Cultural heritage science combines archaeology, materials science, environmental science and digital technologies to study, protect and interpret objects, buildings and sites from the past. Researchers begin by documenting cultural assets in detail, using high resolution photography, 3D scanning, satellite imagery and geographic information systems. This creates precise digital records that can be used to monitor condition, support restoration and enable virtual access when physical visits are limited.

A key focus is understanding how materials age and deteriorate. Scientists investigate how stone, metals, pigments, textiles and paper respond to light, humidity, pollutants, biological growth and temperature changes. Laboratory experiments and long term field monitoring help identify the main decay processes and the environmental thresholds that accelerate damage. This knowledge guides preventive conservation, climate control in museums and the planning of protective structures or restricted access in vulnerable sites.

Another important strand is the development of non invasive analytical techniques, such as X ray fluorescence, infrared imaging and laser based methods, which reveal composition, structure and hidden features without removing samples. These tools can uncover overpainted artworks, construction phases in buildings and manufacturing technologies used by past societies.

Digital humanities and data science play an increasing role. Large datasets from surveys and archives are used to model risks from climate change, natural hazards and urban development, helping set priorities for conservation. At the same time, virtual and augmented reality, online platforms and open databases are expanding public engagement, allowing wider communities to explore and participate in the stewardship of cultural heritage.
