Founded by ICOMOS in 1996, in service of built heritage.
The International Scientific Committee on the Analysis and Restoration of Structures of Architectural Heritage (Iscarsah) was founded by ICOMOS in 1996 as a forum and network for engineers and architects involved in the restoration and care of building heritage. The first meeting of the Iscarsah took place at the Engineering University in Rome in March of 1997, and the committee has met twice a year since then in venues all over the world.
Members of the Iscarsah are composed of internationally renowned engineers, architects, scientists, specialists, and educators with representation of the five continents.
The Committee has authored the ICOMOS Charter – Principles for the Analysis, Conservation and Structural Restoration of Architectural Heritage (Iscarsah Principles), which were ratified by the ICOMOS 14th General Assembly in Victoria Falls, Zimbabwe in October of 2003. Iscarsah continues to work on the Guidelines, which are to be used in tandem with the Principles for those involved with technical aspects of preservation.
PDF formats of the Iscarsah Principles can be found in the section of this website, in English, French, Spanish, Italian, Turkish, Bosnian, Arabic, Farsi, Georgian, Slovenian and Romanian.

ISCARSAH at International Conferences
Sep 24, 2026
International conferences are always a valuable opportunity to exchange ideas, learn about the latest developments in the field, and reconnect with colleagues and friends.
A group of ISCARSAH members met in Athens, Greece, at the 4th International Symposium on Geotechnical Engineering for the Preservation of Monuments and Historic Sites (TC301 – Athens 2026).
The programme included two keynote lectures delivered by ISCARSAH members: Prof. Gorun Arun on substructure design of ancient master builders, and Prof. Koenraad Van Balen on evolving conservation principles and interdisciplinary collaboration for cultural heritage preservation.
Participants also had a unique technical visit to the Acropolis of Athens, including access to the Parthenon and the opportunity to observe the ongoing restoration works.
Over the same days, ISCARSAH members were also present in Berlin, Germany, at the European Conference on Earthquake Engineering (ECEE2026), contributing to discussions on the seismic assessment and protection of existing and heritage structures.
From geotechnical challenges to earthquake engineering, ISCARSAH was represented across different international events, with its members contributing to discussions on the protection of built heritage.
Meet the ISCARSAH Working Groups: Climate Change Adaptation
Sep 4, 2026
How can we protect heritage structures from climate hazards while respecting conservation principles? This was the challenge addressed by the ISCARSAH Climate Change Adaptation Working Group.
The Working Group brought together 11 members from 10 countries, combining expertise from different disciplines and professional backgrounds. Together, they investigated the threats that climate-related hazards — including floods, fires, storms, and landslides — pose to cultural heritage, and explored how heritage structures can be protected while respecting conservation principles.
The group's main output was the peer-reviewed paper "Preserving the Past, Protecting the Future: A Framework for Sustainable Climate Adaptation of Heritage Structures", published in the International Journal of Architectural Heritage and available in our Documents section.
The paper proposed a structured, multi-criteria decision-making tool for evaluating climate adaptation interventions, weighing five key dimensions — conservation, resilience, sustainability, feasibility, and socio-cultural impact — and a typology of intervention types: Abstention, Relocation, Circumvention, and Direct Interventions (Mitigation, Reconstitution, Substitution).
The broader goal of the Working Group was to bridge the gap between high-level climate policy and on-the-ground heritage conservation practice, fostering more transparent, interdisciplinary dialogue among conservators, engineers, climate scientists, and local communities.
