The International Congress of Speleology in Artificial Cavities; Hypogea 2015 took place in Rome during March 11-17th, 2015. The event was organized by Hypogea. Union of Speleology and SSI (Società Speleologica Italiana) gave their patronage, together with CNR (Consiglio Nazionale delle Ricerche – Dipartimento Scienze del Sistema Terra e Tecnologie per l’Ambiente), Istituto di Ricerca per la Protezione Idrogeologica, Parco Regionale dei Castelli Romani and SIGEA (Società Italiana di Geologia Ambientale).
150 scholars took part in the event, from Austria, Armenia, Bulgaria, Czech Republic, Croatia, France, Georgia, Germany, Israel, Italy, Russia, Switzerland, Turkey, UK and USA. It was the ideal context to share important multidisciplinary researches and to speak and to compare on different topics. Over and above lectures on specific underground sites, other topics have been discussed, such as the study and the census of ancient hydraulic and religious works, new technologies used during explorations and topographical survey of artificial cavities, analysis of specific speleothems, mines with the related risks during their explorations, underwater speleological explorations and comparisons between different typologies of artificial cavities in different countries, their filing and codification.
During the HYPOGEA 2015 Congress several underground visits took place in and outside Rome. Those tours gave the opportunity to “travel” during 23 centuries (from 6th century BC to 17th century AD), exploring archaic water drains, mithraeums, ancient aquaeducts, tuff mines and ancient roman houses, nimphaeus and inquisition cells.
