The TRIQUETRA project aims at creating an evidence-based assessment platform 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.

The overall approach of Triquetra is based on three distinct steps:
1. Risk Identification
2. Risk Quantification
3. Risk Mitigation

This “trifecta” approach (hence the name Triquetra) creates a framework of risk assessment and risk mitigation so as to tackle as many of these risks as possible, in the most efficient way available.

A total of 21 organizations from 7 countries participate in the project, including 8 Universities and Research Organizations and 6 Cultural Heritage Authorities. The project started on 01/01/2023 and will last for 3 years. TRIQUETRA project is funded from the EU HE research and innovation programme under GA No. 101094818.

Addresed Cultural Heritage Typologies

Mainland – rural areas are less likely to be shielded in remote areas with scarce population and lack of surrounding infrastructure.

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.

Novel Tools for In-situ Sensing & Monitoring

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.

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.
