Boyuk Zira (Nargin Island)

Boyuk Zira, historically referred to in some sources as Nargin Island, is one of the islands of the Baku Archipelago in Baku Bay on the Caspian Sea. Contemporary encyclopedic sources identify the island by its Azerbaijani name and place it in the maritime approaches to Baku. Declassified U.S. intelligence imagery and analysis from the 1960s document the presence of a microwave communications facility on Nargin Island, including at least one mast-mounted microwave dish antenna, a probable 150-foot guyed mast, and an associated control building; a March 1968 CIA photographic interpretation report also notes a possible SA-2 SAM site located nearby. These archival documents place the island in the Cold War-era intelligence and technical mapping context. The supplied research notes and archival documents do not contain eyewitness accounts, folkloric narratives, or primary-source descriptions of hauntings, apparitions, lighthouse ghosts, or wartime-related paranormal phenomena on Boyuk Zira/Nargin. While the research brief that motivated this entry referenced alleged "wartime and lighthouse hauntings," the provided sources do not corroborate any such claims; no named entities, reported supernatural events, or folkloric interpretations appear in the supplied material. Further research recommended by the investigator includes consulting Azerbaijani-language local histories, maritime and lighthouse records, Soviet-era archives, and oral-history collections to establish whether a folkloric or paranormal tradition exists for the island.
