Casa Blanca — Antiguo Cuscatlán

Research into the name "Casa Blanca" as a haunted or notable site in Antiguo Cuscatlán yields no direct matches in the provided source corpus. The sources supplied reference multiple distinct uses of the phrase "Casa Blanca" or "Casablanca" (including the city Casablanca in Morocco, a Mexican town named Casa Blanca, a U.S. library branch, and an image caption describing a modernist white house) but none explicitly identify a building or location called Casa Blanca located in Antiguo Cuscatlán, El Salvador. There is no construction, ownership, or event history for a Casa Blanca in Antiguo Cuscatlán in the materials provided. Because the supplied sources do not contain eyewitness accounts, folkloric narratives, or documented phenomena tied to a Casa Blanca in Antiguo Cuscatlán, no paranormal claims can be substantiated from this corpus. The only regional context in the materials is a general note that Antiguo Cuscatlán is part of the San Salvador metropolitan/economic area; this contextual reference does not link to any Casa Blanca site or tradition. Further, location-specific research (local histories, newspapers, municipal records, or oral folklore collections) would be necessary to establish the identity, history, or any alleged phenomena for a Casa Blanca in Antiguo Cuscatlán.
