From the outside, Thủ Thiện Tower looks like a miniature version of familiar Cham sanctuaries, a square brick shaft rising from a tall, slightly waisted base, a three-tiered roof, small corner towers at all four angles, and multi-layered pointed doorway arches. Visitors who merely walk around the base and leave will miss its most remarkable feature. Stepping through the eastern entrance into the inner chamber and letting the eyes adjust to the dimness, one should look straight at the western rear wall.
Carved into that wall is a recessed altar framed by a pointed-arch niche, a feature that the Ministry of Culture, Sports and Tourism notes has not been recorded in any other Champa monument. This is Tháp Thủ Thiện (Thủ Thiện Cham Tower), called Thủ Hương cổ tháp (Ancient Tower of Thủ Hương) in classical geographical records, a Cham Hindu temple-tower built in the first half of the 12th century near the southern bank of the Kôn River.
IVillage names, classical records, and an unconfirmed deity
Thủ Thiện is the name of the Vietnamese village, not the original Cham name of the sanctuary. The original Cham name, if one existed, has not been preserved in the sources consulted by the library. The monument is a temple-tower of Cham Hinduism, also known as Bàlamôn Cham, though its principal deity has not been confirmed by an in-situ inscription. Inside the chamber, no original cult statue or central pedestal remains in place, only numerous wall sockets showing where relief plaques were once mounted, while a 12th-century sandstone statue of the sacred bull Nandin reclining on a rectangular base was discovered in the temple grounds.
According to Hindu temple doctrine, the central emblem of a kalan stands in the middle of the inner chamber along the axis of the eastern doorway so that the early morning sunlight strikes it directly. The niche carved into the western wall at Thủ Thiện lies squarely on that axis, facing the entrance. Whether it served as a backdrop for the main emblem or held a secondary image remains unconfirmed by existing scholarship.
Regarding the name Thủ Hương cổ tháp, the portal of the Ministry of Culture, Sports and Tourism cites the Nguyễn dynasty geography Đại Nam nhất thống chí, which records that the Ancient Tower of Thủ Hương stood in Thủ Hương Hamlet, Tường Vân District, and was popularly called Tháp Đồng (the Bronze Tower). The monument was also surveyed in Henri Parmentier's Inventaire descriptif des monuments čams de l'Annam, published in France in 1909. In local folk verse from Bình Định, the tower appears in the couplet Steadfast stands the ancient tower, who built it, over there Thủ Thiện, over here Dương Long, pairing Thủ Thiện with Dương Long Towers about 2.9 kilometers away.
A frequent point of confusion involves the name Tháp Đồng (Bronze Tower). As scholar Ngô Văn Doanh notes in his book Tháp cổ Chăm Pa, sự thật và huyền thoại, cited by the Ministry of Culture, Sports and Tourism, Đại Nam nhất thống chí originally recorded Tháp Đồng as the vernacular name of Thủ Thiện Tower. Later, French researchers applied the name Bronze Tower (Tour de Cuivre) to Cánh Tiên Tower inside Đồ Bàn Citadel, while calling Thủ Thiện Tour de Bronze (translated as Bronze Tower or Brass Tower, Tháp Thau). The library notes this textual history so readers do not confuse the two monuments across different books.
IINine hundred years and successive restorations
The tower has no foundation stele. The Ministry of Culture, Sports and Tourism dates it to roughly the first half of the 12th century on stylistic grounds, grouping it with Cánh Tiên and Phú Lốc. That was the era when the political center of Champa stood at Vijaya, and the upper Kôn River valley where the tower stands formed the western reaches of that heartland.

- 1985Storm uproots the banyan tree on the roofBefore 1985, a giant banyan tree grew over the summit of the tower, which villagers dared not cut down out of reverence. A major typhoon in 1985 blew the tree off the roof while leaving the brick tower intact.

Sources diverge on two points. Regarding the ranking date, the library's data table follows the Ministry of Culture, Sports and Tourism in recording April 20, 1995, whereas Kifa Travel writes January 20, 1995. The library follows the Ministry's date. Regarding the construction period, the Ministry gives the first half of the 12th century, while Kifa Travel and Lữ Hành Việt Nam note that some studies place the tower in the 11th century or late 11th to 12th century, during the transition from the Mỹ Sơn A1 style to the Bình Định style. Both estimates rely on stylistic comparison.
As for conservation history, following initial work in 1992 to 1993 and roof reinforcement in 2019, the 2021 to 2025 restoration project advised by the National Institute for Monument Conservation used custom-fired bricks matching the original firing temperature, soaked in water, rubbed flat against one another by hand, and bonded with a mixture of bời lời resin and brick dust. This explains why visitors today see newly ground brick sections integrated with ancient brickwork on the roof and walls.
IIIThe arched altar niche inside the chamber
The tower stands on a square base platform measuring about 8.5 meters per side according to Kifa Travel. Thủ Thiện is smaller than Cánh Tiên and Phú Lốc but shares the silhouette of the Bình Định style, whose general characteristics are discussed in the entry on Bánh Ít Towers. Here the focus is on what belongs specifically to Thủ Thiện.
A tall base that narrows slightly at the middle and flares out at the foot and upper ledge, giving the compact shaft a steady stance.
Three upper tiers of similar form diminish toward the top. All four corners of each tier are ornamented with closely stacked miniature corner towers.
Spearhead arches rise in multiple overlapping layers, with the three false doors remaining relatively intact. The engaged pilasters are left plain, while the vertical panels between them project outward as bold ridges.
Numerous mounting sockets remain on the interior walls, marking where subsidiary relief plaques or icons were once attached.
A recessed surrounding altar carved deep into the western rear wall and framed by a pointed-arch niche. The Ministry of Culture, Sports and Tourism notes that no other Champa monument is known to have this feature.
What makes this altar niche remarkable is its placement. Cham master builders normally concentrated architectural ornament on the exterior, across doorway arches, pilasters, corner towers, and cornices. The interior chamber was typically left plain and dark as a housing for the deity rather than a space for visual display. At Thủ Thiện, the builders brought the pointed arch, the very form used for the exterior portals, inside the sanctuary and carved it into the rear wall. In effect, the silhouette of the temple doorway is repeated once more inside the heart of the shrine, directly opposite the entrance.
About 2.9 kilometers away stands Dương Long Towers, a monumental triad combining large carved stone blocks with brick. Though close neighbors, the two sites take opposite paths, one grand and outwardly expressive, the other compact and keeping its rarest detail hidden within.
IVThe lie of the land and orientation
Two distinct frameworks should be kept separate here. The first is the rule of the temple builders, under which a Hindu sanctuary opens its main doorway faces east toward the rising sun, takes the tower mass itself as a sacred mountain, and pairs the shrine with high ground and water. Hinduism does not teach feng shui, and the Cham chose the site by their own sacred canon. The second is a comparative reading by the library through traditional East Asian geomancy, offered for readers familiar with Vietnamese spatial habits rather than as anything recorded in Cham texts.
Thủ Thiện stands on a low mound amid relatively flat terrain near the southern bank of the Kôn River, less than a kilometer from the water. In East Asian geomancy, a major river is a primary water artery, and a structure placed near a river course is read as a site of water gathering (thủy tụ). A traditional geomancer would further ask whether the river curves to embrace the site or runs straight past it, since a curving embrace retains qi while a straight channel sweeps it away. Lacking a detailed historical hydrological survey of the ancient riverbed, the library notes this simply as the question classical geomancy would pose.
For the Cham builders, the river carried a practical ritual meaning. A Hindu temple requires abundant water for daily ablutions, and a major river nearby provided ready water for bathing the sacred emblem. The priority was ritual water, not geomantic qi.
Regarding the western wall altar niche, traditional Vietnamese architecture places the main altar in the central bay with its back against the rear wall, facing the front door. The niche at Thủ Thiện occupies the exact same position, backed against the rear wall and facing the eastern entrance. Yet this is a coincidence of layout rather than a shared doctrine. Vietnamese builders align the altar with the axis of the house, whereas Cham builders aligned the sacred object with the path of the morning sun. The library sets the two rationales side by side without using one to explain the other.
VThe inner chamber and ancient worship
Thủ Thiện Tower is now an inactive monument where Cham religious rites are no longer performed, and no source records any ongoing ceremonies here. Because the principal deity remains unconfirmed, the library does not reconstruct a hypothetical festival calendar. Instead, the table below follows each architectural element of the chamber, noting its ritual role in a Cham kalan and what remains visible at Thủ Thiện today.
| Part of the tower | Ritual role in a kalan | What remains at Thủ Thiện |
|---|---|---|
| Eastern doorway | The sole entrance, admitting early morning sunlight onto the sacred emblem | The arch once partially collapsed and has been restored |
| Three false doors | Maintain four-sided symmetry without serving as passages | Relatively intact with multi-layered spearhead arches |
| Inner chamber | Compact sanctum for the sacred emblem and officiating priest | No in-situ statue or pedestal remains, though a sandstone Nandin bull statue was found nearby |
| Wall mounting sockets | Slots for attaching relief plaques or subsidiary icons | Numerous sockets remain, while the reliefs are gone |
| Western wall altar niche | Recessed housing on the axis of the eastern door, exact icon unknown | Intact pointed-arch niche, unique among Cham towers |
Today the Katê festival of the Bàlamôn Cham is celebrated only at active sanctuaries in the former Ninh Thuận and Bình Thuận provinces, such as Po Klong Garai Tower, where visitors can still witness a kalan being opened, the sacred emblem bathed, and ceremonial vestments draped over the deity. Projecting that living rite into the dim chamber of Thủ Thiện helps one picture how the pointed-arch niche on the western wall once stood amid candlelight and aloeswood smoke.

Because the tower is small and its inner chamber is narrow and dark, visitors are expected to enter one or a few at a time, move slowly, and avoid blocking the eastern doorway. Visitors should not touch the altar niche on the western wall or the relief sockets, use bright flash photography close to the brickwork, or wedge incense sticks into wall crevices. As the roof and wall surfaces have recently undergone conservation, climbing onto the base platform is not permitted.
