The Sinai Digital Archive is a collaborative digital project that supports inter-institutional sharing of archives into a single, public, and scholarly resource. The project makes available for study, teaching, and research the vast collections of icons, manuscripts, liturgical objects, and archival material from the Monastery of Saint Catherine at Mount Sinai. This website brings together for the first time the photographic archives from the Michigan-Princeton-Alexandria Expeditions to Sinai in 1956, 1958, 1960, 1963, and 1965, now held in the Visual Resources Collections at Princeton University and the University of Michigan. The images display the scans of the 5 x 7 inch Ektachrome transparencies and the 35mm slides in color and black & white from the "Sinai Archives" at both institutions.

The Sinai Digital Archive was awarded the 2023 Digital Humanities and Multimedia Studies Prize from The Medieval Academy of America. 

The project has received support from Princeton University, the University of Michigan, and Tufts University, in collaboration with Saint Catherine Monastery at Mount Sinai.
