Key Highlights
- India's Archaeological Survey joins forces with Indonesia to conserve the Prambanan UNESCO site.
- The partnership adopts anastylosis, rebuilding structures primarily with original stones.
- Digital mapping and AI will assist in locating and re‑positioning scattered fragments.
- Restoration will extend beyond Prambanan to nearby Sewu and Plaosan temples, preserving the whole cultural landscape.
Detailed Insights
On 16 March 2026, Indonesia’s Culture Minister Fadli Zon welcomed a delegation from the Archaeological Survey of India (ASI) in Jakarta. Both governments agreed to cooperate on a multi‑phase programme that safeguards the 9th‑century Prambanan temple ensemble, a hallmark of Hindu architecture in Southeast Asia. The plan emphasizes a holistic approach: while Prambanan itself receives priority, the adjoining Sewu and Plaosan shrines—symbols of syncretic Hindu‑Buddhist traditions—will also undergo systematic treatment.
The cornerstone of the technical methodology is anastylosis, a scientifically validated process that reconstructs edifices using only those stones originally belonging to the structure, inserting new material solely where structural integrity demands it. ASI experts have catalogued dozens of peripheral ‘perwara’ shrines that will be restored under this protocol. A major logistical hurdle is the dispersion of thousands of ancient blocks across the site, a challenge that will be mitigated through high‑resolution photogrammetry and machine‑learning algorithms capable of matching fragments.
Implementation will commence with a pilot phase targeting one or two auxiliary temples. Outcomes from this trial will inform the scaling‑up of techniques, ensuring that both authenticity and durability are maximised. The collaboration signals a widening trend of cross‑border cultural stewardship, leveraging Indian archaeological know‑how and Indonesian digital innovation.
Key Concepts
- Anastylosis: A reconstruction method that reassembles ruins using original stones, supplementing with new material only when absolutely necessary.
- Perwara temple: A subsidiary shrine that forms part of a larger temple complex, often serving auxiliary religious functions.
- Digital photogrammetry: The use of photographic imagery to generate accurate three‑dimensional models of archaeological sites.
