Sinkholes are a well-known geologic hazard but their past occurrence, useful for
subsidence risk prediction, is difficult to define, especially for ancient
historic times. Consequently, our knowledge about Holocene carbonate landscapes
is often limited. A multidisciplinary study of Trieste Karst (Italy), close to
early Roman military fortifications, led to the identification of possible
ancient road tracks, cut by at least one sinkhole. Electrical Resistivity
Tomography through the sinkhole has suggested the presence of a cave below its
bottom, possibly responsible of the sinkhole formation, while Ground Penetrating
Radar has detected no tectonic disturbances underneath the tracks. Additionally,
archaeological surveys led to the discovery of over 200 Roman shoe hobnails
within or close to the investigated route. According to these data, the tracks
are interpreted as the remains of a main Roman road, whose itinerary has been
reconstructed for more than 4 km together with other elements of ancient
landscape. Our results provide the first known evidence of a Roman main road
swallowed by sinkholes and suggest that Holocene karst landscapes could be much
different from what previously believed. In fact, sinkholes visible nowadays in
the investigated region could have been flat areas filled by sediments up to the
Roman time.
