Pejman Akbarzadeh is making a new documentary about the Sassanian fortress Darband in Daghestan, which is the largest known (pre-Islamic) Iranian defensive structure in Caucasus. Despite being registered as a UNESCO World Heritage Site, the latter remains (excepting among specialized scholars) remarkably unknown internationally, even among contemporary Iranians.

The Persian Heritage Foundation, founded in the 1980s by the late Ehsan Yarshater (1920-2018; one of the primary editors of the Encyclopedia Iranica) has agreed to cover 50% of the production costs. Pejman will be traveling to Daghestan in October 2019 in order to film the fortress and to interview Murtazali Gadjiev (The Institute of History, Archeology and Ethnography of the Daghestan Scientific Centre of Russian Academy of Sciences).
