India and Indonesia Join Hands to Restore Prambanan Temple, Reviving a Shared Civilisational Heritage

India and Indonesia have taken a significant step towards preserving their centuries-old cultural and civilisational links with the launch of a joint conservation and restoration project at the historic Prambanan Temple Complex in Yogyakarta. The initiative brings the expertise of India’s Archaeological Survey of India (ASI) together with Indonesia’s heritage authorities to protect one of Southeast Asia’s most remarkable Hindu monuments.

Prime Minister Narendra Modi and Indonesian President Prabowo Subianto jointly marked the beginning of the project during Modiji’s visit to Prambanan on July 8, 2026. The two leaders unveiled a commemorative plaque at the UNESCO World Heritage Site, formally signalling the commencement of the ASI-led conservation effort. The initiative follows an understanding reached during President Prabowo’s state visit to India in 2025 regarding India’s assistance in the restoration of the temple complex.

The partnership is significant not only because of the scale of the conservation work but also because Prambanan represents a visible reminder of the historic cultural exchanges between the Indian subcontinent and the Indonesian archipelago.

Prambanan: A Monument to Hindu Architecture in Indonesia

Prambanan is one of Indonesia’s most extraordinary archaeological sites and one of the most important surviving examples of Hindu architecture in Southeast Asia. The main complex, also known as Loro Jonggrang, dates to the ninth century and is dedicated to the Hindu Trimurti—Shiva, Vishnu and Brahma.

The towering temples are decorated with intricate stone reliefs depicting episodes from the Ramayana, demonstrating how Indian religious traditions and epic literature became deeply integrated into the cultural landscape of ancient Java. UNESCO recognises the complex for its exceptional architectural and artistic value and notes that the wider archaeological area contains more than 500 temples and shrines.

The Prambanan Temple Compounds were inscribed on the UNESCO World Heritage List in 1991. The site includes not only the Hindu Prambanan complex but also the Buddhist Sewu, Bubrah and Lumbung temple groups. This remarkable coexistence of Hindu and Buddhist monuments provides evidence of the religious and cultural diversity of ancient Java.

Restoring the Forgotten Shrines

A major focus of the new conservation programme will be the restoration of the Pervara temples, the smaller subsidiary shrines surrounding the principal temples. The complex originally contained 224 such shrines arranged in four concentric rows. According to official information reported by The Indian Express, only six of these have been restored so far, leaving 218 in various stages of ruin.

The restoration will therefore go beyond preserving the already prominent central temples. It will seek to recover and conserve parts of the wider architectural landscape, giving greater attention to structures that have remained in ruins for centuries.

This makes the initiative particularly important from an archaeological perspective. Rather than treating restoration simply as rebuilding, specialists will have to determine the original location and purpose of surviving stones and architectural fragments before attempting their reassembly.

A Decade-Long Scientific Conservation Mission

The project is planned to run for ten years, from 2026 to 2036, with an estimated outlay of ₹65 crore. The ASI will undertake the work in collaboration with the Indonesian Heritage Agency.

Modern technology will play a major role in the conservation process. The project is expected to use LiDAR-based surveys and photogrammetric documentation to record scattered stone elements and create detailed digital information about the structures. Archaeological research will be supported by structural, hydrological and geotechnical studies.

Such scientific documentation can help conservation experts understand the condition of the monument, identify surviving original components and determine how different architectural elements were arranged. It can also create a detailed digital record that may prove valuable for future research and preservation efforts.

A Monument That Has Survived Earthquakes and Volcanic Activity

The restoration of Prambanan is particularly challenging because the complex has endured centuries of natural and historical changes. UNESCO records that the temples suffered destruction and collapse associated with earthquakes, volcanic eruptions and changes in political power during the early 11th century. Restoration efforts at the site have been taking place since the early 20th century.

The wider Prambanan region remains vulnerable to natural hazards, particularly earthquakes and volcanic activity. This makes scientific conservation and structural monitoring essential for protecting the monument over the long term. The new project can therefore build upon decades of earlier conservation efforts while introducing more extensive documentation and modern technical methods.

India’s Growing Role in Heritage Conservation

The collaboration also highlights the international experience of the Archaeological Survey of India. India has developed considerable expertise in the conservation, documentation and management of historic monuments, and has previously undertaken extensive documentation work at Indonesia’s Borobudur Temple Compounds.

The Indian government has described the Prambanan initiative as part of its broader commitment to preserving shared civilisational heritage. By contributing archaeological and conservation expertise outside India, the ASI is also strengthening technical cooperation with another major Asian country.

The partnership demonstrates how archaeological expertise can become an important component of cultural diplomacy. Instead of heritage remaining confined within national boundaries, countries with historical connections can work together to protect monuments that reflect their intertwined histories.

India and Indonesia’s Shared Cultural Connections

The importance of Prambanan extends far beyond its stone architecture. The monument stands as evidence of the movement of ideas, religious traditions, artistic practices and literature between India and Southeast Asia over many centuries.

The presence of the Ramayana in the temple’s reliefs is particularly significant. An Indian epic has been preserved not only in religious and literary traditions but also in the architecture and artistic heritage of Java. The story has subsequently remained an important part of Indonesian cultural expression.

Prambanan and the nearby Buddhist temple complexes also demonstrate that ancient Java was a place where different religious traditions existed alongside one another. UNESCO describes the wider complex as evidence of the peaceful coexistence of Hindu and Buddhist religious traditions in the region.

Heritage as a Bridge Between Two Nations

The restoration initiative gives India and Indonesia an opportunity to translate their historical connections into practical cultural cooperation. While the two countries have developed modern diplomatic, economic and strategic relationships, their cultural links provide a much older foundation for bilateral engagement.

The joint preservation of Prambanan reinforces this connection in a particularly meaningful way. India is contributing its archaeological expertise while Indonesia remains the custodian of the monument and its surrounding heritage landscape.

The project also reflects a broader understanding that cultural heritage can strengthen relations between nations. Preserving an ancient monument together creates opportunities for archaeologists, historians, engineers and conservation specialists from both countries to work closely with one another.

Protecting a Legacy for Future Generations

The restoration of Prambanan is ultimately about ensuring that future generations can experience and study a monument that has survived for more than a millennium. Its importance lies not only in its religious associations but also in what it tells us about the architectural sophistication, artistic achievements and cultural exchanges of ancient Southeast Asia.

The use of modern surveying and documentation techniques alongside established conservation practices can help ensure that restoration remains grounded in archaeological evidence. At the same time, careful preservation of original materials will be essential to maintaining the authenticity that makes Prambanan a globally significant heritage site.

The MGMM Outlook 

India and Indonesia’s joint effort to conserve the historic Prambanan Temple is more than a heritage project; it is a meaningful reflection of the deep civilisational connections that have linked the two countries for centuries. The participation of the Archaeological Survey of India alongside Indonesian heritage authorities brings together expertise and shared cultural history to protect one of Southeast Asia’s most important Hindu monuments. The restoration of the temple’s numerous subsidiary shrines, supported by modern technologies such as LiDAR and photogrammetry, can help preserve Prambanan’s architectural legacy while ensuring that its historical authenticity is carefully maintained.

Prambanan also reminds us that India’s cultural influence travelled far beyond geographical boundaries through ideas, literature, spirituality and artistic traditions. The temple’s Ramayana reliefs and its association with the Hindu Trimurti stand as enduring evidence of these historical exchanges, while the presence of nearby Buddhist monuments reflects the cultural diversity of ancient Java. By contributing its conservation expertise to the restoration, India is helping safeguard a shared Asian heritage while further strengthening its cultural relationship with Indonesia. The project demonstrates how the legacy of the past can become a foundation for meaningful cooperation in the present, ensuring that this remarkable civilisational connection continues to inspire future generations.
