The paper presents the report about the excavation campaign at Qumran cave 11Q, carried out from 9th to 19th March 2017 by the Istituto di cultura e archeologia delle terre bibliche of the Facoltà di Teologia di Lugano (ISCAB-FTL) and by the Università della Svizzera Italiana (USI). Previous archaeological excavations, undertaken by Roland de Vaux (1956) and Joseph Patrick (1988 and 1991), were published in brief preliminary reports only. The 2017 archaeological campaign, complemented by speleological and geological investigation, enriched the dossier for the forthcoming final report. Among the main results are: the discovery of an upper chamber; the opening of a sounding in an area barely interested by previous excavations; the analysis of the entrance area and the natural factors which may concur to the closure of the cave; the documentation of 11Q morphology employing modern technology (3D scan)
