse chart to consult, only the direct succession of the Three Patriarchs.
Many visitors assume that Patriarch Pháp Loa passed away at Thanh Mai. Historical sources record that he passed away at Quỳnh Lâm Pagoda and that his remains were then escorted to Thanh Mai for enshrinement. Another common misconception is to confuse Thanh Mai with a modern Trúc Lâm Zen monastery. The monasteries bearing the name Trúc Lâm built in recent decades belong to the modern revival movement, whereas Thanh Mai is an authentic fourteenth-century sanctuary of Trần-dynasty Trúc Lâm attested by a contemporary stupa stele.
IIFrom Viên Thông Stupa to modern reconstruction
The name of the monk who first built a hermitage here has not been preserved in available sources, which note only that the temple dates from the Trần dynasty. The documented timeline begins clearly with Pháp Loa, who expanded the mountain monastery in 1329 and was enshrined here in 1330, followed by the erection of his stupa and stele. During the Restored Lê period, additional stupas and steles were erected. After falling into ruin over a long period, the pagoda began to be restored step by step from 1980. According to Tiền Phong newspaper, when Venerable Thích Chí Trung arrived as abbot in 1994, the mountain site still lacked electricity, running water, and a road, so the monk and lay Buddhists carried building materials on their backs to cut a two-kilometer trail through the forest and rebuild the front hall, ancestral hall, and guest house before completing the main hall around 2005.

On July 12, 2025, the pagoda became a component site of the Yên Tử, Vĩnh Nghiêm, Côn Sơn, Kiếp Bạc UNESCO World Heritage property.
Sources give two different dates for the erection of Viên Thông Stupa, with Quảng Ninh Newspaper and Mekong ASEAN recording 1334 (four years after the Patriarch's passing, in accordance with his final testament) and Hải Phòng Newspaper recording 1330. Regarding the year the 1362 stele was recognized as a National Treasure, Prime Minister's Decision No. 2496/QĐ-TTg was signed on December 22, 2016 (as documented by the Chí Linh Đồng Clan portal and Tiền Phong newspaper), while several press outlets such as VnExpress reported on the announcement ceremony in early 2017 and thus cited 2017.
In 2021, archaeological excavations uncovered three previously unknown satellite sites along the slope of Phật Tích mountain behind the present pagoda, designated Thanh Mai 2, 3, and 4, yielding nearly one thousand artifacts across three overlapping architectural strata from the Trần, Restored Lê, and Nguyễn dynasties according to Nhân Dân newspaper. Hải Phòng Newspaper notes that the Thanh Mai 2 site lies about 400 meters from the current pagoda. These findings demonstrate that the Trần-dynasty monastery complex at Thanh Mai was far more extensive than the compound seen today.
IIIStupas, steles, and the pagoda in the forest
The pagoda building seen today is the result of reconstruction phases from 1980 through the 2000s. According to the Chí Linh Đồng Clan portal, the sanctuary follows a T-shaped (Đinh-character) ground plan consisting of a seven-bay front hall and a three-bay rear sanctuary housing jackfruit-wood Buddha statues. The oldest historical remains lie not inside the main hall but in the stupa garden and stele pavilion behind the temple. Visitors seeking authentic Trần-dynasty traces at Thanh Mai should walk straight to the rear garden.
Enshrines the relics of Second Patriarch Pháp Loa behind the pagoda, erected in 1334 (or 1330 depending on the source) and restored in 1714.
Erected in 1362 (5th year of the Đại Trị reign) from monolithic blue stone resting on a tortoise base. Its forehead is carved with Trần-style dragons, its borders with scrolling chrysanthemums, and its base with stylized waves. Both faces are engraved with about five thousand Chinese characters in clerical (lệ thư) and seal (triện thư) scripts, composed by attendant Trung Minh and collated by Third Patriarch Huyền Quang.
According to VnExpress, alongside Viên Thông Stupa behind the pagoda stand Phổ Quang Stupa (1702) and Linh Quang Stupa (1703) from the Restored Lê period together with five other ancient stupas.
Erected in 1718 during the Restored Lê period, a later commemorative stele recording the Patriarch's stupa alongside the temple's other historic steles.
Regarding the dimensions of the 1362 stele, Heritage World and VnExpress record the stele body as 131 cm high, 82 cm wide, and 14 cm thick, set upon a stone tortoise measuring 165 cm long, 103 cm wide, and 30 cm high. Tiền Phong newspaper describes the stele as standing over two meters tall, likely estimating the combined height of the slab, tortoise, and pedestal, so the library records both the exact survey measurements from Heritage World and VnExpress and the general description in Tiền Phong. The total count of ancient steles at the pagoda also varies between sources, with the Chí Linh Đồng Clan portal listing seven Trần- and Lê-dynasty steles and Nhân Dân referring to a system of four steles dating from the fourteenth to seventeenth centuries.
The extraordinary value of the 1362 stele lies in its primary historical text, engraved just thirty-two years after Pháp Loa's passing. According to VnExpress and Heritage World, the front face chronicles Pháp Loa's biography and the Trúc Lâm genealogy, while the reverse records major Trần-dynasty Buddhist undertakings in detail, including the casting of the Thousand-Armed, Thousand-Eyed Avalokiteśvara statue in Đại Khánh 8 (1321), monks and King Trần Anh Tông pricking their blood to print more than five thousand fascicles of the Tripitaka (Đại Tạng kinh) housed at Quỳnh Lâm Institute, the woodblock printing of nearly five hundred copies of the Four-Part Vinaya (Tứ Phần Luật), and the names of contemporary royal patrons, officials, and administrative territories. In a country where most Trần-dynasty books were lost to war and climate, this intact stone inscription serves as an irreplaceable primary chronicle and is recognized as a National Treasure.
IVThe lie of the land and orientation
This section presents the library's reading through the lens of traditional geomancy, not a doctrine recorded on the stele or in temple texts. The Thanh Mai stele records that Pháp Loa expanded the mountain precinct, but the sources consulted by the library do not state what geomantic method was used or give a compass bearing for the main hall. The library notes this clearly so that readers can distinguish historical documentation from geomantic interpretation.
The pagoda sits on the slope of Tam Ban mountain, historically called Phật Tích mountain, at an elevation of roughly two hundred meters. This is a classic mid-slope configuration, backed by a high crest serving as a rear pillow (hậu chẩm), with the ground sloping gently down toward the valley in front and flanked on both sides by secondary ridges curving like the arms of a throne. In mountain geomancy, a relatively level terrace midway up a slope marks the spot where the mountain vein pauses and gathers qi, and Trần-dynasty Zen monasteries consistently favored such terraces.
A second layer is the forest. VnExpress notes that the pagoda is surrounded by a natural liquidambar maple forest covering more than one hundred hectares. Dense forest retains water, stabilizes soil, and buffers wind, giving the stupa garden behind the temple a deep stillness rarely found at lowland pagodas. For a sanctuary whose foremost duty is guarding the Patriarch's stupa and stele, that stillness matters more than a wide front bright hall (minh đường).
A third layer is the placement of the stupa. Viên Thông Stupa stands behind the pagoda on higher ground following the rise of the mountain. Traditional thought assigns high, sheltered ground to ancestral rest and lower ground near the trail to the study and practice of the living. Pilgrims ascending the mountain pass through the main Buddha hall before reaching the stupa garden, naturally moving in proper sequence from the Buddha to the Patriarchs. Finally, the newly excavated Thanh Mai 2, 3, and 4 sites along the mountain trail toward Yên Tử show that ancient Thanh Mai did not stand in isolation but lay along a continuous mountain corridor linking the Trúc Lâm sanctuaries into a single spiritual landscape.
VMemorial festival of Patriarch Pháp Loa and annual observances
The pagoda's largest annual festival coincides with the memorial day of the Second Patriarch. According to Tiền Phong newspaper and the Chí Linh Đồng Clan portal, the Thanh Mai Pagoda festival takes place from the 1st to the 3rd day of the 3rd lunar month, with the 3rd marking the day Pháp Loa passed away in 1330.
| Lunar date | Festival | Description |
|---|---|---|
| 1st to 3rd day of the 3rd month | Thanh Mai Pagoda Festival and Memorial of Patriarch Pháp Loa | The largest annual festival at the temple, commemorating the Second Patriarch of Trúc Lâm at the pagoda and Viên Thông Stupa. |
| 15th day of the 1st month | Thượng nguyên (First Full Moon) | New Year prayer assembly for peace following Northern Vietnamese Buddhist custom. |
| 15th day of the 4th month | Buddha's Birthday (Phật Đản) | Celebration of the birth of Shakyamuni Buddha. |
| 15th day of the 7th month | Vu Lan (Ullambana) | Festival of filial piety in the Northern Buddhist tradition. |
| 1st day of the 11th month | Memorial of Buddhist Emperor Trần Nhân Tông | A major commemorative day across the entire Trúc Lâm lineage, with central ceremonies held at sites associated with the First Patriarch. |
Outside the third-lunar-month festival, the pagoda draws the most visitors during the final weeks of the solar year when the maple forest turns red and gold. Pilgrims following the trail of the Trúc Lâm school often combine Thanh Mai with Côn Sơn and the Trần-dynasty sites in Đông Triều on a single journey to visit the seats of all three patriarchs.

Thanh Mai is an active ancestral pagoda located within a protected forest, so visitors should observe both temple etiquette and forest conservation rules. Dress modestly and walk and speak quietly in the Patriarch's stupa garden. Because the 1362 stele is a National Treasure, please do not touch the stone face, sit on the tortoise base, or make ink rubbings. Do not break branches or pick maple leaves, and carry all litter back down the mountain.

Who is venerated at Thanh Mai Pagoda?
The pagoda worships the Buddha according to Northern Vietnamese Buddhist custom and serves as the ancestral seat of Second Patriarch Pháp Loa (secular name Đồng Kiên Cương, 1284 to 1330), the second patriarch of the Trúc Lâm Zen school. He passed away in 1330 at Quỳnh Lâm Institute, and his relics were brought to be enshrined in Viên Thông Stupa behind Thanh Mai Pagoda.
What is the Thanh Mai Viên Thông tháp bi stele?
It is a stone stele erected in 1362 (5th year of the Đại Trị reign), composed by attendant Trung Minh and collated by Third Patriarch Huyền Quang, engraved with about five thousand Chinese characters detailing Patriarch Pháp Loa's life and Trần-dynasty Buddhist affairs. The slab measures 131 cm high atop a tortoise base and was recognized as a National Treasure by Prime Minister's Decision on December 22, 2016 (some press reports covering the early 2017 ceremony cite 2017).
When was Viên Thông Stupa at Thanh Mai Pagoda built?
Sources give two dates. Quảng Ninh Newspaper and Mekong ASEAN record 1334 (four years after the Patriarch's passing), while Hải Phòng Newspaper records 1330. The stupa was repaired in 1714.
