Since 2018, the Hellenic Survey of Geology and Mineral Exploration (EAGME) has been implementing a research project titled “Recording of Stone Bridges in the Region of Epirus Affected by Natural Disasters,” under the scientific supervision of Dr. Panagiotis Paschos, Geologist of EAGME’s Regional Unit of Epirus.
The Region of Epirus hosts numerous stone bridges, a result of its rugged terrain and the intricate division of its hydrographic network. These bridges are architectural monuments of remarkable aesthetic value and form an integral part of the region’s cultural identity. However, the impact of destructive natural processes (earthquakes, floods, landslides, etc.), as well as human interventions in some cases, has led to the gradual deterioration of these monuments.
The main goal of this research project is to identify and describe stone bridges whose foundations have been affected by ongoing erosion processes, particularly under flood conditions, where the cumulative effects could potentially be catastrophic for certain structures.
The aim is to establish a geological risk classification system, enabling early diagnosis and forecasting, as well as timely intervention measures by state authorities (Municipalities, Regional Government, etc.).
The data collection and evaluation are being carried out in collaboration with the municipalities of the Region of Epirus and the Service of Modern Monuments and Technical Works of Epirus, the Ionian Islands, and Western Macedonia, which as competent authorities, possess a comprehensive understanding of the priorities and existing conditions.
To date, on-site inspections have been completed for 27 stone bridges, and relevant reports have been sent to the municipalities of Metsovo, Zagori, Konitsa, Dodoni, and Georgios Karaiskakis, while similar reports for the municipalities of Northern Tzoumerka, Central Tzoumerka, and Pogoni are being finalized and will be delivered soon.
Finally, it is worth noting that following the submission of EAGME’s recommendations, several municipalities have already implemented simple yet crucial protective measures for the bridges—such as flow management, vegetation clearance, and the construction of embankments at the piers—ensuring the preservation of these intricate stone structures. Built to overcome natural obstacles, these bridges have maintained human connectivity for decades and remain an admirable legacy, a defining hallmark of the master builders of Epirus.
