Restoration of the Dancing Shiva: A 10th-Century Khmer Masterpiece Rebor

After fifteen years of painstaking Franco-Cambodian work, the dancing Shiva, a unique 10th-century masterpiece, has been reborn from its thousands of fragments. A ceremony celebrated its completion on March 18, 2026, in Siem Reap.

There are images that seem to condense more history than others. They are not always the most famous, nor necessarily those that, indifferent to human turmoil and fury, cross the centuries unscathed. They are often those whose very scars bear witness to the heavy toll paid to the upheavals of history. The monumental statue of the dancing Shiva from Prasat Thom – the grand 10th-century temple built at the heart of Koh Ker, the ancient rival city of Angkor – is one such exceptional image. Undoubtedly a unique and emblematic masterpiece of Angkorian history.

On March 18, 2026, at the Angkor Conservation Office in Siem Reap, a ceremony presided over by Her Excellency Dr. Phoeurng Sackona, Minister of Culture and Fine Arts of the Kingdom of Cambodia, and under the authority of His Excellency Mr. Kong Puthikar, Director General of the National Authority for Preah Vihear (NAPV), marked the culmination of this extraordinary Franco-Cambodian project.

A Sandstone Colossus

The monumental statue of the dancing Shiva was erected during the first half of the 10th century in the grand royal temple of Prasat Thom, founded by King Jayavarman IV at Koh Ker – an ephemeral capital of the Khmer kingdom that, for two decades, eclipsed Angkor, located eighty kilometers away.

The god's image is carved from a single block, originally nearly five meters tall. Most likely, the statue was erected before the construction of the tower that houses it today. The god himself, with flexed legs, measured 3.60 meters in height and nearly 3 meters in width. The total weight of the statue can be estimated at between seven and nine tons. It is not only the colossal proportions of the sculpture that impress, but also the remarkable technical and artistic feat that made its execution possible. There is no real equivalent in ancient Cambodia to an image carved from a single block of such magnitude while conveying a posture as dynamic as Shiva's victorious dance.

Like a Theater Scene

The sculpture did not stand as an isolated image, but was part of a sculpted group in which the different "actors," like on a theater stage, participated in the god's dance. Shiva was thus surrounded by four other life-sized divinities. They were arranged according to two combined principles: the goddesses precede the male guardian divinities; the peaceful forms are placed to the god's right, while the terrifying forms stand to his left.

Thus are represented Shiva's two consorts, Uma and Kâlî-Câmundâ. The beautiful and smiling Uma (to the god's right), also depicted in a dancing posture, is currently kept at the Guimet Museum in Paris. Kâlî-Câmundâ, the fierce and bloodthirsty form of the goddess, is shown seated, facing the dancing couple, holding the remains of a dismembered body. She is now on display at the National Museum of Cambodia in Phnom Penh.

Slightly set back, and having suffered significant damage due to looting, are the two "commanders of Shiva's troops," Mahâkâla and Nandikeśvara. The first, with bulging eyes and prominent fangs, displays the same fierce features as Kâlî-Câmundâ, while the second joyfully plays the drum to the rhythm of the divine dance. On each side of the god are thus evoked two complementary aspects of Shiva's dance – or more precisely, two distinct moments: that of destruction (of the forces of chaos and enemies of cosmic order), corresponding to the projection of the goddess's martial forces; and that of victory and restored harmony, embodied in the union of the god and goddess, whose pas de deux is ultimately an euphemism.

An Unparalleled Iconography

Although it is not the oldest image of a dancing Shiva in ancient Cambodia, it is the first – and, in many respects, the only – to combine such highly specific iconographic features, even when expanding the comparison to the Indian subcontinent, the birthplace of Shiva's dance.

In the profusion of artistic productions from Indian and Indianized kingdoms, there is nowhere else this original and hybrid form of a ten-armed Shiva who is both dancing and endowed with five heads. Representations of Shiva's dance are numerous, sometimes with ten arms; representations of a five-headed god are not rare either. However, these two forms are never combined into a single image.

A Palladium Image of the Khmer Kingdom

For the historian, this singularity must be understood in light of the central role this sculpted ensemble played in the religious and political history of Cambodia. It establishes, for the following centuries, the iconographic formula by which the god manifests and becomes visible on earth as the "Lord of Worlds," that is, as the tutelary divinity of human action and, above all, of the king.

The same dance is reproduced in bas-relief on the pediments of temples at the kingdom's main sacred sites, notably Banteay Srei, Preah Vihear, and Vat Phu. This image probably remained a palladium of ancient Cambodia – a protective and symbolic image of the kingdom – until the statue was toppled, probably in the 14th or 15th century, during the fire of the tower, as documented by archaeological excavations conducted in 2012.

The Making of a Neak Ta: A Territorial Guardian Spirit

Once fallen, over the centuries, the pedestal and fragments of the statue became, in the new proximity of wooden Buddha images, associated with a Neak Ta cult – one of those territorial spirits that, in some respects, are heirs to earlier cults.

The Neak Ta of Prasat Kraham remains particularly renowned for its power to this day. Transporting the fragments collected from the site in 2012 and 2013 to Siem Reap required informing this spirit and seeking its permission. Through a medium – herself a dancer – the Neak Ta expressed the wish that the statue, once restored, return to Koh Ker, which is indeed the current plan.

Modern-Era Dispersion

In modern times, the Uma statue was already noted at the end of the 19th century during expeditions organized by Louis Delaporte, who decided to send it to Paris (but without its feet or pedestal). However, it was in the 1920s and 1930s, thanks to Henri Parmentier's work, that the sculpted group was photographed and properly documented for the first time. A foot and several hands of Shiva, as well as the torso of the goddess Kâlî, then entered the collections of the Phnom Penh museum.

During the troubled years preceding independence, and up to 1960, the museum curator Jean Boisselier again decided to transfer to Phnom Penh several remarkable pieces of Koh Ker statuary that had remained in situ. It was on this occasion that Shiva's summit head and one of the four lower faces were safeguarded.

Looting

Until the late 1960s, the site and its sculptures remained relatively preserved. But in the following decades – particularly before and after the Khmer Rouge came to power, and up to the mid-1990s – Koh Ker became the target of systematic and highly organized looting, the true extent of which could only be assessed in the last decade.

At Prasat Thom, looters chiseled Shiva's torso to detach the three heads left by Jean Boisselier. The pedestal tenons, as well as the statues of Mahâkâla and Nandikeśvara, underwent the same treatment. Like other Koh Ker sculptures, these pieces followed antiquities trafficking routes to end up in private collections – European, Asian, and especially American – or, in some cases, in public collections, such as one of the pedestal lions now kept at the Dallas Museum of Art.

2012: Launch of an EFEO Archaeological Mission at Koh Ker

It was in 2012 that the story took another turn. Under the impetus of Éric Bourdonneau, lecturer at the French School of the Far East (EFEO) and head of the archaeological mission at Koh Ker, and in close collaboration with the National Authority for Preah Vihear (NAPV), a systematic excavation was undertaken inside Prasat Kraham.

More than 10,000 fragments were collected, including several thousand bearing sculpted surfaces belonging to the dancing Shiva and the four accompanying divinities. About 2,750 fragments corresponding to sculpted surfaces were precisely inventoried and are the subject of a database containing 5,860 photographs.

Traces of polychromy were observed on Shiva's body and sampot (loincloth). Examined under a microscope by Esther von Plehwe-Leisen of the German Apsara Conservation Project (GACP), they reveal complex layers. Geochemist Christian Fischer identifies lead, mercury, and cinnabar in the pigments.

Preparing the Fragments: Securing, Documenting, Classifying (2012-2018)

Except for the large pedestals of Shiva and Mahâkâla, which remained in situ, all fragments were transferred to the Preah Norodom Sihanouk Museum in Siem Reap in 2012-2013, thus removing them from the permanent risks of theft or deterioration.

From 2013 onward, a major documentation and conservation campaign was undertaken. Stabilization and consolidation treatments were carried out in parallel. The GACP intervened on Shiva's multi-headed nâga pedestal. Minimal cleaning was performed on about 150 pieces. The restoration workshop of the National Museum of Cambodia also cleaned blocks and the pedestal left in situ.

Two 3D Scanning Campaigns (2011-2013 / 2022)

Initial 3D scanning campaigns were conducted in 2011 and 2013, in partnership with Heidelberg University, including the scanning of 13 fragments kept at the National Museum of Cambodia in Phnom Penh and 62 fragments discovered during the Koh Ker excavations. These first scans allowed visualization of this three-dimensional "puzzle" and evaluation of hypotheses before undertaking large-scale test assemblies requiring heavy lifting equipment.

The scanning was then completely redone and supplemented by the project team in 2020, producing a more complete and precise set of data integrating verified connections between fragments.

Technical Study: From Virtual Model to Physical Reassembly (2018-2019)

In 2018, a preliminary mission was entrusted to sculptor restorer Benoit Lafay, and in 2019, a dedicated workshop was set up at the Angkor Conservation Office in Siem Reap to carry out the technical study prior to restoration.

This phase focused on three objectives: test assembly of the largest blocks; systematic search for joins between fragments among thousands of pieces; and temporary and reversible assembly of selected elements to facilitate handling and study.

The central question concerned the proportion of the torso surface that could realistically be reassembled after the 1990s looting. After eight months of daily work, significant results were obtained. Among the identifiable sculpted surface fragments, 575 showed at least one confirmed joint. Nearly 100 additional fragments without sculpted surfaces were reintegrated into the internal core of the torso, contributing to restoring its volume. In total, between 70% and 75% of the torso surface can be repositioned, allowing the formal continuity of the sculpture to be restored.

The perspective of the project changed fundamentally. What seemed almost impossible became technically feasible. Emphasis then shifted to structural stability, reinforcement of main fragments, technical solutions, and ethical choices regarding the level of intervention.

The Restoration Committee: A Collegial Framework (2019)

Given the scale and complexity of the project, a scientific and technical committee was formed. Meeting in December 2019, it validated the principle of restoration, subject to additional structural studies. Throughout the process, the committee reviewed reassembly technical choices, the extent of restitution, and the aesthetic reintegration approach. The goal remained to restore the legibility and monumentality of a unique sculpture while ensuring that the material traces of its history remain perceptible.

Designing the Support Strategy

As reassembly progressed, it became clear that restoring volumes was only part of the challenge. The central question was to ensure long-term stability of the main blocks – particularly the arms and legs – given internal cracks and structural stresses associated with drilling and loading needed for assembly.

Ultrasound tests conducted by the GACP in 2020 and 2022 identified the extent and location of internal weaknesses, which proved decisive for defining the support strategy. Two options were examined: an external support frame acting as a structural back, or an internal system organized around a central mast with branched supports penetrating the sculpture.

While an external structure would have transferred the load to a peripheral chassis, it would also have introduced a heavy and visually intrusive support, compromising the perception of the sculpture in the round – essential for a five-headed dancing Shiva. The internal system was therefore developed with rigorous guarantees, including detailed mechanical calculations and controlled load distribution, as well as consolidation of the most fragile fragments. This solution secures the statue while preserving its legibility, monumentality, and spatial presence.

Consolidate Before Assembling

Once the structural option was defined, the most fragile fragments were consolidated to stabilize cracks and restore stone cohesion before assembly, ensuring the fragments could safely support their own weight.

In parallel, the main elements were prepared for mounting on the internal structure. Precise drilling allows insertion of stainless steel supports, while laser guidance ensures precise three-dimensional positioning. This step requires millimeter precision to guarantee correct alignment and long-term stability.

Building the Internal Structure

The support system is designed as an internal metal structure capable of bearing the total weight of the sculpture – estimated at over seven tons – while remaining largely invisible inside the statue. A square steel base evenly distributes the load, from which rises a vertical mast placed at the sculpture's center of gravity. Carefully dimensioned, this mast replaces the missing sculpted fabric fall of the sampot between the legs, assuming its former structural role.

The torso core rests on a custom-shaped steel cradle, topped by a metal "capital" that anchors the shoulder and arm blocks and stabilizes the upper structure. Additional independent supports are introduced for each leg, ensuring the weight is safely transferred to the structure rather than borne by the stone itself. As reassembly progressed, precise measurements revealed a slight asymmetry between the two flexed legs, confirming a more dynamic pose than previously assumed.

Reintegrating Missing Parts

The project then turned to defining how missing parts should be completed. Rather than applying a single global solution, the team adopted a series of precise, case-by-case decisions.

Restoration – understood here as the restitution of lost parts – is undertaken only when supported by material evidence (preserved fragments, significant break lines, structural logic) and in-depth knowledge of Koh Ker statuary. At the same time, particular attention is paid to maintaining a consistent level of intervention across the entire sculpture. The goal is to recover formal coherence and legibility while ensuring added areas remain distinguishable from original material upon close examination.

These principles lead to several concrete decisions. The treatment of the sampot reflects this approach. The internal mast now assumes the structural role once played by the sculpted fall between the legs. As no fragment of this element survives, its sculpted decoration was not recreated; the mast is simply clad for visual integration.

In contrast, the lower legs and feet proved essential to the statue's balance, dynamism, and proportions. Their reintegration was supported by preserved fragments, clearly readable break lines, and strong formal parallels within the Koh Ker corpus.

The forearms were reintegrated only where original wrists or hands are preserved, allowing authentic hands and attributes to be repositioned. Some attributes were fully restituted when documentation justified it – like the lasso, known from archive photographs – or when preserved fragments allowed coherent reconstruction, as in the case of the mace.

Finally, the three missing lower faces were reproduced from a mold of the preserved original face (right), faithfully following the original arrangement of the statue's multiple faces, documented by pre-looting photographs and identical lower faces on other multi-headed sculptures in the Koh Ker style. This choice ensures coherent reading of the five-headed iconography while maintaining consistency in the overall level of intervention.

Restoration Techniques and Materials

Missing volumes were first reconstituted using lightweight resin shells, designed to limit additional weight on an already fragile structure while providing a stable base for surface treatment. These shells were then covered with restoration mortars composed mainly of sandstone powder mixed with lime.

Particular attention was paid to colorimetric integration. Natural pigments were incorporated into the mortar, and final adjustments were made using fine lime-based patinas applied by brush to achieve subtle tonal harmonization. All additions remain identifiable upon close examination by a slight surface differentiation, while preserving the overall unity and legibility of the sculpture.

An Exemplary Cooperation Project

The project is conducted under the high patronage of Her Excellency Dr. Phoeurng Sackona, Minister of Culture and Fine Arts of the Kingdom of Cambodia, and under the authority of the National Authority for Preah Vihear (NAPV), led by His Excellency Mr. Kong Puthikar. It is directed by the French School of the Far East (EFEO), under the responsibility of Éric Bourdonneau in cooperation with the NAPV.

The restoration team is led by sculptor restorer Benoit Lafay, in close collaboration with Mr. Chhan Chamroeum, Deputy Director of the Angkor Conservation Office and head of its restoration team. Many international experts contributed to the project, notably the German Apsara Conservation Project (GACP) led by Professor Hans Leisen.

The project benefited from financial support from the International Alliance for the Protection of Heritage in Conflict Areas (ALIPH), as well as many other partners including the Simone and Cino Del Duca Foundation – Institut de France, GFC Pharma, and the French Embassy in Cambodia.

ALIPH Foundation in Cambodia

ALIPH has been engaged in Cambodia since the adoption of its first project in the country in October 2020. Since then, the Foundation has supported a portfolio of projects reflecting the diversity and richness of Cambodian heritage, ranging from the conservation of monumental sculptures to the restoration of major temples and the safeguarding of important museum collections. These initiatives combine support for national institutions, capacity building for local teams, and transmission of traditional know-how.

To date, ALIPH has committed nearly one million US dollars to support five projects in Cambodia. In addition to the restoration of the dancing Shiva, ALIPH also supports the restoration of Prasat Kraham at Koh Ker, the temple from which the sculpture originates, as well as the restoration of the Western Mebon temple and the reclining Vishnu statue from it.

A New Chapter

On March 18, 2026, Koh Ker's colossus will dance again. Not as it did eleven centuries ago, in the gloom of its sanctuary, but in the rediscovered light of the Angkor Conservation Office, bearer of all the strata of its millennial history. As the press kit so aptly writes: "to welcome into our present time this extraordinary creation of ancient Cambodia – Koh Ker's colossus – and offer it a new space where it can dance again: not exactly as 1,100 years ago, but dance nonetheless."
