Structural health monitoring of the Athenian Acropolis' Walls via optical fibre sensors, accelerographs and numerical simulations

A novel structural health monitoring approach using optical fibre sensors and accelerographs on the Athenian Acropolis' South Wall has revealed critical insights into the stability of this ancient gravity wall. The study, conducted over several years, identified characteristic strain and acceleration patterns that provide a deeper understanding of the wall's response to environmental factors. This methodology, developed in collaboration with the Acropolis Restoration Service, offers a non-invasive way to assess the structural integrity of historical monuments, contributing valuable data for their preservation. The findings highlight the potential of optical fibre sensors in long-term monitoring of heritage sites.
