The surface survey at Mount Oxa started in 2017 under the auspices of the Byzantine and post-Byzantine Department of the Ministry of Culture and Sport (protocol number: ΥΠΠΟΑ/ΓΔΑΠΚ/ΔΒΜΑ/ΤΕΕΑΕΙ/ 357358/233390/6024/541). This deliberation granted the permission to the Ephorate of Antiquities of Lassithi to begin a new surface survey on Mount Oxa in collaboration with the Laboratory of Geophysical Satellite Remote Sensing and ArchaeoEnvironment at the Institute for Mediterranean Studies (FORTH), in a program articulated in three years (2017-2019).
