Dig-for-a-Day is based in the Tel Maresha area of Israel's Beit Guvrin National Park. The excavation site is licensed by the Israel Antiquities Authority and operates as a full-fledged research project, supervised by Dr. Ian Stern and under the academic umbrella of the Nelson Glueck School of Biblical Archaeology of the University of Haifa. All discoveries made on a Dig are analyzed and cataloged – some of which are now displayed in the Israel Museum in Jerusalem and are featured in academic publications.

The archaeological site contains some 3,500 underground chambers distributed among distinct complexes carved in the thick and homogenous soft chalk of Lower Judea under the former towns of Maresha and Bet Guvrin. Situated on the crossroads of trade routes to Mesopotamia and Egypt, the site bears witness to the region’s tapestry of cultures and their evolution over more than 2,000 years from the 8^th century BCE—when Maresha, the older of the two towns was built—to the time of the Crusaders. These quarried caves served as cisterns, oil presses, baths, columbaria (dovecotes), stables, places of religious worship, hideaways and, on the outskirts of the towns, burial areas. Some of the larger chambers feature vaulted arches and supporting pillars (CC-BY-SA IGO 3.0).

Tel Maresha is part of the Bet Guvrin-Maresha National Park, under the Israel Nature and Parks Authority.
