The video above explains the Sphinx Project’s origins and how Mark Lehner’s work at the Sphinx led to the creation of AERA.

ARCE Sphinx Project 1979-1983
Before the launch of the American Research Center in Egypt (ARCE) Sphinx Project in 1979, no scale drawings of the Sphinx had ever been made.

Directed by Dr. James Allen with Dr. Mark Lehner as field director, this project produced the first detailed scale plans of the Sphinx—a master plan, top plans, elevations, sections, and profiles. It also mapped masonry repairs, the adjacent temples, the Sphinx amphitheater, and the structural geology of the site.

The ARCE Sphinx Project (1979-1983) Online Data Archive

Collecting data at the Great Sphinx of GizaWhile the original ARCE Sphinx project produced a vast trove of material—364 maps and drawings, 3,857 35mm slides, 1,740 black and white photographs, numerous reports, journals, and survey data—this data remained mostly inaccessible to other researchers. Preserving this data was especially crucial as subsequent conservation work at the Sphinx has left some of the areas that were documented no longer visible, leaving the Sphinx Project archive their only record.

Thanks to a grant from ARCE, in 2016 we began a new project to digitize the entire original Sphinx archive, both to preserve the data and to make it freely available to other researchers worldwide. The Sphinx Project data archive is now available online at Open Context. Learn more about the online data, browse selected photos, and learn how to access the full data set.

A brief overview and an in-depth report on both ARCE Sphinx projects are available on the ARCE website.

Return to the Sphinx Viewing Project (RSVP)

Directed by Zahi Hawass and Mark Lehner, the goal of the RSVP was to collect information from the 30 years of work that has been carried out at the Sphinx since the original 1979 Sphinx Project, as well as to use new technologies not available at the time of the original project to better examine and document the area.

Beginning in 2018, we used both traditional mapping, topographic survey, and ground penetrating radar to first document the base of the Sphinx and its surrounding area. We then returned in 2019 to focus on the Sphinx Temple and the area to its east. In addition, a Japanese team directed by AERA team member Yukinori Kawae carried out 3D recordings by drone, photogrammetry, and laser scanning to create a complete 3D image of the Sphinx.
