[2018] Assessment on how to collect external data (weather, seismic activity) and internal data (geometry, dimensions, constituent materials, cracks) to determine the state of conservation of a Roman temple in Egypt. Aim: to help a team of conservator-restorers to establish a plan of preliminary tests and data collection that would make it possible to determine the risk of collapse of the temple and thus be able to work safely during the conservation intervention campaigns of the temple.
