Toolbox for assessing and mitigating Climate Change risks
and natural hazards threatening cultural heritage

EXPLORE
TRIQUETRA (/traɪˈkwɛtrə/) from the Latin triquetrus “three-cornered”:
An ancient symbol (triangular figure composed of three interlaced arcs),
often used to represent the 3 fundamental elements – air, water, and
earth or the infinite cycle of life. Also known as a rune of protection.

THE PROJECT

Cultural Heritage (CH) monuments are often exposed to extremely unfavourable conditions (such as water-related hazards). The TRIQUETRA project aims at creating an evidence-based assessment platform for tackling CC risks and natural hazards threatening CH, that allows precise risk stratification and also creates a database of available mitigation measures and strategies, acting as a Decision Support Tool towards efficient risk mitigation and site remediation.

Remote & In-Situ Sensing

TRIQUETRA’s data collection will provide an insight to all the variables directly or indirectly connected to CC, comparing them with historical data. New innovative surveying techniques are utilized: Hydrographic surveys, multi-beam sonars, UAVs with optical, multispectral & LiDAR sensors, underwater photogrammetry, laser spectroscopy, novel simulation models and more.

Addressed CH Typologies

Underwater sites are increasingly affected by climate change (e.g. changes in the chemical composition of oceans).
Coastal areas shall be a focus for the approach to validate its various water-protection and water-related damage detecting techniques.
Mainland – rural areas are less likely to be shielded in remote areas with scarce population and lack of surrounding infrastructure.

Decision Support Platform

By integrating all the modules and technologies in TRIQUETRA, a DSS will be developed and validated in actual working conditions in 8 different pilot sites across Europe, spanning a wide range of archaeological periods, CH typology, structures and materials.



PILOT SITES

TRIQUETRA will be validated in 8 different CH sites across Europe (1 in Italy, 3 in Greece, 1 in Germany, 1 in Switzerland, 1 in Cyprus and 1 in Poland), spanning a wide range of archaeological periods, Cultural Heritage typologies, structures and materials.
