The role of AGI in preserving historical sites

From emergency documentation of earthquake-damaged buildings that reached 88% accuracy to semantic digital twins that encode structured risk memory, artificial intelligence is transforming heritage preservation. The technology enables teams to move faster, document at scale, and anticipate threats—but the interpretive and ethical judgments at the heart of preservation remain distinctly human.
A New Toolkit for an Ancient Mission
The integration of AI into heritage preservation is not about replacing human expertise—it is about augmenting it. As the 2026 Historic Preservation Symposium at Texas A&M University concluded, AI works best when teams use it for specific tasks. It can help collect and analyse large amounts of information, but the interpretive and ethical judgments at the heart of preservation work remain distinctly human.
The urgency is clear. Europe's Chief Scientist for Research, Innovation and Technology has framed digital cultural heritage as "strategic infrastructure" and "part of Europe's knowledge sovereignty". If Europe's monuments, languages, rituals, and archaeological evidence are not digitised and made available in trusted formats, future AI systems may interpret the past through incomplete or distorted sources.
From Emergency Response to Long-Term Stewardship
Disaster Documentation. After the 2020 Beirut port explosion, teams documented 240 heritage buildings using photogrammetry—a technique that creates 3D models from overlapping photos. Those models helped stabilise 60 high-risk buildings within one month. As UNESCO specialist Dr. Joe Kallas noted: "Too often, historic buildings are lost—not because they are beyond repair, but because we didn't have the time or the right information at the right time".
A machine learning framework trained on post-disaster imagery now identifies multiple damage types on unreinforced masonry with 88% accuracy when tested on photos it had not seen before.
Large-Scale Monitoring. At Pompeii, which has 1,221 buildings across 44 hectares and can receive up to 20,000 visitors per day, teams use satellite analysis to track ground movement and drone surveys to document roofs and drainage. A full-site survey completed in 2025 produced more than 70,000 inspection records. The site is also testing a four-legged robot that repeats inspection routes and a project using AI and robotics to reconstruct shattered frescoes from stored fragments.
Finding the Undocumented. The Preserve AI project, launched after the 2023 Kahramanmaras earthquakes in Turkey, uses GIS mapping tools and machine learning to flag buildings that appear consistently across decades of aerial photographs. It helps teams identify potentially historic structures when on-site access is limited. As Dr. Bilge Kose put it: "AI is not a replacement for preservationists. It is a scout that scales our eyes. It processes the haystack to find the needles, the heritage sites waiting for our professional attention".
The Memory Twin: From Digital Copy to Contextual Understanding
The concept of a "memory twin" extends the idea of a digital twin. A digital twin captures form; a memory twin captures context. A digital twin shows what exists; a memory twin helps explain what it means.
The integration of the ICCROM/CCI ABC method for risk assessment into semantic digital twins enables the structured encoding of risk cognition over time. This structured risk memory becomes the foundation for agentic reasoning, supporting prioritisation, justification, and long-term preservation planning. Proof-of-concept simulations illustrate how memory-enabled agents can trace evolving risk patterns, trigger policy responses, and evaluate mitigation outcomes through structured, explainable reasoning.
The Narratia project is taking this further, combining generative AI and mixed reality to transform heritage sites into dynamic narrative ecosystems where visitors become protagonists. Cultural and historical landmarks turn into immersive stages, enabling visitors to interact with historical characters and experience history first-hand.
The Limits: What AI Cannot Do
Despite the promise, preservation experts are clear about AI's limitations. Field experience still matters because many preservation decisions happen at the building surface, where skilled observation guides what comes next.
Robert Kornfeld, a historic preservation specialist, illustrated the limits with a project at the New York Central Building, where physical probing revealed severely corroded internal steel concealed behind terracotta columns. AI could not diagnose the cause; a professional identified the risk through hands-on investigation and interpretation of crack patterns.
As Philip Chen of Annum Architects argued: "Human intelligence, at least now, is still important when it comes to processing meaning, processing values, processing morality".
A Shared Horizon
For Global Future Nexus, the role of AGI in preserving historical sites is central to the mission of planetary sustainability and borderless human potential. The question is no longer whether AGI can help preserve heritage—it already is. The question is whether we will build the governance frameworks to ensure that this preservation is scientifically validated, respectful of cultural authenticity, and aligned with human flourishing.
