Medieval Archaeology of the South Caucasus (MASC) is a collaborative research project based at the Oriental Institute of the University of Chicago, and run in close collaboration with archaeologists at the Republic of Armenia National Academy of Sciences Institute of Archaeology and Ethnography. We research the archaeology and history of medieval Armenia and its neighbors, thinking about how the South Caucasus in the medieval period (AD 500-1500) was a dynamic region criscrossed by travelers of different kinds: merchants, pilgrims, explorers, and holy warriors of different faiths.
