Looking across from the village road of Bằng An, you see a dark red brick mass tapering toward the sky, not square-cornered like other Cham towers you may have encountered, but unusually rounded in silhouette. Only upon walking closer can you count its faces, eight equal wall planes, each roughly four meters wide, laid with bricks fitted so tightly that the eye cannot find a mortar joint. Before the entrance sit a pair of sandstone guardians with elephant heads, lion bodies, and bells around their necks.
This is Bằng An Tower (tháp Bằng An), a Cham Hindu sanctuary dedicated to Shiva, erected around the 11th century in the territory of Amaravati. Among all surviving Cham towers in Vietnam, it is the only one built on an octagonal ground plan. That unusual silhouette was not chosen merely for visual effect, as the entire tower mass was fashioned in the form of a large linga, the sacred emblem of Shiva himself rising from the plain.
IShiva and a temple tower shaped like a linga
Bằng An Tower is dedicated to Shiva in the form of the linga. Inside the main sanctum once stood a stone linga ensemble, of which only the lower pedestal remains today. Published sources consistently interpret the octagonal body tapering upward to its rounded peak as a monumental representation of the linga, tied to the Shaivite worship of the linga and yoni. In other words, the sacred emblem here was not merely housed inside the sanctuary, as the entire tower itself took on the shape of the sacred emblem.
In Shaivite doctrine, a linga is not a portrait statue of the deity, but the sign of his presence, an upright cylindrical pillar set upon a grooved yoni pedestal that channels sanctified water. The linga embodies the generative principle while the yoni represents divine creative energy, joined together as an inseparable pair. A detailed explanation of this iconographic pair appears in the entry on Mỹ Sơn Sanctuary.
What sets Bằng An apart is how it translates that theological idea into architectural mass. At most Cham temples, the linga rests inside the dim sanctum while the outer tower represents the cosmic mountain Meru. At Bằng An, a viewer approaching from afar sees the silhouette of a linga even before stepping through the doorway.
Historical documentation requires a measured note. No foundation stele has been published recording who built the tower or in what exact year. One press article links the construction to a specific Cham king without citing an inscription, and the reign of that monarch does not match the 11th-century date stated in the same article, so the library does not name a founding king. Likewise, art historians have not assigned this monument to a standard named architectural style with a clear source citation. Its octagonal form stands in a class of its own, and the library leaves it as such.
One common misconception should be cleared up. Seeing the rounded, tapering silhouette of the monument, many visitors assume it is a funerary stupa or a bell-shaped Buddhist tower. It is neither. Bằng An is a Cham Hindu sanctuary dedicated to Shiva, complete with an inner sanctum, a linga pedestal, and a main entrance opening to the east like other kalans. The principal Buddhist center of the Cham in the Quảng region stood elsewhere at Đồng Dương Buddhist Monastery.
IIA solitary tower standing across a millennium
Bằng An does not belong to a multi-tower valley sanctuary like Mỹ Sơn, nor was it a royal capital. It stands as a single isolated temple on the lower plain of the Thu Bồn River, roughly 6.7 kilometers from Trà Kiệu, the site of the former capital Simhapura, and about 18.4 kilometers from Mỹ Sơn. Its documented history is consequently brief and consists largely of conservation efforts.
- Around 11th centuryConstruction of the towerDated by architectural form rather than a foundation stele. The sanctuary belonged to the Amaravati region of Champa.
- 1940 or 1943French restoration of the vestibuleFrench archaeologists restored the monument and converted the two secondary side doorways of the vestibule into two windows. Dân Việt gives the year 1940, while Thanh Niên gives 1943.
- 1989National heritage siteOn January 21, 1989, the Ministry of Culture issued Decision 100-VH/QĐ ranking Bằng An Tower as a national architectural and artistic heritage site.
- December 2023Conservation project approvedAccording to Nhân Dân newspaper, former Quảng Nam province approved a conservation project of over 8.3 billion VND to prevent structural deterioration.
- 2025Adjusted restoration projectAccording to Báo Đà Nẵng, on April 1, 2025 former Quảng Nam province approved nearly 8.4 billion VND to reinforce and restore the tower and auxiliary works, subsequently extending the schedule into 2026.
- 2026 to 2027Restoration work and park proposalThe completion target for the conservation project was adjusted to the 2026 to 2027 period alongside a local proposal to plan a 4-hectare Bằng An Tower Park.
Where sources differ on four specific points, the library records each side.
Construction date. Dân Việt and Thanh Niên date the tower to around the 11th century, Nhân Dân gives around the 10th century, and Báo Đà Nẵng gives around the 12th century. All three are architectural estimates in the absence of a stele. The library uses the 11th century as the most widely cited benchmark while noting that it represents an approximate range rather than a fixed year.
Year of the French restoration. Dân Việt reports that the French restored the vestibule and turned its two side doorways into windows in 1940, whereas Thanh Niên states that this restoration took place in 1943.
Height. Dân Việt and Thanh Niên record a total height of 21.5 meters (with the main sanctuary rising nearly 21 meters), while Nhân Dân records nearly 20 meters.
Recent conservation project. Nhân Dân reports a conservation budget of over 8.3 billion VND approved in December 2023. Báo Đà Nẵng reports nearly 8.4 billion VND approved on April 1, 2025, initially scheduled for 2023 to 2025 and later extended into 2026, while Thanh Niên cites an expected completion in 2027. These figures reflect successive administrative adjustments to the same conservation project.
IIIEight brick faces and an eastern vestibule
The monument consists of two connected parts aligned along an east-west axis, a vestibule (tiền sảnh) in front and a main sanctuary (điện thờ) behind. The long vestibule rests on a base 3 meters high, opens its main entrance to the east, has two former side doorways on its flanks that were modified into windows, and is roofed by a pyramidal vault formed by four curved faces tapering to a peak. The main sanctuary behind it is a tall octagonal tower divided into three vertical sections, a base, an octagonal body, and a pyramidal roof formed by eight curved faces tapering gradually to the summit, housing the chamber where the stone linga ensemble once stood.
The main sanctuary has eight equal wall planes, each 4 meters wide, with flat unadorned brick walls lacking false doors, wall pilasters, or surface floral carvings. Standard Cham kalans have a square ground plan.
Extending eastward on a 3-meter-high base, the vestibule leads worshipers from the sunlit exterior into the dim sanctum. Its main doorway faces east, while two secondary side doorways were converted into windows by the French in 1940 (or 1943).
An octagonal interior chamber connected to the vestibule by a narrow passage, where the stone linga ensemble was installed. The linga shaft is now gone, leaving only the lower pedestal.
The vestibule roof is a pyramid of four curved faces, while the main sanctuary roof is a pyramid of eight curved faces tapering to the apex, giving the tall tower the silhouette of a rounded cylinder from afar.
Made from local clay and laid so tightly that mortar joints are virtually invisible. The exact binding technique used by Cham masons remains an open scientific question.

Why an octagonal plan is so rare
A square ground plan is the standard layout of a Cham kalan because it naturally accommodates one real doorway and three false doors on the four cardinal faces while allowing square roof tiers to step inward evenly. Shifting to an eight-sided plan for the main sanctuary made bricklaying far more demanding, as the wall corners meet at obtuse 135-degree angles requiring custom-beveled corner bricks, and the tall corbeled vault above had to converge smoothly along eight curved planes toward the summit. The masons at Bằng An accepted that technical challenge and omitted exterior false doors and surface brick carvings so that the body and roof of the sanctuary would preserve a smooth cylindrical silhouette resembling a linga.
Every account of Bằng An remarks on how the tower has remained standing in nearly complete form for close to a thousand years. Yet that great age also explains why the monument requires repeated conservation. Weathering and cracking on the lower brickwork and vault prompted the recent 8.4-billion-VND conservation project, which focuses on reinforcing the base, sealing structural cracks, and preventing termite and moss damage to stabilize the structure without resurfacing its ancient brick skin.
IVThe lie of the land and orientation
Two distinct sets of rules must be separated before discussing the setting of Bằng An. The first belongs to the temple builders, as Hindu sanctuaries open their main doorway to the east to greet the rising sun, typically stand on elevated mounds, and relate symbolically to the cosmic mountain and sacred water. The second is traditional Vietnamese geomancy (phong thủy), a system neither taught by Hinduism nor practiced by the Cham. The reading below is offered by the library through that second lens for comparison alongside the first, and does not appear in any historical record of the monument.
Seen through the eye of traditional Vietnamese landform analysis, Bằng An stands in the configuration of a solitary peak (cô phong), a single tall structure rising alone across the flat lower plain of the Thu Bồn River without a backing hill behind it or companion towers beside it. Traditional geomantic manuals are often cautious toward a solitary peak exposed to winds from all four quarters. Yet for a sanctuary whose entire body embodies a linga, standing alone is appropriate, since the sacred emblem occupies the center by itself.
The second feature is the eastern orientation. In traditional East Asian geomancy, the east belongs to the Wood phase and corresponds to the rising vitality of morning. The Cham builders oriented the vestibule doorway to the east for a specifically Hindu liturgical reason, so that the first rays of morning sunlight would travel through the vestibule to touch the linga inside. The two traditions meet at the same compass bearing while following their own distinct reasoning.
The third feature is the number eight. Observers familiar with East Asian tradition looking at an eight-sided tower readily think of the Eight Trigrams (bát quái) and the eight compass directions. Hindu cosmology likewise recognizes the guardians of the eight directions (Ashtadikpala), one presiding over each quarter and intercardinal point. Even so, no source indicates that the builders of Bằng An chose an octagonal plan to represent the eight directions, as published studies connect the octagonal silhouette directly to the cylindrical form of the linga. The library notes the numerical parallel as a point of reflection rather than an established explanation.
Finally, there is the relationship with water. The land surrounding the tower consists of alluvial rice fields nourished by river water. Traditional Vietnamese siting regards a lowland plain encircled by water as ground that gathers qi. For the Cham, water was tied directly to the rite of bathing the linga, where liquid poured over the stone shaft flowed out along the yoni spout. Looking at the same element, the two traditions read two different meanings.
VLinga worship inside a single sanctuary
At Bằng An today no Cham community performs temple rites. The monument is preserved as an architectural heritage site with no active Cham festival calendar. The annual Katê festival of the Cham Balamon community is celebrated at active temples further south in south-central Vietnam, such as Po Klong Garai Towers. The table below reconstructs the historical rites legible from the physical layout of the tower itself.
| Rite | Practice | Material trace at Bằng An |
|---|---|---|
| Bathing the linga | The officiating priest poured water, milk, or scented oil over the crown of the linga, letting it drain out through the yoni spout. | The surviving linga pedestal inside the main sanctum. |
| Passing through the vestibule | Worshipers moved from the bright exterior through a transitional hall before approaching the inner sanctum. | The long eastern vestibule with its main doorway and two former side doorways (later modified into windows). |
| Offering flowers, incense, and lamps | Daily worship before the sacred emblem performed by an officiating priest. | The narrow octagonal sanctum chamber sized for the officiating priest standing before the linga. |
| Guarding the sacred threshold | Installing mythical guardian beasts at the entrance to protect the consecrated ground. | The pair of sandstone Gajasimha statues wearing neck bells outside the entrance. |
| Circumambulating the temple | Walking clockwise around the exterior of the sanctuary while keeping the temple on one's right. | The freestanding octagonal tower unblocked by adjacent structures. |
If visitors encounter burning incense at the foot of the tower today, that practice belongs to local Vietnamese residents in later times rather than a continuation of Cham linga liturgy. The two layers should be understood on their own terms without ranking one above the other.

?Quick Questions
Who is worshiped at Bằng An Tower
The Hindu deity Shiva is worshiped here in the form of the linga. Inside the main sanctum once stood a stone linga ensemble, of which only the lower pedestal survives. The tall octagonal tower tapering to its peak is itself interpreted by scholars as the form of a giant linga, linked to Shaivite linga and yoni worship.
Why does Bằng An Tower have an octagonal shape
Sources explain that the octagonal body and eight-sided curved pyramidal roof of the main sanctuary tapering toward the summit were fashioned in the likeness of a linga, the sacred emblem of Shiva, so that the entire tower embodies the object of worship. It is the only surviving Cham tower with an eight-sided body, each face measuring 4 meters wide, whereas standard Cham kalans have a square plan.
When was Bằng An Tower built
No foundation stele records the exact construction year. Dating is based on architectural style, and sources vary, with Dân Việt and Thanh Niên giving around the 11th century, Nhân Dân giving around the 10th century, and Báo Đà Nẵng giving around the 12th century. The 11th-century estimate is the most widely cited.
How tall is Bằng An Tower
Dân Việt and Thanh Niên record a height of 21.5 meters (with the main sanctuary rising nearly 21 meters), while Nhân Dân records nearly 20 meters. Each of the eight sides of the main sanctuary measures 4 meters wide, preceded on the east by a vestibule resting on a 3-meter-high base.
Where is Bằng An Tower located
In Bằng An village, An Thắng ward, Đà Nẵng city. Prior to the 2025 administrative reorganization, the site belonged to Điện An ward, Điện Bàn town, Quảng Nam province, which was merged with Điện Thắng Nam and Điện Thắng Trung to form An Thắng ward of Đà Nẵng city.
