Climbing to the top of the dike slope and turning down, visitors encounter a brick-paved courtyard and a ceremonial gate looking straight out toward the surface of the Red River. The communal house stands on an elevated earthen mound roughly half a hectare wide, its front facing north toward the flowing water. Vietnamese communal houses almost always face south, so that orientation alone signals that this place follows a way of its own.
That distinct character also lies in a feat rarely seen in the history of traditional Vietnamese architecture. When the dike surface was built higher and the communal house foundation became lower than the dike, the villagers neither dismantled the building to reconstruct it nor abandoned it to the floodwaters. They lifted the entire communal house 2.4 meters higher, keeping its hundreds-of-tons timber frame intact using only levers, hemp ropes, and everyday farming tools.
IThe Saint of Chèm
The communal house worships Lý Ông Trọng, whose real name is recorded as Lý Thân, a native of Chèm village venerated under the title Hy Khang Thiên Vương and affectionately called by locals in three words as Đức Thánh Chèm (the Saint of Chèm). Worshipped alongside him in the sanctuary are his consort, Royal Consort Bạch Tĩnh Cung (a princess of the Qin dynasty), together with Ông Sứ (the benefactor who healed the Saint) and the Six Royal Children (Lục vị Thánh Vương tử, four princes and two princesses).
This represents the worship of a human deity (nhân thần) in Vietnamese folk belief, honoring a figure recounted in legend as a historical person who was later canonized as a village tutelary deity (thành hoàng). The sanctuary does not belong to any institutionalized religion with a central clergy, and ritual affairs are managed by the village. People commonly refer to the site by both names, Chèm Communal House (đình Chèm) and Chèm Temple (đền Chèm), because the complex serves both as the communal hall of the village and as a shrine to a saint whose stature reaches far beyond the boundaries of a single village.
According to the sacred biographies (thần tích), Lý Ông Trọng possessed extraordinary stature, traveled north to assist the Qin dynasty against the Xiongnu, married Princess Bạch Tĩnh Cung, resided there for a period, and eventually returned to his homeland. What the local accounts emphasize at home is not merely his physical strength but the work he performed for the people, including subduing a water monster in the river stretch before the village, promoting agriculture (khuyến nông), and encouraging sericulture (khuyến tang), teaching the populace how to farm rice, raise silkworms, and weave cloth. Tradition also records that after his passing, King Thục Phán An Dương Vương permitted the people of Thụy Phương commune to establish a temple in his honor.
Because his mission in the North is recounted in terms of diplomatic relations rather than military conquest, later generations came to call him the first diplomat in Vietnamese history. That appellation is a tribute coined by posterity for a legendary figure rather than an official title recorded in dynastic annals.
From a documentary standpoint, the chronological era of this figure's life is recorded differently across sources. The heritage dossier places him in the reign of An Dương Vương. Several other documents state that he was born toward the end of the reign of Hùng Duệ Vương and passed away during the reign of Thục An Dương Vương. That discrepancy lies within the realm of a legendary stratum rather than a fixed annalistic date, so the library records both accounts without choosing arbitrarily.
What can be verified with greater certainty is the layer of material heritage preserved inside the communal house, including Nguyễn dynasty royal investiture edicts, parallel couplets, a bronze bell, an agarwood incense burner inscribed with a prose composition by Doctorate holder Lý Trần Quán dated the 53rd year of Cảnh Hưng (1774), and ten worship statues. In the inner sanctuary stand two red-lacquered and gold-gilded wooden statues carved in 1888 on lotus stone pedestals, namely the statue of Saint Lý Ông Trọng measuring two trượng high (roughly three to four meters) and the statue of Royal Consort Bạch Tĩnh Cung measuring over 1.8 trượng high.
To clarify a frequent misunderstanding from a historical perspective, Chèm Communal House is often introduced as a communal house more than two thousand years old, and many people take that number to mean the age of the wooden building standing before their eyes. Others mistake the years 1748 and 1756 for the construction dates of the wooden frame.
That is not the case. The figure of more than two thousand years refers to the age of ritual veneration on this site, counted from the legendary milestone of establishing a shrine during the reign of An Dương Vương. The extant architecture bears the artistic imprint of the 17th to 19th centuries through the construction of the inner sanctuary in 1631, the repair of the ceremonial gate in 1773, the major restoration of the inner sanctuary in 1792, and subsequent renovations in 1797, 1885, 1902 to 1903, and 1913. Meanwhile, the two dates 1748 and 1756 (under King Lê Hiển Tông), along with 1824 (under King Minh Mạng), are the years when the solid bronze rain gutter system placed between the roof eaves was cast.
IIFrom the old foundation to the lifting of the communal house
The history of the communal house is the history of a tug-of-war with water. The village sits right against the right bank of the Red River, and each generation built the river dike a little higher. Every time the dike surface rose, the communal house foundation sank lower in relative terms, until a moment came when the village had to choose between abandoning the ancestral ground or lifting the communal house upward.
- Reign of An Dương VươngFounding of the templeAccording to legend, after Lý Ông Trọng passed away, the king permitted the people of Thụy Phương commune to erect a temple honoring him in the village. This is a legendary milestone rather than an annalistic date.
- 1631Construction of the inner sanctuary under Revival LêAccording to architectural history records, the inner sanctuary (hậu cung) of the communal house was first constructed in 1631.
- 1748 and 1756Casting of the bronze rain gutter system under Lê Hiển TôngVillagers cast a solid bronze rain gutter system placed at the junctions of the roof eaves in 1748 and 1756, with an additional casting in 1824 under King Minh Mạng.
- 1773 and 1792Ceremonial gate repair and major sanctuary restorationThe ceremonial gate was repaired in 1773, followed by a major restoration of the inner sanctuary in 1792 and renovations in 1797 and 1885.
- Early 20th centuryLifting the communal house 2.4 meters highVillagers jacked up the entire communal house level with the dike using farming tools under the direction of Master Vương Văn Địch of Văn Trì village. Sources record different years (1902, 1903, 1916, or 1917), detailed immediately below.
- 1990National heritage site rankingThe communal house was recognized by the Ministry of Culture and Information as a national historical and cultural heritage site.
- 2016 and 2017National Intangible Heritage and Special National Heritage SiteThe Chèm Communal House Festival was inscribed on the National List of Intangible Cultural Heritage under Decision No. 2067/QĐ-BVHTTDL dated June 13, 2016. Chèm Communal House was ranked a Special National Architectural and Artistic Heritage Site under Decision No. 2082/QĐ-TTg dated December 25, 2017.
Where sources diverge, the library states the differences plainly. Regarding the year the communal house was lifted, many documents record that the elevation work began in 1902, lasting one year under the direction of Master Vương Văn Địch (a native of Văn Trì village) at a cost of 500 Indochinese silver piastres. Dân Trí newspaper, citing village elders, records that the lifting took place in 1903. Meanwhile, the heritage dossier of the Department of Cultural Heritage states that the 2.4-meter elevation occurred in the Bính Thìn year, namely 1916, while another press report gives 1917 in connection with a dike breach. Because those figures span more than a decade, the library records all accounts rather than choosing one arbitrarily. What every source agrees upon is the exact height raised, 2.4 meters.
Regarding the ranking decision number for the special national heritage site, the official document signed by the Prime Minister is Decision No. 2082/QĐ-TTg dated December 25, 2017 (a few local news pages previously mistyped the number as 2028/QĐ-TTg).
IIIInner Công and outer Quốc layout by the river
The communal house is laid out in the inner Công, outer Quốc (nội công ngoại quốc) plan, meaning the interior halls form the shape of the character Công (工) while the surrounding corridors enclose them in the shape of the character Quốc (国). This is a layout typical of grand ceremonial complexes, rarely seen in a village communal house, and it speaks to the stature this sanctuary once held across the region.
The outermost gate looking toward the river, topped with pillars sculpted with sacred animals facing the four directions. This forms the boundary between the riverbanks and the communal house grounds.
The second gate built in a multi-tiered stacked-roof (chồng diêm) style with multiple entryways, repaired in 1773. The two gates are linked by a courtyard that slows a visitor's pace before entering the worship precinct.
Two side wings flanking the courtyard together with an eight-roofed square pavilion (phương đình) in the center, where ritual offerings are arranged and village associations (giáp) stand during festivals.
The main five-bay, two-side-chamber hall with multi-tiered stacked roofs. Notably, its truss system relies on interlocking horizontal beams (con rường) rather than a dense forest of supporting columns, making the interior much more spacious than a typical communal house.
The connecting incense hall (ống muống / thiêu hương) and the innermost sanctuary housing the dragon throne, ancestral tablets, and red-lacquered, gold-gilded wooden statues carved in 1888. Between the roof eaves runs a solid bronze rain gutter system cast in 1748, 1756, and 1824.
A system of stone railings carved with dragon-and-cloud motifs enclosing the inner courtyard. Stone and timber standing side by side here mark successive layers of restoration over the centuries.
Woodblock carvings
The woodcarvings at Chèm Communal House bear the strong artistic style of the 17th and 18th centuries. Their themes span dragons, phoenixes, and the four sacred animals (tứ linh), alongside classic northern Vietnamese communal house motifs such as a phoenix holding a scroll (phượng ngậm thư) and a carp transforming into a dragon (cá chép hóa rồng). Interwoven among the sacred creatures are cloud scrolls, bats symbolizing blessings (phúc), turtles, and cranes.
What rewards a close viewer is the craftsmanship. Within a single hall, master carpenters employed multiple carving techniques side by side, including openwork carving (chạm lộng) to create deep spatial layers, relief carving (chạm nổi) for panels requiring clear contours, and high-relief undercutting (chạm bong kênh) where figures leap free from the timber surface. Standing beneath a single roof truss and recognizing all three techniques working together is how one reads communal house woodcarving properly, rather than merely glancing at the whole and offering general praise.
Regarding the Chinese characters (瑞芳亭), the library records the three characters read according to the literary name of Thụy Phương commune, inferred by the library rather than transcribed directly from a horizontal plaque or gate board. Visitors who read the characters directly on site artifacts should take the inscriptions on the artifacts as standard.
IVThe lie of the land and orientation
This section presents the library's reading through the lens of traditional geomancy (phong thủy), not content transcribed from stone stelae or the official heritage dossier. The library states this clearly so readers can distinguish between historical documentation and interpretive reading.
The most noteworthy feature here is the orientation. Vietnamese communal houses take the south as their standard orientation because facing south welcomes the cool summer breeze and shields against the winter north wind, so much so that the proverb marry a gentle wife, build a house facing south became household wisdom. Chèm Communal House, however, faces north, reversing the convention. In traditional land reading, whenever a monument foregoes the advantages of a southern orientation to turn toward another direction, it is always because something in that direction is far more valuable. Here, that feature is the Red River.
Read in the classical way, the vast expanse of water before the gate serves as the bright hall (minh đường), and the wider the bright hall, the more abundantly it gathers qi. The Red River along this reach is not a small pond dug before a courtyard but a mighty river current, the kind of bright hall that inland villages have to dig a crescent pond to imitate. Furthermore, the deity venerated inside is the very figure linked in sacred biography to subduing water monsters along this exact stretch of river. A deity of the water faces the water, and that unusual northern orientation becomes the fitting one.
Second is the footing. The communal house sits on a high earthen mound roughly half a hectare wide rather than down on the flat floodplain. In traditional thought, a mound rising amid low-lying fields is read as a turtle back, providing a firm support even where no mountains surround the area. The entire village of Chèm lies behind the communal house, meaning the shrine takes the cluster of village homes as its rear pillow (hậu chẩm) while opening its front completely toward the river. That is the spatial arrangement of a village that lives in harmony with the river rather than turning its back to it.
Third, and most distinctive to this site, is the dike. As the dike was built higher over generations and its crown rose above the communal house floor, the lie of the land was inverted, with the bright hall blocked by an earthen embankment while the worship foundation sat sunken like the bottom of a basin. By classical rules, when the node (huyệt) lies lower than the front screen (án), its qi is suppressed. The villagers' feat of lifting the entire communal house 2.4 meters to match the dike level was therefore more than flood protection. It restored the sacred foundation to its proper elevation so that the communal house could once again behold the river and the river could behold the communal house.
Finally, ritual and land are read together. The grandest festival of the year does not take place entirely within the courtyard walls, as a fleet of boats rows out to midstream to draw pure water before carrying it back in procession. In traditional reading, once each year the community goes straight out to the bright hall (minh đường) to invite the vital qi back to the altar. The lie of the land here does not sit still on a map, it is reenacted as a living rite.
VThe Chèm Festival on the full moon of the fifth lunar month
The festival opens around the full moon of the fifth lunar month, typically lasting three days with the full moon (the 15th) as the main feast day. This is one of the few major riverside festivals along the Red River held in mid-summer, uniting three ancient sworn brother villages along the riverbank, Chèm (Thụy Phương), Liên Mạc, and Hoàng Xá, and every major solemn rite revolves around water. The Chèm Communal House Festival was inscribed on the National List of Intangible Cultural Heritage under Decision No. 2067/QĐ-BVHTTDL dated June 13, 2016.
| Lunar timing | Rite | Description |
|---|---|---|
| Before the main feast | Bathing rite (Lễ mộc dục) | Bathing the sacred statues and wiping ritual implements with fragrant water, performed in private inside the inner sanctuary by senior elders of the ritual committee. |
| Opening day | Water procession (Lễ rước nước) | A fleet of flower-bedecked dragon boats leaves the landing, rowing upstream along the Red River to draw pure water from midstream and carry it back to the communal house for the bathing rite and offerings. This is the most solemn rite of the festival. |
| 15th of the 5th lunar month | Main feast and text procession | Grand sacrificial ceremony at the Great Worship Hall and inner sanctuary, procession of ceremonial texts and votive offerings, attended jointly by the three sworn brother villages (Thụy Phương, Liên Mạc, Hoàng Xá) in their time-honored order. |
| During the festival | Sweet mung bean pudding contest (Thi làm chè kho) | A competition among village associations (giáp) to cook sweet mung bean pudding (chè kho) from green beans, sugar, and pork fat. Once finished, the pudding is offered upon the altars of the Saint and the Royal Consort before being shared. |
| During the festival | River and riverbank folk games | Boat racing, duck catching, tug-of-war, kite flying, and releasing doves, mostly held right on the riverbank before the communal house. |
To state a point where sources differ, regarding the festival dates, some documents record that the festival runs from the 14th to the 16th of the fifth lunar month, while others record from the 15th to the 17th. Both accounts take the full moon (the 15th) as the principal day, differing only on whether the opening day is counted before or on the full moon. The library records both.
Outside the fifth-month festival, the communal house maintains regular incense offerings on the first and fifteenth days of each lunar month, tended by the village ritual committee (ban khánh tiết).
VILocation And How To Get There

This is an active place of worship rather than a museum, so house customs should be respected. Standard reminders on site include dressing modestly, removing hats when entering the interior halls, walking softly and speaking quietly near the inner sanctuary, and refraining from touching worship statues, stone balustrades, and carved wooden components. Offerings should be placed on the proper altars and donations in the merit box. During the three-day fifth-month festival, the water procession on the river is carried out by the ritual committee and local villagers, while visitors watch from the riverbank.

?Quick Questions
Whom does Chèm Communal House worship?
It worships Lý Ông Trọng, whose real name is Lý Thân, a native of Chèm village venerated under the title Hy Khang Thiên Vương and popularly called Đức Thánh Chèm (the Saint of Chèm). Also worshipped inside are his consort Royal Consort Bạch Tĩnh Cung (a Qin dynasty princess), Ông Sứ, and the Six Royal Children. This represents the worship of human deities in Vietnamese folk belief and does not belong to any institutionalized church.
Is Chèm Communal House really more than two thousand years old?
The figure of more than two thousand years refers to the age of ritual worship on the site, counted from the legendary founding of the shrine under An Dương Vương. The standing timber architecture bears the artistic imprint of the 17th to 19th centuries (inner sanctuary built in 1631, major restoration in 1792), alongside a solid bronze rain gutter system cast in 1748, 1756, and 1824.
What is the story of lifting Chèm Communal House higher?
When the Red River dike was built higher than the communal house floor, villagers lifted the entire communal house 2.4 meters to match the dike level under the direction of Master Vương Văn Địch of Văn Trì village, keeping the timber frame intact using only levers, hemp ropes, and farming tools. Sources record different years for the feat, including 1902, 1903, 1916, and 1917.
Why does Chèm Communal House face north?
Because the communal house takes the Red River as its front expanse. Vietnamese communal houses normally face south, but here the great river flows to the north, and the deity venerated inside is linked to subduing water monsters along that very stretch of river. This is the library's geomantic reading, clearly noted in the article.
When is the Chèm Communal House Festival held?
Around the full moon of the fifth lunar month, typically lasting three days with the 15th as the main feast day. Sources record the three-day span differently, either the 14th to the 16th or the 15th to the 17th. The centerpiece rite is the water procession in midstream on the Red River, alongside the statue-bathing rite, the sweet mung bean pudding contest, and riverbank folk games.
