Emprises bâties supposées des ouvrages souterrains (anciennes fortifications)Presumed built footprints of underground structures (former fortifications)
This dataset provides a digitized map of underground passages belonging to the former fortifications of Geneva (16th–18th century). The footprints were reconstructed from original plans and historical surveys dating from the 18th to 20th centuries, including field surveys carried out in the 1970s by the cantonal geology service, as well as hypothetical reconstructions attributed to researchers such as Louis Blondel. The dataset is published by the Système d'information du territoire genevois (SITG), the geographic information system of the Canton of Geneva, and is useful for heritage studies, urban planning, and risk assessment related to underground voids.Les souterrains des anciennes fortifications (XVIe-XVIIIe siècle) ont été digitalisés sur la base de plans d'origine et de relevés anciens (XVIIIe-XXe siècle), de relevés effectués dans les années 1970 par le Service cantonal de géologie, de reconstitutions hypothétiques (Louis Blondel et Anastazja…
