Angkor • Cambodia: Preah Khan temple - Khmer Architectural Gem

Preah Khan is a religious complex northeast of Angkor Thom, within the Angkor site in Cambodia. Its name means “sacred sword”. Associated with Buddhism, it also contains shrines dedicated to Hindu deities. The complex brings together courtyards, galleries, passageways and several enclosures surrounded by a moat. Its buildings survive in varying conditions, ranging from partially preserved structures to collapsed remains. Visitors follow a succession of worship spaces and associated buildings, with carved decoration visible throughout the complex. Conservation work at Preah Khan focuses on stabilising the surviving structures and preserving their sculptural elements while maintaining access to the site.

Preah Khan: Royal Foundation and Religious Change at Angkor

Foundation and Dynastic Commemoration

Preah Khan, northeast of Angkor Thom, was established under Jayavarman VII. The consecration of its principal image is conventionally dated to 1191, ten years after the king’s accession. This date identifies a documented religious ceremony rather than necessarily marking the completion of every building. The foundation encompassed a sanctuary, monastic accommodation, service areas and an extensive system of support beyond the surviving temple enclosures.

The king dedicated the foundation to his father, Dharanindravarman II. In the central sanctuary, the deceased ruler was represented through an image of Lokeshvara, the Buddhist figure associated with compassion, consecrated under the name Jayavarmesvara. This identification placed the king’s ancestry within the temple’s religious programme. Worship at the foundation consequently combined Buddhist devotion with the commemoration of a royal parent and the affirmation of dynastic legitimacy.

The original Sanskrit designation, Nagara Jayasri, referred to a city of glorious victory. The foundation commemorated Jayavarman VII’s defeat of the Chams and was presented as occupying the location of a decisive confrontation. The modern name, Preah Khan, means “sacred sword”. These associations connected the sanctuary’s dedication to the king’s father with the celebration of military victory, although the commemorative narrative does not independently establish the precise geography of the battle.

Religious Community and Economic Organisation

The foundation stele, catalogued as K. 908, provides the principal evidence for Preah Khan’s early organisation. Its Sanskrit inscription comprises 179 stanzas and identifies Prince Virakumara, a son of Jayavarman VII, as its author. Invocations, royal genealogy, dedications and inventories appear together in the text. Its account therefore combines praise of the ruler with detailed statements about the resources assigned to sustain worship.

The inscription records sacred images, precious objects, provisions and categories of personnel. It also describes contributions from villages and supplies issued through royal storehouses. These arrangements demonstrate that the sanctuary depended on an extensive network of production and redistribution. Its activities required agricultural resources and specialised labour as well as religious personnel. The surviving stone buildings represent only part of the institution described by the inscription.

The large numerical totals associated with Preah Khan require careful interpretation. They refer to different groups and obligations, including people attached to supporting settlements, rather than necessarily counting residents within the outer enclosure. Treating every dependent as an inhabitant of the temple would exaggerate what the inscription establishes. Its figures illuminate the scale claimed for the foundation’s resources, while leaving questions about practical administration and the frequency of particular services.

Preah Khan also supported religious learning and is frequently described as a Buddhist university. That modern designation summarises its monastic and educational functions; it does not establish an institution organised like a contemporary university. Hindu deities were included alongside Buddhist images in its original religious programme. Their presence therefore cannot be explained solely as the result of later religious alterations. The foundation accommodated several forms of worship within a predominantly Buddhist royal dedication.

Religious Alterations and Later Use

Buddhist images at Preah Khan were subsequently defaced or recut. These interventions changed the sanctuary’s sculptural programme without systematically demolishing its buildings. Their selective character distinguishes them from damage caused by collapsing masonry, weathering or the removal of portable statues. The surviving surfaces preserve evidence of deliberate interference with particular representations, although not every damaged image can be assigned to the same episode.

Such alterations have traditionally been associated with the reaction against Buddhism attributed to Jayavarman VIII during the later thirteenth century. However, the attribution of all this damage to his personal orders remains uncertain. Neither a single date nor a uniform campaign can be established for every intervention at Preah Khan. The material evidence demonstrates changes in the treatment of Buddhist imagery more securely than it identifies the individuals responsible.

The subsequent history of the community is less fully documented than its foundation. No securely established date marks the abandonment of the entire complex. The disappearance of buildings made from perishable materials has particularly reduced the evidence for residential and service areas. Consequently, the present concentration of stone galleries, shrines and courtyards gives an incomplete picture of the institution’s earlier operation. The ruined condition of the temple should not be attributed automatically to one destructive event.

Contemporary Developments Elsewhere

The conventional consecration date of 1191 falls during the Third Crusade, when crusading forces captured Acre. In Japan, Minamoto no Yoritomo received the title of shogun in 1192. In northern India, Muhammad of Ghor defeated Prithviraja III at the second Battle of Tarain that same year.

Archaeological Investigation and Conservation

Clearance by the French School of Asian Studies, particularly between 1927 and 1932, progressively reopened the temple’s passages and exposed its buildings. On 13 November 1939, Maurice Glaize discovered the foundation stele beneath fallen masonry in the first eastern gateway. Its recovery substantially expanded knowledge of the consecration, dedications and administration. The inscription supplied evidence that the architectural remains alone could not provide, especially concerning personnel, offerings and the foundation’s external support.

Following the interruption of conservation during Cambodia’s conflicts, the World Monuments Fund began a programme at Preah Khan in 1991. Work emphasised stabilisation, targeted repairs and training for Cambodian conservation professionals. Rather than reconstructing the entire complex, the programme retained substantial areas as partial ruins while addressing threatened structures.

Preah Khan is protected within the serial property officially named “Angkor”, inscribed on the UNESCO World Heritage List in 1992. The APSARA National Authority manages its preservation with specialist partners. Conservation addresses unstable masonry, damaged sculpture and visitor circulation, allowing access while limiting further deterioration of the surviving buildings.

Preah Khan: Enclosures, Galleries and Sanctuary Layout

Setting and Overall Composition

Preah Khan occupies ground northeast of Angkor Thom, immediately west of the Jayatataka reservoir. Its composition extends horizontally through four successive enclosures, without a dominant pyramidal platform. An east–west axis provides the principal line of approach, intersected by a north–south axis at the central sanctuary. Gateways, passages and courtyards follow these directions, while subsidiary buildings create lateral routes. The resulting plan combines strong axial organisation with an increasingly dense arrangement of connected spaces towards the interior, where individual shrines and galleries restrict long views across the complex.

The outer laterite enclosure measures approximately 800 by 700 metres and is surrounded by a moat. Its boundary contains considerably more ground than the densely built religious nucleus. Between the perimeter and the inner enclosures, broad areas now retain relatively few standing buildings. This difference distinguishes the extent of the entire establishment from the concentration of its surviving stone shrines. Residential and service structures made from perishable materials have largely disappeared, leaving an architectural record weighted towards the masonry buildings and their connecting circulation spaces.

Causeways cross the moat on the cardinal approaches, with sculpted figures carrying serpent balustrades, or nagas. Rows of carved stone posts further define sections of the eastern and western routes. The eastern approach develops into a cruciform terrace before the gateway of the religious nucleus. Beyond the outer enclosure, the same axis continues towards a landing platform beside the reservoir. The sequence connects water access, processional approach and enclosed buildings through distinct architectural stages, rather than admitting visitors directly from the moat into the sanctuary precinct.

Gateways, Inner Enclosures and Central Sanctuary

Monumental gateways, or gopuras, articulate the transitions between enclosures. Their central passages, lateral wings and towers distinguish them from adjoining walls and galleries. The eastern entrance to the third enclosure has three passages, with the middle opening larger than those flanking it. Entrances on the other cardinal sides are less extensive. Pediments, lintels and guardian figures concentrate decoration around these crossings. Successive doorframes establish axial views, although changes in floor level and the differing dimensions of openings prevent the route from reading as one uninterrupted interior.

Within the inner enclosures, galleries connect chapels, vestibules and courtyards of varying dimensions. Their junctions create side passages and partially separated groups of buildings. Covered corridors alternate with open courts, producing pronounced changes in light and spatial enclosure. Subsidiary religious complexes retain their own arrangements of shrines and connecting galleries within this wider network. The close spacing of structures makes their relationships easier to understand through plans and successive viewpoints than through a single overview from ground level, particularly where fallen masonry interrupts the original routes.

The central sanctuary occupies the intersection of the principal axes. Its cruciform arrangement combines a central chamber with four projecting vestibules beneath a tower. Closely surrounding buildings restrict the open space around it, so the sanctuary is approached through passages rather than across an expansive forecourt. Structures conventionally called libraries complete parts of the inner arrangement. That designation identifies a recognised architectural category, but does not independently establish the precise use of every surviving chamber or the contents it originally accommodated within the temple’s changing layout.

Hall of Dancers, Two-storey Pavilion and Sculpture

The Hall of Dancers occupies the eastern part of the religious nucleus. Intersecting passages and small courtyards are bordered by galleries and pillared side aisles. Carved friezes of celestial dancers, or apsaras, above the openings explain its modern name. Its plan therefore comprises interconnected covered and uncovered spaces rather than one unobstructed hall. Surviving sections of half-vaulting retain carefully dressed stonework, including ceiling decoration arranged as lotus motifs within recessed compartments. Missing roofs now expose portions of the arrangement that originally functioned as sheltered passages.

North of the hall stands a two-storey pavilion distinguished by substantial, closely spaced cylindrical columns. These supported an upper masonry level, whose surviving window components help establish its former existence. No surviving access stair securely explains the original vertical circulation. Proposed functions, including grain storage or accommodation for a sacred object, remain hypotheses. Opposite the pavilion is a long raised terrace retained by laterite walls. Together, these structures form a distinctive lateral group whose construction is clearer than its original practical or ceremonial use.

Sculpture is concentrated on gateways, pediments, lintels and the outer enclosure. Large Garuda figures grasping nagas punctuate the perimeter wall, while interior scenes include Vishnu reclining on Ananta and other Hindu subjects. Deliberately removed or recut Buddhist images have left surfaces that differ from adjacent carving. These alterations must be distinguished from fractures caused by falling blocks and surface deterioration. Their architectural significance lies partly in the survival of frames and surrounding ornament, which can preserve the placement of an image after its central figure has disappeared.

Masonry, Building Phases and Structural Conservation

Laterite predominates in enclosure walls and some retaining structures, while sandstone forms much of the religious architecture, doorframes and sculpture. Surviving roofs employ variations of corbelling, with successive stone courses projecting inward until the opening can be closed. Narrow galleries accommodate this construction, but junctions with porches, side aisles and towers create more complicated assemblies. Collapsed sections expose the arrangement of blocks behind finished surfaces. They also reveal how the apparent continuity of a gallery depended on several adjoining structural elements remaining aligned and adequately supported.

The complex incorporates multiple building campaigns and alterations. Masonry junctions, differences in construction and analysis of sandstone have helped distinguish stages within the apparently continuous plan. The Hall of Dancers belongs to the development of the eastern sector rather than necessarily reproducing its earliest arrangement. Shared alignment therefore does not establish simultaneous construction: a gateway, gallery and adjacent chamber may follow the same axis while belonging to different phases. Later connections can obscure earlier external walls and turn formerly separate buildings into linked interior spaces.

Conservation has emphasised stabilisation rather than complete reconstruction. In the Hall of Dancers, monolithic sandstone pillars developed longitudinal fractures that threatened their load-bearing capacity. Repairs involved temporarily relieving the weight above, drawing fractured sections together and securing them. Other interventions address displaced lintels, unstable gateways and separated masonry. Roots in contact with buildings require individual assessment because both continued growth and removal can disturb the existing balance of stones. The treatment of each structure consequently depends on its particular supports, fractures and surviving connections.
